The K' Engine
o., The 'K' engine was regarded from the first as a Russian project though
the German specialists had completed the original designs which had been
approved by the Russians with only slight modifications. In its standard
form the 'K' had fourteen Icompressor

the main
dis vantages of the 'K' engine were its length of just over i4 metres and
its weight of 1,800 kg with auxiliary equipment. Probably because of'those
two factors an alternative project employing a supersonic compressor was
developed. The testing of this variation on the 'K' was entirely in Russian
hands f the compressor.
