Step by Step<br />

AAt the moment you get the impression that light aviation,<br />

even aviation in general, is in the fast lane and is on the way<br />

with Seven-league boots.<br />

This year opened with the Elevate announcement from Uber,<br />

the taxi service, and in autumn two air taxis were seen at the<br />

International Motor Show (IAA) in Frankfurt.<br />

The financial markets as well are investing: Mercedes has<br />

a 10 per cent stake in Volocopter; Lilium has just collected<br />

90 million euros with their vertical-launch project Lilium-Jet.<br />

At the largest car show in the world, the Slovakian Aeromobil-<br />

Flugauto (flight Car) could be seen alongside the Volocopter.<br />

This is quite an interesting approach, but by many, usually<br />

self-proclaimed “experts” tell everyone without being asked<br />

that these devices are completely out when the VTOL aircraft<br />

will comes there.<br />

We, Flying Pages, have been supporting the electrification of<br />

light aviation for years; we have launched the e-flight Expo<br />

and the e-flight show at the AERO and will now be hosting<br />

the e-flight Forum in Beijing this November.<br />

But these rose-colored future-predictions, you may have<br />

heard last month, seems to be a little bit muted. “Our VTOL<br />

vehicle is to be approved as General Aviation / LSA and approval<br />

will be completed in the next two years so that sales<br />

can begin.” If a journalist asks one of the CEO’s this is one of<br />

the stereotypical timetables they like to offer and like to have<br />

quoted by the journalist. Very seldom will a journalist ask further<br />

questions or dig deeper.<br />

However the fact is, although technical problems, which are<br />

undoubtedly still there, can be solved faster with the flood of<br />

money which is now engaging into aviation and even if the<br />

super batteries will come in the following years, one thing,<br />

which nearly all forecasts absolutely underestimate is the<br />

certification.<br />

Remember how long it took to change to the new radios,<br />

how elaborate and laborious it is to get a certification for a<br />

new glass cockpit and how expensive this process is? If you<br />

think of this, then at least a decade - if not even more - will<br />

pass by before autonomous flying, vertical-flight flight-taxis<br />

will be allowed for passenger transport. Admittedly the regulatory<br />

authorities have moved and set a new milestone with<br />

the new Part 23.<br />

However, before a VTOL not only can fly as a prototype but<br />

with certification a lot of water will flow down the Rhine river.<br />

After all, the failure-proof and redundancy systems of this<br />

totally new technology have to be proved and extensively<br />

tested (alone and in combinations). At the moment most e-<br />

planes have a very short time in the air because the required<br />

flight time reserve limits the actual available real flight time to<br />

a few minutes.<br />

Remember how long it took to get the certification for the<br />

first ballistic recovery system, to save a plane in whole for a<br />

GA plane as well as it being very expensive. This was still the<br />

fact although this system was already used in ultralight aircraft<br />

and had already saved dozens of lives.<br />

Bridging Technology<br />

Against this background, it seems to be a good idea to look<br />

first at old-fashioned fixed wing planes equipped with electric<br />

motors and hybrid devices. Then test these planes and<br />

develop the necessary safety standards, approvals and operating<br />

criteria together with the authorities.<br />

So when the VTOL devices really will come, EASA and Co.<br />

already know how to deal with larger battery packs in the air<br />

and which (approval) requirements are to be placed on the<br />

control software.<br />

The next step will then be airplanes with many electric motors,<br />

which may also start vertically in the future. Of course,<br />

where they can take off and land, that is a completely different<br />

question.<br />

If you accept these “normal” e-planes as bridging technology,<br />

then the flight cars with wings, like the aforementioned<br />

Aeromobile or the Carplane, are a step on the way to certificate<br />

an approve of novel electric planes.<br />

But one thing is clear: even if Air taxis are certified and massproduced<br />

in future, most of the novel airplanes (and their<br />

technology) have been developed in the microlight sector.<br />

Only in a deregulated environment a rapid advancing technology<br />

will unfold. In order to make this happen for the electric<br />

flight in the near future, the MTOW for double-seated ultralights<br />

must be clearly raised, best to 600 Kg.<br />

The only alternative is that the EASA will significantly deeggle/deregulate<br />

