In this paper there were presented investigations of graphite hybrid nozzles i.e. consisted of pyrographite insert - optionally larger and smaller one mounted into polycrystalline graphite body by means of adhesive. An aim of investigations, it was determination of resistance of newly designed graphite nozzles against thermo-mechanical and possible chemical impact/erosion of high speed combustion products flow as a result of burning of solid propellant sustaining charge of antiaircraft short-range missile GROM. IR thermal camera and real time rentgenography (RTR) measured thermo-mechanical erosion action of combustion products towards the graphite nozzles. Hybrid nozzle with larger pyrographite insert is able to resist combustion products erosion. So, it seems to be possible to replace currently produced pyrographite nozzles by hybrid ones equipped with larger insert. Such replacement should cause considerably decrease of mass content of relatively expensive pyrographite in construction of the nozzles, from 100 to 40 percent.
