Astro Mechanica outlines 2026 ground-testing plans for its hybrid-electric supersonic engine
60 FOMOAstro Mechanica outlined its plans to take its hybrid-electric Duality propulsion system into high-altitude and high-speed ground testing during 2026. The demonstrator uses a GE CT7 turbofan connected to an electrical generator that powers two propulsors. The company was also targeting flight testing in 2027 using a purpose-designed propulsion testbed aircraft. The program represents an important transition from engine architecture development toward integrated hardware testing.
Why it matters
The planned testing campaign is a key technical validation milestone for the Duality architecture. Demonstrating stable operation across a broad speed range will be essential before the company can credibly advance toward a supersonic aircraft.
