Abstract
The coupled and the uncoupled effects of the ignition delay and the unsteady combustion gas temperature on ignition peak of high velocity transient motors are examined with the help of a two dimensional Navier-Stokes solver. It has been observed through the parametric studies that the altered variation of the ignition delay will alter the transient temperature growth history and the flame spread mechanism, which in turn alter the pressure spike of identical solid rockets. It has been inferred that the altered variation of both the chamber pressure-rise rate and the ignition temperature will alter the ignition delay and thereby the overall starting transient history of solid rockets. It has been concluded that the solid rocket motor designers should have a bearing on the pressure and pressurization rate prior to ignition for achieving repeatability of starting transient history in solid motors with the same propellant formulation and geometry. © 2002 by the American Institute of Aeronautics and Astronautics, Inc.
