The French defense procurement agency (DGA) announced that startup AndroMach has completed qualification testing of its Banger rocket engine at the DGA Missile Test Center in Gironde. The engine achieved 21 zero-failure ignitions and a cumulative burn time of 7 minutes, successfully demonstrating reusability. Using cryogenic liquid oxygen/propane propellant, the engine powers the "Envol" hypersonic suborbital UAV. Manufactured via metal 3D printing, the engine features complex internal geometries, reducing design iteration cycles from months to weeks. The 4-meter-long Envol vehicle, with a payload capacity of about 30 kg, takes off from a runway, ignites mid-air to accelerate to Mach 5, climbs to an altitude of 200 km, and glides back for landing. This technology supports microgravity experiments, flight technology testing, and serves as a complex trajectory target for evaluating air defense systems. The Envol demonstrator is scheduled for its first flight in 2026-2027.
