Liquid rocket fuel. Oxidizer. Pumps carry the fuel and oxidizer. The combustion chamber mixes and burns the two liquids. The hot exhaust is choked at the throat, which, among other things, dictates the amount of thrust produced. Exhaust exits the rocket.
A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines.Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight.
Rocket-powered aircraft are aircraft that are powered by rockets over part of their flight; but may also have other propulsion systems to give an extended range. Pure rocket-powered aircraft can often be considered to be rocket gliders , as they will often spend most of the flight gliding.

Opel RAK.1, world's first public flight of a rocket-powered aircraft on September 30, 1929, piloted by Fritz von Opel. During the 1920s, German daredevils and inventors had experimented with the use of solid-fuel rockets to propel various vehicles, such as cars, motorcycles, railway carriages, snow sleds, and, by 1929, aircraft such as Alexander Lippisch's Ente and Fritz von Opel's RAK.1.
