A scramjet (紧急刹车) engine goes as fast as a rocket, but it doesn't have to carry its own oxygen supply. A scramjet's special design allows it to obtain oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion (...
NASA engineer Laura O'Connor inspects a supersonic ramjet (scramjet) engine model at Langley Research Center in Hampton, Virginia. © Corbis Key Takeaways A ramjet is a type of air-breathing jet engine that operates on the principle of compressing incoming air without the need for rotating...
The scramjet engine is a simple design with no moving parts. The X-43A craft itself is designed to be a part of the engine system: The front of the vehicle acts as the intake for the airflow, and the aft serves as the nozzle that accelerates the exhausted air.The scramjet engine is ...
In a First, India Launches a Hypersonic Missile Could This Quantum Tech Defeat Aircraft Jamming? Could AI Enable Would-Be Bioterrorists? AR Headsets Could Change How Soldiers Fight China’s New Stealth Fighter Is a Challenge to U.S.
A hypersonic cruise missile is boosted by a rocket to hypersonic speed and then uses an air-breathing engine called ascramjetto sustain that speed. Because they ingest air into their engines, hypersonic cruise missiles require smaller launch rockets than hypersonic glide vehicles, which means they ...
