Most Efficient Rocket Engine Ever Flown Will Enable Affordable Mach 9 Hypersonic Speed

Venus Aerospace has made the most efficient rocket engines ever flown. They will go from runway to mach 9 hypersonic speed. The Venus Aerospace Stargazer M4 is designed to reach a top speed of Mach 9, which is approximately 6,900 mph. While its cruise speed is planned to be around Mach 4-5, the engine combination …

Venus Aerospace Hypersonic Engine Breakthroughs

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 call the Venus Detonation Ramjet (VDR2). This will enable hypersonic flight (up to Mach 6-10) from conventional runways, with emphasis on efficiency, challenges, and innovations. It could also …

Historic Aviation Engine Advance to Unlock Hypersonic Mach 10 Planes

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) over traditional deflagrative engines. They could potential provide for 25-30% or more efficiency when hybridized with air-breathing systems for hypersonic applications. A past gain of 15-30% gain …

Venus Aerospace Has First High Thrust Rotating Detonation Engine Flight

On May 14, 2025 Venus Aerospace became the first in the world to successfully fly a high-thrust rotating detonation rocket engine (RDRE) — achieving what no government or private entity had done before. The RDRE utilizes supersonic detonations in a circular chamber to achieve higher thrust-to-weight ratios and greater fuel efficiency (theoretically up to 15% …

First Flight of Venus Aerospace BREAKTHROUGH Rotating Detonating Engine

Venus Aerospace had the first-ever U.S. flight test of a rotating detonation rocket engine (RDRE)—a next-gen propulsion technology that’s been theorized for decades, but never flown… until now. The Rotating Detonation Rocket Engine (RDRE) changes everything, and Venus is the first venture-backed aerospace company to bring the RDRE from concept to commercialization. RDREs are a …
