IDEAL JET COMBINATION ENGINES

摘要

At present time we have two types of jet engines;ramjet engine (PVRD) and rocket engine RkD). In the first one the source of the working body appears to be the atmosphere. in the second the entire supply of working body is shifted together with the engine. The differences in the conditions of obtaining the work¬ing body create vertain characteristics even in the occurrence of the working process in these engines, and they in turn exerts a greater influence on the possibility of employing these engines.
