It is easier to replace free-standing grains if found defective on X-ray examination or if the propellant grain has aged excessively. Cartridge-loaded grains are used in some small tactical missiles and a few medium-sized rocket motors. It is easier to inspect them and their cost of production is also lower. [Pg.297]

Free-standing isotropic pyrolytic carbon is a material of choice for solid propellant rocket nozzles. Because of its strength, hardness, and isotropic nature, it is able to withstand the mechanical erosion which is the dominant failure mechanism above 3200°C.P l... [Pg.162]

It is evident that the standing pressure wave in a rocket motor is suppressed by solid particles in the free volume of the combushon chamber. The effect of the pressure wave damping is dependent on the concentrahon of the solid parhcles, and the size of the parhcles is determined by the nature of the pressure wave, such as the frequency of the oscillation and the pressure level, as well as the properties of the combustion gases. Fig. 13.25 shows the results of combustion tests to determine the effechve mass fraction of A1 parhcles. When the propellant grain without A1 particles is burned, there is breakdown due to the combushon instability. When... [Pg.392]
