Editing Combustion chamber

The '''combustion chamber''' is the part of a [[rocket engine]], where the [[Propellant|propellants]] react to [[exhaust]] gases. The length of the combustion chamber is defined by the distance, the exhaust gases have to travel until all [[w:exothermic|exothermic]] reactions took place. The combustion chamber sits between [[injector]] and [[throat]]. 

One important measure of performance of a rocket engine is the [[chamber pressure]]. The higher the maximal chamber pressure, the more fuel can get injected into the chamber at once compare to a chamber of the same size. Also, it allows a higher [[expansion ratio]] of the following nozzle, which improves performance. 

Rocket chambers are often regeneratively or film cooled, as they are the region of the highest temperatures.
