Concept of rotation loss with reference to trailing vortex induced by flow ejected from GEM or ram wing; authors designate reduction of parasite drag "interference thrust" and propose that it must be taken into account on estimating GEM performance because of its large amount; investigation of mechanism of interference thrust may be useful to improve GEM performance or to find superior types of GEM.
