Authors Abstract
Content
THE author has written an addendum to his paper: “Future Research on Air-Cooled Aero Engines” delivered in July, 1935.
General prophesies are made on airplane performance, types, trends on the number of engines per airplane, engine sizes in airplanes, wing loading, and engine arrangement. His analysis of engine types to complete the desired power range indicates a definite trend toward higher powers The advantages of the use of higher octane fuels are stressed.
Mr. Fedden deplores the fact that no development work on compression-ignition aircraft engines is being done in England, and thinks that the 1500-hp. class should be tackled energetically.
The comparative qualities of various engine types are discussed.
Negative cooling drag is claimed to be possible at airplane speeds of 400 m.p.h.
The flat engine is mentioned as a possibility although its use depends on the thickness of the airplane wing.
Advice from the airplane designer is considered necessary on wing-thickness trends and other aerodynamical matters to assist in the proper selection of engine types.