its classes, starting with the LSA, and adapting<br />

it to the UL world, but this will probably remain forever<br />

only a beautiful dream.<br />

Kitty Hawk<br />

Larry r Page’s<br />

Sky Motorcycle<br />

A seat and handlebars like a motorcycle, a control unit,<br />

four struts and eight propellers – is this the ultralight of the<br />

future? Not likely! But the machine from Kitty Hawk, the<br />

second aviation company from Google founder Larry Page,<br />

is certainly an interesting approach. It’s a single-seat,<br />

manned drone, which is designed to fly under the American<br />

Part 103 regulations (without a pilot license, registration<br />

or airworthiness certificates), but only over water.<br />

TThe Kitty Hawk company has been working quietly for more<br />

than two years: People only knew that the money came from<br />

Google founder and Alphabet chief Larry Page and that Page<br />

with Zee Aero (and their work on vertical takeoff airplanes) was<br />

yet another iron in the fire.<br />

Then this past April came the bombshell: shortly after the first<br />

flight of the unmanned Lilium in Germany, Kitty Hawk showed<br />

their project - and the world was amazed! One day before the<br />

big Uber Elevate Summit in Dallas, they showed not an airtaxi<br />

nor autonomous aircraft but instead - in the truest sense a ‘Just<br />

for Fun’ aircraft - an air motorcycle, a jet ski for the sky.<br />

The air moped made its first public appearance at Oshkosh.<br />

The spectacle was scheduled to take place at 9:00 am, and at<br />

8:30am the beach at the Seaplane Base at Lake Winnebago<br />

was slowly filling up - quite unusual, because normally there<br />

in the shade of the old trees, the few people there find it rather<br />

relaxed. First up, Communications Manager Ellen Cohen explained<br />

how the flights would proceed: A flight of three minutes,<br />

landing on the pontoon, battery change, and then a second<br />

flight. Technical questions would only be answered in a limited<br />

way. The flyer could be seen on a floating platform at a footbridge.<br />

The plane was connected via a Datalink to a computer<br />

station, which records, stores and evaluates all data.<br />

Then it’s time. Todd climbs onto the flyer. Assistants take the<br />

propeller guards from the eight twin-blade propellers. There<br />

are a few, small remaining checks and then the propellers howl<br />

to life. The Flyer, with Todd aboard, slowly climbs into the sky,<br />

then he pulls past us and performs some pirouettes and some<br />

fly-bys at different speeds. Sometimes Todd lowers the device<br />

slowly to nearly the water surface, then rises again to its limited<br />

maximum height of about 15 feet. The flyer is equipped with a<br />

laser altimeter that ensures that it does not climb more than 15<br />

feet above the water. “Of course the machine could technically<br />

fly higher,” explained Reichert later in the interview, “but in the<br />

current test phase we have limited the height.” “Why is the pilot<br />

sitting relatively stiffly on the machine?” was another question.<br />

“The machine is piloted by the control units on the ‘handlebars,’<br />

it is not about weight shifting - even though it would react<br />

to it,” says Todd, “but we have found that this is the most precise<br />

