The Study of Crack Criticality in Solid Rocket Motors
Abstract
Assuming that burning in cracks and debonds in solid propellant grains will occur, the present paper analyzes the pressure distributions in these flaws during the burning process. A preliminary analysis of fracture propagation is included by which estimates of initial flaw propagation velocity are made. It is shown that varieties of flaws can exist where the pressure loading within the flaw may be sufficient to cause mechanical propagation velocities in excess of the burning rate.
