Aeroengines — Performance and Speed Increase as Impetus for Development

Apart from the fundamental research activities in aerodynamics, engine development was a decisive area of work. The science of heat engines was at the beginning of the aircraft engineering no longer young, but the requirements regarding a very much improved weight/ power ratio or the improvement of the altitude capability of fast rotating Otto and Diesel engines represented a considerable challenge. As regards the test facilities, new ground had to be broken. * see Volume 2 “Flugmotoren und Strahltriebwerke” (Die deutsche Luftfahrt)
