Flight Design <strong>and</strong> Rotax collaborated to produce this motor <strong>for</strong> this year’s Aero 2009 E-<br />
Fli Flight ht Expo. E It i is i<strong>in</strong>stalled t ll d on a CTS light li ht sport t aircraft. i ft<br />
“Flight Design GmbH, the German creators of the popular CT l<strong>in</strong>e of light sport aircraft,<br />
used AERO Friedrichshafen to announce details of their work on a new hybrid eng<strong>in</strong>e<br />
concept. The propulsion package consists of a st<strong>and</strong>ard Rotax 914 turbocharged eng<strong>in</strong>e to<br />
which is mated a 40-hp (30 kW) electric motor. The electric motor is coupled to the<br />
propeller hub us<strong>in</strong>g a poly-V-belt drive that has no overload<strong>in</strong>g impact on the crankshaft<br />
<strong>and</strong>, thus, allows the motor to transmit its power directly to the po<strong>in</strong>t where it's needed.<br />
S<strong>in</strong>ce the basic Rotax is left mostly y untouched, its 130-hp poutput, p comb<strong>in</strong>ed with the electric<br />
motor's 40 hp, provide <strong>for</strong> a comb<strong>in</strong>ed 170-hp output <strong>for</strong> the hybrid. The electric motor will<br />
be used <strong>for</strong> takeoffs <strong>and</strong> climbs, <strong>and</strong> makes use of its full capacity over a maximum fivem<strong>in</strong>ute<br />
span. In cruise, power comes entirely from runn<strong>in</strong>g the gas eng<strong>in</strong>e at full power.<br />
Twenty m<strong>in</strong>utes is required <strong>for</strong> a full recharge on the 25 kilos of lithium ion batteries that<br />
power the electric motor.<br />
“One of the features be<strong>in</strong>g touted by Flight Design is the added safety <strong>in</strong>herent with a<br />
hybrid. Should there be a failure of the combustion eng<strong>in</strong>e, power from the electric motor<br />
can supplant a stopped eng<strong>in</strong>e <strong>and</strong> provide sufficient thrust to stretch the aircraft aircraft's s glide to<br />
an emergency l<strong>and</strong><strong>in</strong>g. Flight Design expects to beg<strong>in</strong> flight test<strong>in</strong>g of its hybrid <strong>in</strong> one of<br />
its exist<strong>in</strong>g aircraft by the middle of 2009.”<br />
