The engine, which is claimed to be the first of its kind, is powered by boron. The critical element is used in scramjet engines, which are supersonic combustion ramjet engines. Boron's use in new ...

MHD scramjet The MHD ramjet/scramjet has some similarities with the Skylon concept. The MHD ramjet/scramjet could use reduced heat by slowing the air down to keep the weight of the vehicle from ...

The engine design modifies a standard military turbine such as an F100 or F110 and couples it to a supersonic combustion ramjet (scramjet), using a common inlet and nozzle.

Design principles of scramjet engines Eliminating moving parts, hypersonic scramjets compress incoming air by using the already high-speed airflow available.

In a ramjet, the air is compressed, but it’s still only moving at subsonic speed as it passes through. But in a scramjet, the air is moving at supersonic speeds throughout the engine.

Unlike a ramjet, whose engine slows the internal airflow to subsonic speeds, a scramjet allows a supersonic airflow through its engine. Scramjets can reach hypersonic speeds, exceeding Mach 5.

WEST LAFAYETTE, Ind. — A team at the Purdue Applied Research Institute (PARI), the university’s research and development center, is using state-of-the-art additive-manufacturing equipment to print a ...

An experimental hypersonic jet engine has been successfully tested in flight for the first time, Australian scientists have announced. The HyShot supersonic ramjet combustion or "scramjet" engine ...

It would be capable of landing at any large airport with the aid of a turbojet engine, which would begin operating at lower speeds after the scramjet engine is shut down and bypassed.

By 3D printing their scramjet engines, they can not only iterate through design revisions faster, but produce them far cheaper than they’ve been able to in the past.

The US Air Force and Pratt & Whitney are starting tests this week on the first flight-weight, hydrocarbon-fuelled, supersonic-combustion ramjet (scramjet) engine at engineering services company ...
