The paper considers design and use of parts and assemblies of a liquid propellant rocket engine — a combustion chamber, nozzle head, nozzles. Traditional and advanced technologies for making holes of small diameter in the details of these engines are analyzed. The features of the process of drilling small holes are indicated. The advantages and disadvantages of mechanical processing of component parts and assemblies of a liquid propellant rocket engine, as well as promising methods of electron beam and laser processing are given. It has been found that it is most expedient to obtain small diameter holes in such parts by combining electroerosive and electrochemical methods. The advantages and disadvantages of the combined processing method are described. It is noted that the presented technological processes, already implemented in aerospace production, increase the productivity and accuracy of holes, as well as reduce material and labor costs for the manufacture of special equipment products.