method of steering.” There are various buttons on the handlebars<br />

to control the vehicle. The throttle is a small knob on the<br />

left-hand tip of the handlebars. The throttle is used to regulate<br />

the height. On the right handlebar is the ‘pitch’ lever, which allows<br />

you to move the machine back and forth. Using the index<br />

finger on the left hand, another lever, the ‘yaw’ control, rotates<br />

the device around its own axis.<br />

Actually, the machine is not balanced by the pilot’s controls, because<br />

it is - like any other unmanned multicopter - controlled by<br />

several gyros that in turn drive the multiple propellers through<br />

redundant computers.<br />

Aerodynamics<br />

and Configuration<br />

at Kitty<br />

Hawk.<br />

Then it’s over. After the first landing, there is a<br />

second short flight which goes much like the<br />

first.<br />

After the final landing, the questions are dominated by price, but<br />

Kitty Hawk won’t give away anything, even a price frame they<br />

would announce or confirm. But what is certain: in the fall, the<br />

flyer is to be offered for sale, when the maximum flight time is to<br />

be significantly increased. And if you want, for $100 you can already<br />

become a member of the Kitty Hawk Club, which among<br />

other things will provide a discount of $2000 off the retail price<br />

of the Flyer.<br />

Light weight engines and propellers are designed in-house at Kitty<br />

Hawk for their own production.<br />

While Robertson is still being interviewed, his team stashes the<br />

Flyer on a red pickup truck, ties it down, and then it’s gone<br />

again. In the photos we caught, it becomes clear that it’s still<br />

a prototype: complete with cable ties, loose cables and tape.<br />

But when machines look like that, then you can still try out a lot<br />

of things. The first impression is that the flyer is stable in the air<br />

and reacts quickly and precisely to the control input, like many<br />

other multicopters, but of course it is slightly larger.<br />

How does one learn to fly the Flyer? Todd and his crew are<br />

convinced that mastery of the machine can be gained in a few<br />

hours. Whether or not this will actually be the case, the future<br />

will show. After all, the machine is quick (up to 24 mph) - and<br />

the aspiring pilot will probably have to learn some emergency<br />

maneuvers.<br />

The Flyer is a Part 103 Ultralight<br />

Just as at the beginning of the eighties of the last century, when<br />

inventors and backyard mechanics for the then-new deregulated<br />

class invented brand new aircraft for production and sales,<br />

the high-tech nerds from the Silicon Valley also want to build<br />

flying machines under the ultralight category carved out by the<br />

American aviation authority, the Federal Aviation Administration.<br />

Part 103 of the FAA regulations state that airplanes with an empty<br />

weight of less than 254 pounds (115 Kg) are permitted to<br />

be built to fly without airworthiness certificates. And even better:<br />

for ultralights, those flying them do not need pilot licenses<br />

or airports.<br />

Part 103 also limits ultralights to a fuel capacity maximum of<br />

five gallons (approximately 19 liters), a minimum speed of 24<br />

knots (44 km/h) and a maximum speed of 55 knots (1<strong>02</strong> km/h)<br />

