FIELD: aviation and space engineering; creation of thrust force for rocket engines. SUBSTANCE: working medium from reservoir is directed to chamber where it is heated. When working medium escapes from chamber, it is acted on by control flow of additional component, for example from additional reservoir; additional component may be heated. Control flow of additional component is fed to area beyond the chamber and external medium volume is formed to which working flows. Static pressure of control flow in this area is lesser than total pressure of working medium by 1 to 20 percent. EFFECT: enhanced efficiency. 1 dwg
