Venus Aerospace Successfully Tests Rotating Detonation Rocket Engine

US-based propulsion company Venus Aerospace completed a short flight test of its rotating detonation rocket engine at Spaceport America, New Mexico. This marks the first US flight test of a high-thrust rotating detonation engine, a concept explored for decades. The test, using a 2,000-pound thrust engine, lasted about half a minute and didn't break the sound barrier. However, it represents a significant step towards realizing hypersonic travel and improved fuel efficiency in various applications, potentially enabling global travel in under two hours.
