University of Central Florida heldunique tests of a rotating detonation rocket engine, the development of which began in the mid-60s. Prior to the current tests, the creation of such an engine operating on the energy of explosions was considered impossible.
Scientists from Florida used the principle of detonationa mixture of hydrogen and oxygen, in which the front of the shock wave continuously rotates at a speed of 5 Mach, which is five times the speed of sound. The early developments, which have been going on for more than 50 years, did not succeed due to the lack of effective methods of mixing the applied chemical mixtures (propellants).
In the manufacture of experimentalThe engine used copper and brass. In the future, the use of this type of engine will be able to reduce the fuel mass required for the flight, increase the environmental friendliness of emissions during fuel combustion and increase the flight range of spacecraft.
