Debrief: Astro Mechanica’s Electric Supersonic Engine To Be Tested

Aviation Week reported that Astro Mechanica planned to begin high-altitude and high-speed ground testing of its hybrid-electric supersonic engine in 2026. The ground demonstrator uses a GE CT7 turbofan to drive a generator, which powers two propulsors. The company was targeting a flight demonstration in 2027 using a specially designed propulsion testbed aircraft, followed by further development of its supersonic aircraft technology.
