UNSTEADY COMBUSTION OF SOLID-PROPELLANTS SUBJECT TO DYNAMIC EXTERNAL RADIANT HEATING

A theoretical and experimental investigation is conducted on the effec t of a dynamic external radiant heat flux on the combustion of energet ic materials. These studies have illustrated the need for including th e effect of the mean radiant heat flux and in-depth absorption. Also, a method for obtaining the linear frequency response function over a r ange of frequencies from a single test using series of radiant pulses is demonstrated. Experimental results have been obtained for an AP/HTP B propellant.
