The demon of engine knock is something an owner of a traditional high-performance Pontiac knows all too well. An engine designed when 102-octane high test was at almost every fuel station in the ...

GE and Lockheed Martin plan to get around this by accelerating the missile using a rotating detonation engine, which uses a supersonic wave of detonating fuel that runs about inside an open-ended ...

Engine knocking, or detonation, occurs when fuel in the cylinders ignites unevenly, causing metallic pinging sounds, reduced power, and potential engine damage. Key causes include low-octane fuel, ...

Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

Venus Aerospace, making hypersonic flight a reality for commercial and defense purposes, has achieved the first long-duration engine test of their Rotating Detonation Rocket Engine (RDRE) in ...

The rotating detonation rocket engine (RDRE) is the new Holy Grail of the aerospace industry. The way such a technology works promises unprecedented speeds for aircraft and spacecraft, prompting ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed ...

IAN Alpha Fund on Wednesday said it has invested Rs 25 crore in D-Propulse Aerospace. The firm plans to use the seed capital ...

I assume that if the detonation/flame front is itself rotating within the combustion chamber/channel/however one chooses to contain and direct it, then the expanding shockwave from the exhaust plume ...

A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace's aircraft does go supersonic on a later date, it will be ...

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...
