Abstract:

This report summarizes a two-year effort on the testing and evaluation of nozzle inserts and insulation for advanced propellant-motor systems. Two series of tests were performed with a 12-inch diameter motors to evaluate blast tube liner insulation, nozzle inserts, and nozzle extension insulation. Each series was tested in a characteristic environment defined by the propellant composition. The first series of six tests was made utilizing C-518 propellant containing 17.5 aluminum the second series of five tests was made with RS-2, a nonaluminized propellant. The propellant loading for both series was intended to provide 1500 psi for 10 seconds. The C-518 propellant tests burned 1 second longer at a slightly reduced pressure the RS-2 burned for approximately 9 seconds at a higher pressure. By coparing the erosion susceptibility on a unit time basis, the values are normalized sufficiently to provide comparative results. Author
