Abstract:By giving some examples, the key technology of injector head design in LRE is discussed in the paper. The number of injectors is limited on the head of LRE chambers, and the injectors always differ some what from one another with respect to their parameters due to inevitable manufacturing errors. All these will result in inhomogeneous distribution at the same section of the chamber.Some experiences drawn from the development of internal cooling ring of the chamber body are also presented.
Keywords:Liquid rocket engine   Injector   Cooling system   Film cooling
