Prediction markets are facing backlash over bets related to war, with Polymarket recently archiving some predictions on nuclear detonation.

Directly testing how stiffness and wave propagation govern these differences has been difficult in live animals and prior robotic models. To address this challenge, the PKU team developed a ...

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed Martin and General Electric could help it catch up. The United States is ...

The rotating detonation ramjet engine provides a more compact, lightweight design than standard engine designs, and uses a continuous, self-sustaining detonation wave. GE Aerospace and Lockheed Martin ...

When your car starts making a metallic knocking sound under the hood, you'd assume it could only be one thing: the engine. However, there are two common culprits, and they're definitely not the same.

Abstract: In both military and civilian fields, cloud detonation or similar gas explosion accidents involve the special energy release process of gas-phase detonation. This type of gas-phase ...

Andrew Duggleby, co-founder and CTO of Venus Aerospace, discusses their groundbreaking propulsion technology. They have a ramjet integrated with a rotating detonation rocket engine (RDRE) which they ...

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...

Abstract: A series of numerical simulations of rotating detonation combustor with different plenum length are performed in this paper. The effect of plenum length on propagation characteristics of ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...
