High loading densities and flexible thrust-time histories can be obtained by incorporating circumferential slots in cylindrically perforated grain (slotted-tube motors); head-end pressure of such motors can depart markedly from predictions by conventional methods; analysis of test data and water table investigations indicated that effects are caused by aerodynamic interactions between axial port flow and radial slot flow coupled with propellant deformation near slots; analytical model of aerodynamic interaction region was constructed, and graphical technique developed; design modifications that minimize slot effect are considered.
