Flight Design GmbH will debut a hybrid engine concept for light aircraft at the upcoming Aero show in Friedrichshafen, Germany (2-5 April). Flight Design developed the concept engine over the past two years with Franz Aircraft Engines.
The concept is based on a Rotax aircraft engine together with an electric booster. The very high boost power of the electric motor is only used for take-off and climb.
The result is an optimized engine in respect to size, weight and fuel efficiency for cruise flight, with additional 40 horsepower for take-off, climb or during an engine stoppage due to fuel starvation.—Matthias Betsch, Flight Design CEO
Due to of the low installed system weight, the propulsion system will give new possibilities for general aviation airplanes by increasing payload. First flight tests of the new powerplant system will be made in 2009 using an existing airplane. Flight Design also indicated that preliminary talks with the EASA regarding certification have been already successfully conducted.
Flight Design is a 23-year-old air sport products producer based in Germany. More than 1,300 of its aircraft are flying in 25 countries. One of the first aircraft certified under the American ASTM standards, in 2005, the CT (“composite technology”) remains the best-selling LSA in America through four consecutive years. CT in several models has been popular in Germany and Europe for more than thirteen years.
