Pyrolytic graphite in construction of missile rocket nozzle

In the article the results of works, made in Military Institute of Armament Technology, connected with a pyrolytic graphite in the nozzle construction of the solid propellant rocket are presented. The conditions of the obtaining of the high-temperature pyrolysis of hydrocarbons in order to achieve of pyrolytic graphite are presented. The erosion En of the critical diameter in the different kinds of nozzles is showed. Technological and constructional conditions of obtaining of the nozzles saturated with pyrolytic graphite, of the composite nozzles and of the nozzle elements are presented.
