New hybrid engine for aircraft to use compressed air

The Scuderi Group has secured patents for the world’s first air-hybrid internal combustion aircraft engine, which promises to increase the fuel efficiency of today’s propeller-equipped airplanes and reduce toxic emissions by up to 80 percent - with a design that the company claims will make air-hybrid prop airplanes lighter and less expensive to build.

Scuderi developed a split-cycle technology to recapture and store energy in the form of compressed air.

Unlike conventional airplane prop engines, the Scuderi engine produces compressed air during its normal operation.

By adding a small air storage tank with simple controls costing only a few hundred dollars, the Scuderi Air Hybrid Airplane Engine can apparently recapture energy normally lost during cruising and deacceleration at landings.

An external charging capability gives the airplane more runway flexibility, providing a boost of power for shorter take offs. The inherent supercharging can also increase the range and altitude of the aircraft, ultimately providing longer cruising distances.

“This design gives the airline industry its first hybrid alternative, enabling airplane engine manufacturers to incorporate significant savings and fuel efficiency into their airplanes,” said Sal Scuderi, president of the Scuderi Group.

The company claims its engine will significantly increase the range or altitude of an average propeller-driven airplane and improve power and performance. Today’s electric hybrid vehicle engines normally reduce power and performance to obtain an increase in mileage.

Currently under development, the first air-hybrid engine prototypes are expected to be completed in 2007.

Backed by the U.S. government, Scuderi says its engine is also adaptable to diesel and gasoline automobiles, commercial vehicles and any other applications powered by internal combustion engines. The company plans to license its technology to qualified engine manufacturers.
