Abstract

The article discusses the design and purpose of a turbopump unit, in particular the pump housing of a turbopump unit of a liquid rocket engine. A device and a tool for obtaining complex profile holes in the housings of turbopump units are presented. The features of the design of techno-logical equipment for electrical discharge machining are considered. The proposed progressive design of the device and tool made it possible to process the parts of the turbopump unit of a liquid rocket engine with special holes.
