It is expected that such an engine will be 15% more efficient than a conventional one.
Venus Aerospace, a company collaborating with the US Defense Advanced Research Projects Agency, showed a prototype of a rotating detonation engine. During the recording of the video, the device passed the long-term operation test.
And here's another story
In the future, such engines can replace conventional jet engines. In theory, rotating detonation engines are 15% more efficient than conventional engines: this will reduce fuel consumption and increase flight range.
The current test is the first time a Venus Aerospace engine has been run continuously for an extended period of time. Previously, the engine was tested with short starts; however, the device was not additionally cooled between runs.
During operation, the engine generates a series of shock waves, the source of which are controlled explosions. The engine itself does not rotate, but two coaxial cylinders rotate, between which a mixture of oxidizer and rocket fuel is supplied.
It is expected that such engines will be used both in spacecraft and, for example, in hypersonic rockets or more energy-efficient aircraft.
