00:00Welcome to the video from the Car Magazine Tuning Blog.
00:03Today we're talking about a fascinating topic from aviation.
00:07A new type of rocket engine that could make it possible to fly from Los Angeles to Tokyo in under 2 hours in the future.
00:14At present, this journey takes around 12 hours.
00:18But the US company Wienes from Houston is working on a solution that could change that.
00:22For 5 years, the company has been researching a revolutionary propulsion concept that combines a rotary detonation engine, RDRE and Ramjet engine.
00:36Both technologies require no moving parts and are designed to enable speeds of up to Mach 6 or around 7,400 km per hour.
00:44What's special about it is that the propulsion system is designed to be able to power not only rockets, but also passenger and cargo aircraft, and from a conventional runway.
00:55The principle behind it is that the RDRE initially accelerates an aircraft before the Ramjet engine takes over in the hypersonic range.
01:03As early as October 2024, the first prototype, the VDR-2, was presented, which is intended to implement exactly this concept.
01:11The first test run on the ground took place in December of the same year.
01:18In May 2025, Venus announced that it had successfully conducted the world's first flight of a US-designed RDRE at Spaceport America in New Mexico.
01:29No details on duration, speed, or altitude were released, but according to Venus, the test worked under real-world conditions, which paves the way for the next step.
01:38Comprehensive tests on a full-scale scale and the integration of the engine into various types of aircraft, possibly also on behalf of government agencies.
01:47The long-term goal is a hypersonic aircraft called the Stargazer M4, which is to fly at Mach 4, or around 4,900 kilometers per hour, and carry around 12 passengers.
02:02The maximum range is around 8,000 kilometers, which is just enough to cover the distance between Los Angeles and Tokyo.
02:09Although Venus believes that a first flight is possible in the 2030s, this forecast seems ambitious given the complexity of aviation technology.
02:22Nevertheless, major names such as Airbus, NASA, and the US Air Force are already investing, indicating serious potential.
02:30Whether the stargazer will actually become a reality remains to be seen.
02:36But Venus has reached an important milestone with the successful flight test.
