STAND LIQUID ROCKET ENGINE WITH CONTINUOUS SPIN DETONATION Russian patent published in 2018 - IPC F02K9/52 F02K7/02 

FIELD: test technology.

SUBSTANCE: invention relates to the field of testing, in particular, bench tests of the modes of operation of LRE operating in continuous detonation mode on a fuel mixture consisting of gaseous oxygen and kerosene. Invention is a bench LRE with an annular detonation combustion chamber, a mixing head, an initiator, a jet nozzle and measuring equipment. Distinctive features of the declared LRE is that the mixing head is made in the form of an annular gap in the firing base for the supply of oxidant, on both sides of which the fuel supply nozzles are located at an acute angle. Another difference from the known solutions is that the motor housing and the chamber are made of two layers, the inner layer is made of a strong alloy, and the outer one is made of a highly heat-conducting alloy.

EFFECT: invention provides an increase in the maximum working pressure.
