DARPA and the US Air Force have started the High Mach Gas Turbine (HMGT) program to develop reusable hypersonic planes. The core technology revolves around Turbine Based Combined Cycle (TBCC) propulsion systems, which integrate turbine engines for low-to-mid speeds with airbreathing components or hypersonic mach 5+ speeds. Engine Architecture and Subsystems: Development of a complete ... Read more
