A new hybrid rocket engine combining a Rotating Detonation Engine (RDE) with an aerospike nozzle could finally make Single-Stage-to-Orbit a reality — and it was designed by A.I. For decades, the aerospike engine was considered too complex to build. Unlike a conventional bell nozzle, the aerospike automatically adjusts to ambient pressure at any altitude, making it far more efficient from sea level all the way to space. The challenge was always manufacturing and thermal management — until now .In this video, we look at how generative design tools like LEAP 71's Noyron, combined with 3D metal printing, are solving problems that grounded NASA's X-33 program in the 1990s. These AI-driven computational engineering models can design internal cooling channels and variable porosity structures that no human engineer could draw by hand. The Rotating Detonation Engine adds another layer — instead of conventional combustion, it uses controlled supersonic detonations propagating through an annular chamber, producing up to 25% more thrust than a traditional rocket propulsion system. Paired with methane as a fuel source and advanced composite tanks, the weight and density challenges that killed previous SSTO concepts are now solvable. Astrobotic recently ran a 4,000 lb thrust RDE-Aerospike prototype for over 300 continuous seconds — a record. This is no longer theoretical. How rocket engines work has fundamentally changed. The combination of aerospike nozzle design, generative AI, and 3D printing may be the most game changing development in chemical rocketry in decades.
