FIELD: astronautics.
SUBSTANCE: invention relates to rocket engineering. Combustion chamber with cross-section close to rectangular, consisting of mixing head with anti-pulsation baffle and chamber housing with section at the head, having expansion angle, according to invention antipulse baffle consists of parts made at angles to chamber walls. Anti-pulsation partition is made hollow and is connected on one side to the inlet header, and on the other side - to the header communicated with the mixing chamber of the mixing head.
EFFECT: invention provides suppression of transverse modes of high-frequency pressure fluctuations in combustion chamber with cross-section close to rectangular one.
