This article briefly discussed the possibility of expanding the range of operation of ramjet engines for unmanned aerial vehicles using water injection at the inlet to the engine. Stated and justified the results of calculations to determine the required water flow to cool the working fluid to the required temperature and the influence of water injection on the parameters of the working fluid at the inlet to the engine. The results of the project will expand the range of operation of ramjet engines due to the application of materials developed in the production of aircraft gas turbine engines, and to reduce terms of creation of competitive engines for high speed aircraft by the way of target searching of their rational thermodynamic and structural-geometrical shape.
