Venus Aerospace Accelerates Mass Production of 3D-Printed Rotating Detonation Rocket Engines
2026-07-09
U.S. space propulsion company Venus Aerospace has completed a $91 million Series B funding round, led by Mercury Fund with participation from Lockheed Martin Ventures and others. In May 2025, the company achieved the world’s first flight test of a high-thrust rotating detonation rocket engine. Unlike traditional rocket engines, the RDRE operates using a continuously rotating supersonic detonation wave within the combustion chamber, offering a 15% improvement in efficiency. The engine is made from 3D-printed components and standard materials. According to the company’s COO, the engine body consists of just three parts, which can be produced in approximately two weeks through machining and 3D printing, effectively enabling their propulsion system to reach the production scale required for defense programs.

Venus Aerospace加速3D打印旋转爆震火箭发动机量产
美国航天推进技术公司Venus Aerospace完成9100万美元B轮融资，由Mercury Fund领投，洛克希德·马丁风险投资等参投。公司于2025年5月完成全球首例高推力旋转爆震火箭发动机飞行测试。与传统火箭发动机不同，RDRE利用燃烧室内持续旋转的超音速爆震波工作，效率较传统火箭发动机提升15%。发动机由3D打印部件和标准材料制成。公司COO表示，发动机主体仅由三个部件组成，通过机加工和3D打印约需两周完成生产，正有效推进其推进系统达到国防项目所需量产规模。