observed.<br />

These hurdles are also likely to be overcome. Part 103 states<br />

that the empty weight of 254 pounds does not include a weight<br />

allowance for aircraft floats. This means that the Kitty Hawkers<br />

can pull the weight of their floats from the empty weight. This<br />

is necessary because, as Rodd Reichert admitted in Oshkosh,<br />

currently the machine is still clearly above the weight limit; but<br />

that could be overcome.<br />

Why Kitty Hawk<br />

The reason why Larry Page’s air motorcycle is called the Kitty<br />

Hawk Flyer is simple: on the dunes of Kitty Hawk in North<br />

Carolina, the Wright brothers and their Wright Flyers first took<br />

off; the Wright brothers themselves called their plane “The<br />

Whopper Flying Machine.” The Kitty Hawk wants to lean on this<br />

historic vehicle, and hopes that they can revolutionize transport<br />

as well as did the Brothers Wright. An interesting further parallel<br />

between the design teams: the Wright Brothers produced and<br />

repaired bicycles, Cameron Robertson and Todd Reichert, the<br />

technical directors of Kitty Hawk, earned their first spurs in aviation<br />

with the Canadian company Aerovelo. The spin-off of the<br />

University of Toronto built the bike-helicopter Atlas a few years<br />

ago, a helicopter operated by muscular force which won the<br />

Sikorsky Prize. The helicopter flew - driven only by the muscle<br />

power of the pilot - 3.30 meters high and remained in the air for<br />

64 seconds. They also won a prize for the fastest bike.<br />

Conclusion<br />

Did I see the future of ultralight flying or even general aviation<br />

at the Seaplane Base in Oshkosh? Yes and no. Yes, because I<br />

believe that the future of drive technology will soon be mainly<br />

electric in aviation, and yes, many of the test vehicles will also<br />

be flying as ultralights in the next few years. That is because it<br />

is simply the least regulated class of aircraft and it allows designs<br />

to be tested the fastest and with the fewest bureaucratic<br />

barriers.<br />

No, because people want to fly higher than five meters and not<br />

just over water. Although the machine can technically fly over<br />

land, it lacks the redundancy needed to make overland flight<br />

safe.<br />

No, because if you want to fly to get somewhere, the lift is simply<br />

too ineffective. We will still need wings for a long time. This<br />

is especially the case while we wait for advances in the low energy<br />

density of the batteries used to power aircraft.<br />

The Kitty Hawk Flyer is as much the future of air transport as<br />

the jet ski was the future of boating. But like jet skis, it is certainly<br />

going to be a lot of fun and will find its place in the market.<br />

Two men could load the ultralight aircraft, which has a target<br />

empty weight of 254 pounds.<br />

The long way to the electrical future<br />

English Channel crossing<br />

and MGM COMPRO<br />

Every aviation enthusiast knows the Airbus E-Fan, which took off at<br />

Lydd (UK) on July 10th 2015, and landed 37 minutes later at Calais<br />

in France lying 75 miles away. Under great media attention, Airbus<br />

celebrated afterwards the first Channel crossing with a manned allelectric<br />

plane. However, few insiders knew that the heart piece of the<br />

aircraft - namely the electric drive system – had significant contribution<br />

from a small Czech electric drive manufacturer. Who is behind it?<br />

tMGM Compro<br />

The story of the small Czech firm began in 1998, when a frustrated<br />

businessman named Boris Guič returned to his old<br />

passion for the flying of airplane models. Delighted by the<br />

technical progress that has taken place in the meantime, he<br />

began to build his own models with electric drives. E-motors<br />

with up to 7 kW power have been developed, so that model<br />

airplanes with a span of 2.6 m could be propelled. But if you<br />

wanted even higher performance, things got complicated,<br />

because then sophisticated power electronics had to be<br />

implemented. At this time, Mr. Grisa Dvorsky, the owner<br />

of MGM COMPRO, offered him help. The Czech company<br />

MGM COMPRO located in Zlin already had an excellent reputation<br />

in the production of model electronics and industrial<br />

controllers. Mr. Guič was looking for a controller to control<br />

his powerful engine, while Mr. Dvorsky was looking for a<br />

powerful engine to fully load his controller.<br />

Grisa and Martin Dvorsky (photo right) are the main persons from<br />

MGM COMPRO. They offer power electronics not only for models<br />

but also powertrains for larger aircraft.<br />

Ah battery (<strong>36</strong>0<br />

V). The flight<br />

duration is 60<br />

minutes.<br />

In the following years, MGM COMPRO had to overcome numerous<br />

challenges to bring about the success of the complex<br />

electric drive systems. Innumerable problems arose in<br />

the field of sensors, in the monitoring of critical parameters,<br />

in the emergency disconnection system and in the braking<br />

system, just to name a few examples. In the end, the components<br />

