1981 Porsche Aircaft Engine
Already in 1955 there had been a Porsche aircraft engine, at that time on the basis of the 1.6-liter engine of the 356. These years, however, the pre-conditions were better, because the efficiency weight was substantially
more favorable. Of course, this is one of the most important characteristics for an aircraft engine, as it must be able to pull itself into the air. Since also the fuel consumption in relation to the power of this engine was
favorable, it was used in many new and advancedly designed airplanes.
The necessary modifications of turning a vehicle engine into an aircraft engine are considerable. Instead of the clutch, there is a transmission coupled to the flywheel, which drives the propeller and allows more than twice
the speed. In addition, it should be able to both rotate clockwise and counter-clockwise, while the crankshaft keeps its rotation direction. On the other side of the engine, two generators are inserted due to the huge power
consumption of an airplane. The blower of the vehicle engine is preserved, because the airflow cannot be led to the cylinders according to their demand. The heat exchangers in the exhaust gas pipes are preserved, too,
because especially in larger altitudes heating is required. The exhaust gas treatment may be less advanced, though.
