Testing a dual-mode ramjet engine with kerosene combustion

Results of life firing tests of a dual-mode ramjet engine intended for operation in the speed range М = 3−6 are discussed. The tests were carried out on a test bench under freestream conditions typical of Mach 6 flight at 27.6-km altitude. In the tests, the adopted design and technological solutions were verified, and efficient operation of the ramjet engine with kerosene combustion during 110 s was demonstrated.
