Market Watch PURE FLIGHT: A New Electric Aviation Ecosystem The Pure Flight electric aviation project from Czech Republic will have its premiere at AERO and e-flight-expo 2018. At the show the project will present an electric aircraft, electronics of electricity management, three variant of chargers up to superfast version, communication module for aircraft electrification and planned infrastructure construction at selected airports. If the project name “Pure Flight” is new to you, the name of the electric airplane around which the project builds should sound familiar. Phoenix motorglider had its electric version debut at AERO and e-flight-expo in 2011. This time Phoenix comes back together with partners MGM COM- PRO, PEG and SPORT PROP which are specialists in their line of work. AN ECOSYSTEM WITH FOUR PARTNERS CONTRIBUTING TO KEY COMPONENTS E Evektor Project Pure Flight Solutions started officially in September 2017 when Phoenix’s Martin Štepánek initiated with the concept. The mission of the project is to offer electro-flight as an affordable and modern alternative. As a solution that includes a long-lasting electric aircraft, a fast-charging management system and communication infrastructure and an airport infrastructure. The goal is to introduce a system that is accessible to everyone, universal and gives space for its own rapid development and collaboration. To achieve the project goal, Pure Flight’s partnership strategy is important to form a viable ecosystem of electric aviation. Phoenix Air specializes in aircraft and manufacturing, MGM COMPRO is the leader in electronic control and regulation, PEG is superior in heavy-current and chargers, SPORT PROP has years of experience in aviation and prototyping. The most difficulty of the project was to convince and find the way to realization in two stages. The first stage is to introduce a pure electric aircraft with a more than 2 hours endurance, superfast charger and a communication module between the aircraft and the charger. The second stage is to prolong the range of the range extender, the current drive control and the recovery, as well as the implementation of infrastructure at airports. THE UPGRADED ELECTRIC PHOENIX MOTORGLIDER The project will use Phoenix electric motorglider. Since the debut in 2011, the electric Phoenix prototype has accumulated over 400 hours in flight time. The upgraded version developed for this project plans to make first flight in summer soon after AERO. The upgraded Phoenix electric versions will have over 2 hours of endurance plus reserve which will make it on a par with other advanced electric light airplanes. All Phoenix versions are under the Czech Republic LAA CR certification in the ELSA category. It is a category that gives room for development and implementation. I would like to thank LAA ČR for this category, for the possibility of The 100 kW Super Charger Pure Flight can fully charge the electric Phoenix in 20 minutes. 34 e Flight Journal

If Phoenix will be certified also in another category in the future? That is still subject depending on interest in our offered system. THE VARIABLE CHARGING SYSTEM FROM BASIC TO SUPER CHARGER Pure Flight plans to use three types of power charger systems to provide a board selection, varying from 2.5KW all the way up to 100kw super charger depending on the local infrastructure and customer need. The power connector to the airplane will use three standards: CHAdeMO, CCS2 for cars and the third standard is a specially developed connector using the Phoenix Pure Charger module for aircraft for optimized charging. With the 100KW super charging system the theoretic charging time will be about 20 minutes. At the power input, the charger can be powered from any source with 3 x 400/230V power from traction lines up to 1000 V. It may also obtain power from weak power supplies such as solar panels with battery storage. The chargers will be fully compatible for automotive directly, for aircraft using the Phoenix Pure Charger module. This means that a superfast charger can recharge cars and aircraft. One charger may have multiple dispensers. One for cars and the other for airplanes. There are many power options, charging up to 2 x 500 V and 120 A at the moment. This is to say that higher charging power is possible, but the charging system is limited by the current parameters of the commercial available battery cells. TRIALS TO BEGIN THIS YEAR IN THE CZECH REPUBLIC Development and implementation are planned for the beginning in the Czech Republic in the summer 2018. The plan is to install five superfast chargers at selected airports, but the project team is willing to discuss with any potential clients who would like to fly cleaner at lower cost. Like similar electric airplane projects, flight schools have significant potential interest in such end-to-end electric airplane solution. The cost of the system will be divided into two parts, the airplane and the charger setup. As expected, the purchase price of electric Phoenix will be higher than the model with internal combustion engine, but Pure Flight team claims that the price is going to be competitive due to its lower building cost. The charging system price will depend on the selected specification and local conditions. 4 The electric Phoenix will use a 60 KW engine and have two hours of flight time. e Flight Journal 35
