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 ...

The secretive SR-72 “Darkstar” is Lockheed Martin’s ambitious project to build a Mach 6+ hypersonic ISR and strike aircraft. ...

This works so well that one of the key engineering problems of such engines is to design the air inlet to slow down the incoming air to subsonic speed before it heats so much that it melts the engine.

Just a couple of decades ago, aviation had some rules. If you wanted to fly fast within the atmosphere, you used a jet engine. The champion here was the SR-71 Blackbird, designed by Lockheed Martin, ...

Will DeVerter, a graduate research assistant in the Purdue Applied Research Institute’s Hypersonics Advanced Manufacturing Technology Center (HAMTC), prepares his team’s 3D printed scramjet for ...

Supersonic combustion and scramjet engine dynamics represent a frontier in aerospace propulsion, offering a pathway to ultra‐high-speed flight through the efficient combustion of fuel in a supersonic ...
