Jet engines revolutionized commercial aircraft during the 20th century. This new, small jet engine is suitable for light-sport, ultralight, and experimental aircraft, and can replace the vibrating piston engine and propeller combination as used in most sport aircraft with smooth jet power for the 21st century. However, simply miniaturizing a conventional jet engine is not enough to provide an application for private aircraft. Thrust must be sufficient, and comparable to (or greater than) that obtainable by conventional propellers. But in jet engines, thrust translates directly into heat and noise, especially rearwards of the engine nacelle. In this new engine, exhaust heat is minimized for safety to 750 degrees C, so that a suitably insulated cowling can be touched. By minimizing the heat, sound absorbers can be used so that sound output of the engine is also minimized to about 200dB or less at a measured distance from the exhaust. The resulting engine opens a new class of propulsion systems to light aircraft.

Benefits Summary

o Provides jet propulsion to light-sport, ultralight, and experimental aircraft. o Enables safe operation within 2m of personnel by reducing sound and engine temperature. o Offers small size, light weight, high output, low vibration. o Achieves low noise, safety, and reliability. o Replaces the conventional revolving propeller and piston engine combination with a jet engine that produces significantly less vibration. o Overcomes the problems of high heat and high noise generated by jet engines used in commercial aircraft, thus allowing jet-equipped light aircraft to operate from small airports that may be near residential areas. more
