END-BURNING PROPELLANT GRAIN WITH AREA-ENHANCED BURNING SURFACE
摘要:
An end-burning grain of a solid rocket motor or other gas-generating device is supplemented with one or more sticks of high-burn-rate propellant embedded in a matrix of a relatively low-burn-rate propellant. The sticks increase the burning surface area as the grain burns by forming conical indentations in the surface.
