Solid rocket motor propellant formulations are provided which are capable of burning at at least two selected burn rates. The burn rate is controlled by controlling the pressure at which the propellant burns. For example, it is possible to mechanically modify the container, such as a rocket motor casing, in which the propellant is held in order to modify the pressure under which the propellant burns. Alternatively, the propellant may be configured or molded such that the pressure changes at a chosen time due to the process of burning the propellant. The ...
A method of burning a solid rocket motor propellant at at least two stable burn rates over at least two corresponding pressure ranges, the method comprising the steps of: formulating a solid rocket motor propellant comprising from about 6.0% to about 10% of a binder consisting essentially of hydroxyterminated polybutadiene; from about 65% to about 90% ammonium perchlorate; and from about 0.3% to about 5.0% refractory oxide selected from the group consisting of TiO2, Al2O3, SiO2, and ZrO2; and igniting said solid rocket motor propellant whereby the propel...