developed by MGM COMPRO included the electronic<br />

speed controller, the battery management system (BMS),<br />

the battery packs, the chargers, etc., i.e. the entire electric<br />

drive system except the engine. At the same time, a new<br />

company named RotexElectric was set up to focus on the<br />

production of industrial and aviation engines. Nowadays,<br />

this brand offers air-cooled and water-cooled electric motors<br />

from 10 kW to 100 kW, with a 160 kW engine already in<br />

the development phase.<br />

Once the barrier to higher performance has been surpassed,<br />

the aviation engines are used in manned hang<br />

gliders, motorized paragliders, UL trikes and motorized<br />

sailplanes. A prominent customer is the foot-launched highend<br />

glider Archeopteryx designed by Ruppert Composite<br />

from Switzerland. Elec’teryx’ electrically powered self-starting<br />

version uses the MGM COMPRO RET 30 engine (12 kW<br />

and 4.1 kg). In conjunction with two battery cells with a total<br />

capacity of 40 Ah, the motor glider can climb to 1300 meters<br />

in 11 minutes at full thrust, whereas a flight duration of<br />

60 minutes is possible under normal flight conditions. The<br />

entire electric drive system (including battery) weighs 23 kg<br />

and can be mounted and removed within 5 minutes.<br />

Electric motor<br />

The currently strongest electric motor in the portfolio of<br />

MGM COMPRO is the REB 90 with a maximum output of<br />

80 kW. It is a special development for the project SportStar<br />

EPOS (Electric Powered Small Aircraft) of the Czech aircraft<br />

manufacturer Evektor. The SportStar EPOS, still in development,<br />

is a concept for the sport aircraft of the future, combining<br />

eco-friendly flying with low operating and maintenance<br />

costs. MGM COMPRO also supplies the power electronics<br />

in this case, which enables optimal use of the stored electrical<br />

energy. In addition to the known advantages of electric<br />

flying, such as zero Carbon and low noise emissions,<br />

the net energy cost of the flight is about 75% lower than<br />

in aircraft with internal combustion engines. Furthermore,<br />

the number of components in an electric drive train is almost<br />

90% less than is the case with conventional combustion<br />

engines, which clearly shows lower maintenance costs<br />

The Airbus E-Fan mentioned earlier used four RET 60 (25<br />

kW) motors for driving the two ducted propellers. An interesting<br />

detail is that Airbus engineers also installed a 7 kW<br />

REG 30 engine to drive the main gear to minimize the inefficient<br />

thrust generation through propeller at low ground<br />

speeds. Thus, the company MGM COMPRO contributed<br />

decisively to the Airbus success in the Channel crossing.<br />

It needs to be mentioned that Airbus officially ended the<br />

E-Fan project in the spring of 2017 to focus on other electric<br />

flight demonstrators.<br />

Other Projects<br />

Another interesting project involving MGM COMPRO<br />

was the CriCriElectric. This joint development of EADS<br />

Innovation Works, Aero Composites Saintonge and Green<br />

CriCri Association is based on the kit CriCri, a mini twin<br />

whose design dates back to the 1960s and had its maiden<br />

flight on July 19, 1973. The first all-electric version of the<br />

CriCri started on September 2, 2010 in Le Bourget for their<br />

first flight. It was equipped with four REG 30 (10 kW) engines<br />

that powered two traction and two pressure propellers. The<br />

electric drive system allows 15 minutes aerobatics, making<br />

the CriCriElectric the only four-engine electric aerobatic aircraft<br />

in the world. In a converted MC15E CriCri equipped<br />

with two Electravia GMPE 104 E engines, each producing<br />

25 kW of maximum power, French stunt pilot Hugues Duval<br />

flew from Calais to Dover and back on the eve of July 10,<br />

2015, the day of the E-Fan channel crossing back. The Aero<br />

Club France then congratulated him on the first all-electric<br />

world record over the English Channel. Another field of application<br />

for the lower power drive trains is the EGO suspension<br />

glide trikes from Ultralight Design. The lightweight single-seater<br />

carbon fiber trikes, together with the AIR surface,<br />

achieve very good flight performance. In addition, the MGM<br />

propulsion systems are also used in the electric SONG UL<br />

aircraft and in various electric motor screen drives.<br />

CriCriElectric with four REG 30 (10 kW) motors, MGM COMPRO<br />

HBC 120120 controller and LiPo 40 Ah battery (120 V). The flight<br />

duration is 45 minutes.<br />

Hybrid-Electric Aircraft<br />

Electric Propulsion & Innovation<br />

Committee<br />

tThe General Aviation<br />

Manufacturers Association<br />

(GAMA) has be at the centre of<br />

the world’s most exciting<br />

aerospace opportunities:<br />

Hybrid-Electric Aircraft.<br />

Through the GAMA Electric<br />

Propulsion & Innovation<br />

Committee (EPIC) GAMA has been<br />

working with the world’s leading space manufactures to address dress challenges<br />

