NASA previously funded a Lockheed Martin study that found speeds up to Mach 7 could be achieved with a dual-mode engine combining turbine and ramjet technologies. The problem with hypersonic propulsion has always been the gap between the highest speed capabilities of a turbojet, from around Mach 2.2 to the lowest speed of a scramjet at Mach 4. Typical turbine engines cannot achieve high enough speeds for a scramjet to take over and continue accelerating. The NASA-Lockheed Martin study is looking at the possibility of a higher-speed turbine engine or a scramjet that can function in a turbine engine's slower flight envelope; the <a href="/wiki/DARPA_HTV-3X" class="mw-redirect" title="DARPA HTV-3X">DARPA HTV-3X</a> had demonstrated a low-speed ramjet (Dual Mode Ramjet) that could operate below Mach 3.
