Abstract

Ujawniono silnik rakietowy z wielostopniowym spalaniem mieszanki materiałów pędnych, posiadający co najmniej jedną komorę spalania wstępnego oraz główną komorę spalania, układ doprowadzania składników mieszanki materiałów pędnych do tych komór, w tym pompy paliwa i utleniacza, jak również dyszę gazów wylotowych, który według zgłoszenia ma co najmniej jedną stopniową komorę detonacyjną, obejmującą co najmniej dwie wstępne komory detonacyjne (1, 2), a na ich wylocie komorę dopalania (3), gdzie następuje pełne wymieszanie i dopalenie produktów detonacji z komór wstępnych (1, 2), zaś gazy wylotowe kierowane są na zewnątrz przez dyszę (4), korzystnie typu Aerospike. W silniku tym w indywidualnej stopniowej komorze detonacyjnej, wstępne komory detonacyjne (1, 2) są koncentryczne i mają budowę rurową, pierścieniową, dyskową, bądź stożkową i pracują w trybie detonacji wirującej, przy czym do jednej z dwu wstępnych komór detonacyjnych (1, 2) w indywidualnej stopniowej komorze detonacyjnej doprowadzana jest gazowa mieszanka o składzie przebogaconym w paliwo, a do drugiej z nich doprowadzana jest gazowa mieszanka o składzie przebogaconym w utleniacz. Rozwiązanie pozwala na zmniejszenie w porównaniu ze stanem dotychczasowym gabarytów silnika rakietowego z wielostopniowym spalaniem mieszanki materiałów pędnych, a także masy silnika.
