    Story by Michael Weber 

    Air Force Research Laboratory

    On October 14, 1947, The Bell X-1 aircraft was the first to achieve a speed of Mach 1 in level flight. The X-1 was powered by the XLR11 rocket engine. The X-15 was the first manned, hypersonic rocket plane that could reach speeds above 4,500 mph (Mach 6.7). The Air Force Rocket Propulsion Lab (a precursor to the AFRL Rocket Lab) developed the XLR11 and XLR99 liquid rocket engines, as well as other technologies used for these amazing air/spacecrafts. For flight in the thin air outside of the earth's atmosphere, the X-15 used a reaction control system (RCS) which was initially tested on the X-1B. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control while those on the wings provided roll control. The knowledge gained from the X-15 program provided data that paved the way for spaceflight programs such as the space shuttle. A similar reaction control system developed for the X-15 is now used on nearly every satellite sent into orbit today.
