A jet engine is any engine that can propel an aircraft of some kind via rearward expulsion of a jet of fluid, typically a hot exhaust gas that the engine generates by drawing in fuel from the ...

Ramjet engines make it possible to reach very high flight speeds of more than five times the speed of sound, known as hypersonic. These engines not only offer great potential for future aviation and ...

This engine combines: A turbojet for lower speeds (e.g., takeoff and landing). A ramjet for high-speed flight, enabling the transition to hypersonic velocities. For the 2025 flight, the Quarterhorse ...

The company revealed that scientists at its Global Research Center in upstate New York successfully tested a dual-mode ramjet engine subscale demonstrator that used rotating detonation combustion.

This has the potential to reduce the overall weight of the engine as well as shortening the length of a combustion module in a dual-mode ramjet (DMRJ) or turbine-based combined cycle (TBCC).

Can we keep getting faster and faster without hitting a big gap? Can the engines be light enough? Venus Aerospace has developed the Venus Detonation Ramjet 2000 lb Thrust Engine (VDR2), which ...
