FEATURES OF DEVELOPMENT OF OXIDIZER-RICH PREBURNER FOR MULTIMODE single-chamber ENGINE
The description of a design of a preburner is presented. Features of its stage-by-stage development with use of results of researches of process of gas generation on modelling rig are stated. The special attention is given to maintenance of combustion stability in a preburner on a mode of deep throttelling. During development of a design various variants of injectors and downflow-injector channels have been subjected to researches. Some design-technological improvements are introduced in a developed preburner by experience of manufacturing and operation of RD180 and RD171M engines.
