A division of General Electric – GE Aerospace in others) reported testing the world’s first hypersonic two-dimensional reaction system (DMRS) using mm rotating detonation combustion (RDC) in a supersonic flow, which, according to the developers, should increase the flight range of the future. hypersonic missile.
The United States still has not “overcome” the hypersonic barrier (more than Mach 5), or more precisely, has not fully resolved the global complex of technical problems, the boundaries with the search for new materials that can withstand extreme temperatures, what are the temperatures, what is the confidentiality of the new system? Certain hypersonic forces provide the American MB with the ultimate goal of flight – a dive.
And instead of the main problem – the engine. This is a result of jet engine statistics (JE), and is unfortunately not very effective at low Mach values. To “accelerate” hypersonic vehicles, a launch vehicle is required.
GE Aerospace has rebuilt its DMRJ engine, launched today by rotating detonation combustion, where a mixture of fuel and air is forced into the space between cylinders located one inside the other. It is also widely used, forming very large-scale jets that generate a supersonic jet jet ejected through a nozzle, which creates the necessary, already “hypersonic” thrust.
One of the main advantages of the DMRJ is the simplicity of the design and the absence of driving forces, which is very important when flying at hypersonic speed. The engine prototype was demonstrated on a test bench with the GE Aerospace plant in Niskayuna, State. NY.
