Abstract

Designing of modern liquid propellant rocket engines (LPRM) is impossible without generalization of an experimental material on instability of working process in the combustion chambers, accumulated as a result of firing tests of full-scale and modelling products. The present article is section of such generalization, in it (her) ways of elimination high-frequency oscillations of pressure of gas in combustion chambers LPRM and increases of a reserve of dynamic stability(immunity) of chambers are considered(examined) due to design features of mixing heads.

Keywords:

LPRM, the combustion chamber, injectors, mixing the head, high-frequency oscillations, acoustic absorbers (absorbents), an impedance
