FIELD: ramjet engines. SUBSTANCE: device to inject fuel into ramjet engine of aircraft flying at supersonic or hypersonic speed of flight is intended to function in wide range of speeds. Ramjet engine has outlet unit 3 for oxidizer, combustion chamber 5 and thrust nozzle 6 meant to remove gases coming from combustion chamber to atmosphere placed along current. Device to inject fuel has at least one injector 7 which structure includes assemblage of partitions 8 placed at some distance from each other and along longitudinal axis X-X of housing of given ramjet engine. Fuel can be injected on one hand in each space 9 formed by two adjacent partitions 8 from mentioned assemblage of partitions and on the other hand in rear free end of mentioned injector 7. EFFECT: improved reliability of control over various combustion conditions. 5 cl, 8 dwg
