Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system. [1] Reaction control systems are capable of providing small amounts of thrust in any desired ...

Quick Reaction Alert (QRA) is state of readiness and modus operandi of air defence maintained at all hours of the day by NATO air forces. The United States usually refers to Quick Reaction Alert as 'Airspace Control Alert'. Some non-NATO countries maintain a QRA, [1] either full-time or part-time. [2] [3]
Without the main rocket engine thrust, the X-15's instruments and control surfaces remained functional, but the aircraft could not maintain altitude. As the X-15 also had to be controlled in an environment where there was too little air for aerodynamic flight control surfaces, it had a reaction control system (RCS) that used rocket thrusters. [10]
An unusual feature of the Harrier family of aircraft is their use of two types of flight control to provide pitch, roll and yaw control: conventional control surfaces for wingborne flight, and a system of reaction control valves directing jets of bleed air from the high-pressure compressor of the engine out through the extremities of the nose ...
Ryan conducted remote controlled VTOL tethered rig tests from 1947 to 1950 and a flying rig in 1951. Ryan was awarded an Air Force contract in 1953 to develop an actual flying jet-powered VTOL aircraft, which was given the designation X-13. The aircraft was designed using calculations on a REAC 100, and two prototypes were ultimately built. [2]

Three aircraft were modified from existing Lockheed F-104A Starfighter airframes, and served with the Aerospace Research Pilots School between 1963 and 1971, the modifications included a small supplementary rocket engine and a reaction control system for flight in the stratosphere.
