DASS GNX
Turbo-Ramjet Cycle Engine
The DASS GNX is a precooled, air-breathing, turbo-ramjet designed to meet the demands of hypersonic flight and will ultimately become the heart of both the HELLO-1 and HELLO-2 flight vehicles. Operating as an afterburning turbojet from zero to Mach 3 and a ramjet from Mach 3 to Mach 5. The DASS GNX also features a precooler designed to significantly enhance thrust in turbojet mode and extend the operating range of the engine.
Engine Operation: Pre-cooled afterburning turbo-ramjet