and opportunities which will allow<br />

for incredible new developments<br />

in<br />

aero-<br />

aerospace.<br />

There is no question that one of the most exciting potentials<br />

exists in electric vertical take-off and landing (eVTOL)<br />

aircraft. There isn’t simply one factor alone that is enabling<br />

this new industry but rather the combined availability of technology,<br />

public perception, regulatory policy and a recognition<br />

by capital markets of the tremendous opportunities.<br />

The work of the GAMA EPIC<br />

includes addressing the requirements for the proper design<br />

of electric aircraft, including eVTOL, working with regulators<br />

to bring about new levels of simplified operation<br />

and dealing with infrastructure issues. Currently the GAMA<br />

EPIC is working in great detail with the U.S. Federal Aviation<br />

Administration (FAA) and the European Aviation Safety<br />

Agency (EASA) to assure the design requirements are appropriate<br />

for these vehicles but do not add unnecessary burden.<br />

In the last year, the regulatory environment in these areas<br />

has developed to a very mature stage which is allowing<br />

those involved to move forward with much lower risk that the<br />

safety regulators will raise new concerns as designs mature.<br />

The EPIC is very heavily engaged now in defining new levels<br />

of automation for operations within the traditional aviation<br />

airspace. To make profit with eVTOL designs, there is agreement<br />

that these activities will need to occur at a large scale<br />

in high-density airspace. The work of the GAMA EPIC in defining<br />

what these kinds of operations will look like is of critical<br />

importance to the eVTOL community. If you wish to be a<br />

part of the GAMA EPIC, please contact me to discuss your<br />

level of interest.<br />

5 ACTIONS TO MAKE<br />

URBAN AIR MOBILITY<br />

A REALITY<br />

APPROPRIATE DESIGN REGULATIONS<br />

Innovative designs require safety regulations to keep pace with the<br />

market, so as not to hold back new, safer technologies. With the rollout<br />

of electric & hybrid propulsion, alongside increased automation,<br />

our regulators need to update certification rules to specifically<br />

address new technologies, such as electric vertical take-off & landing<br />

(eVTOL) aircraft. A harmonised global approach is essential.<br />

MODERNISE PILOT LICENSING<br />

Graphics & Information<br />

for Public Campaigns<br />

We have some exciting things planned in the coming<br />

months and we are requesting your assistance in gathering<br />

graphics and videos to increase the level of appeal of<br />

electric propulsion and on-demand mobility to the broader<br />

community.<br />

We are creating some draft materials and web pages for<br />

use in future public campaigns with various government<br />

and public entities around the world and we would like to<br />

include a mix of images that represent the EPIC members.<br />

Prior to releasing these materials we will provide an opportunity<br />

to the EPIC to see them in draft form. Please send us<br />

the following images or videos to assure you can be included<br />

in these materials in the future:<br />

Traditional ways of regulating pilot capabilities will no<br />

longer work. Today we associate having two or more<br />

combustion engines with more complex aircraft. However<br />

new electric/hybrid designs can mean up to 10-20 small<br />

engines, controlled in a highly automated way. A pilot of<br />

an eVTOL aircraft would manage a remarkably simplified<br />

cockpit, either on-board or remotely. .<br />

THE RIGHT OPERATING ENVIRONMENT<br />

eVTOL aircraft promise highly efficient, environmentally-friendly<br />

ways to directly move people in urban areas. However they will need<br />

to operate in airspace shared by many other forms of aviation - from<br />

small cargo-carrying drones to helicopters. Careful planning is vital<br />

so no category of aviation is disadvantaged or exposed to<br />

unnecessary risk.<br />

INFRASTRCTURE & URBAN PLANNING<br />

European mobility plans will need to take more account of<br />

aviation for multi-modal transport solutions, as we seek<br />

ways to limit emissions and time lost in traffic. Cities who<br />

plan ahead to incorporate urban air mobility vehicles will<br />

see the benefit in the coming years - from air taxis to<br />

medical emergency capabilities.<br />

FUTURE-PROOF EU DRONE POLICY<br />

As the EU prioritises building a framework for drones, it<br />

cannot overlook the forthcoming overlap of 'manned<br />

aviation' and unmanned drones. The European<br />

Commission's U-Space framework must not hinder the<br />

development of passenger air travel where a pilot may<br />

not need to be on board, or even directly fly the aircraft.<br />
