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 ...
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.

The reaction control system uses thrusters at the aircraft extremities, nose, tail and wingtips. Thrust from the engine can be temporarily syphoned to control the aircraft's pitch, roll and yaw before it is going fast enough for the elevators, rudder and ailerons to become effective. [40]
Bell designed and built the Reaction Control system for Project Mercury's Redstone command module and a similar system was incorporated into the North American X-15 spaceplane. NASA selected Bell to develop and built the Lunar Landing Research Vehicle (LLRV) , three of which were built in the early 1960s to train the Apollo astronauts to land ...
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]
After the aircraft was secured vertically, the trailer was lowered to horizontal and then used to transport the aircraft on the ground. Pitch and yaw control in hover were provided by vectored engine thrust. Roll control was provided by "puffer" jets (also known as "jet reaction control") mounted outboard of the wingtip endplates.
A reaction control thruster (RCT) system, similar to that on orbiting spacecraft, was also installed to obtain research data about their effectiveness for vehicle control. As the M2-F3's portion of the lifting body program neared an end, it evaluated a rate command augmentation control system, and a side control stick similar to side-stick ...
