Turbine housing turbopump assembly of liquid rocket engines

摘要

The invention relates to the field of rocket engine and in particular to the housing of the turbine of the turbopump unit liquid-propellant rocket engines (LRE).; Turbine casing of the turbopump unit LRE consists of a stator and a collector which are rigidly secured together, wherein the stator comprises a housing and a nozzle device with guide vanes, and the collector comprises a body formed as a curved pipe, made of two identical stamped halves welded together , wherein on the inner surfaces of the stator casing and the collector - flow section of the turbine - a layer cermet coating, wherein the stator housing and the collector-metal formed llicheskimi heat resistant nickel alloy HN58MBYUD and the thickness of the layer cermet coating on the inner surfaces of the stator housing and the collector is between 50 microns to 300 microns.; The most successfully claimed utility model may be used in rocket engineering, primarily in the LRE turbopump unit and turbines which work on the oxidative gasification gas.
