They may also have one or more rocket engines , directional stabilization device(s) (such as fins , vernier engines or engine gimbals for thrust vectoring , gyroscopes ) and a structure (typically monocoque ) to hold these components together. Rockets intended for high speed atmospheric use also have an aerodynamic fairing such as a nose cone , which usually holds the payload. As well as these components, rockets can have any number of other components, such as wings ( rocketplanes ), parachutes , wheels ( rocket cars ), even, in

The main difficulties include cooling the combustion chamber, pumping the fuel (in the case of a liquid fuel), and controlling and correcting the direction of motion. Rockets consist of a propellant , a place to put propellant (such as a propellant tank ), and
759-432: A chemical reaction is initiated between the fuel and the oxidizer in the combustion chamber, and the resultant hot gases accelerate out of a rocket engine nozzle (or nozzles ) at the rearward-facing end of the rocket. The acceleration of these gases through the engine exerts force ("thrust") on the combustion chamber and nozzle, propelling the vehicle (according to Newton's Third Law ). This actually happens because

Larger rockets are normally launched from a launch pad that provides stable support until a few seconds after ignition. Due to their high exhaust velocity—2,500 to 4,500 m/s (9,000 to 16,200 km/h; 5,600 to 10,100 mph)—rockets are particularly useful when very high speeds are required, such as orbital speed at approximately 7,800 m/s (28,000 km/h; 17,000 mph). Spacecraft delivered into orbital trajectories become artificial satellites , which are used for many commercial purposes. Indeed, rockets remain
