A method of inhibiting combustion of some of the surfaces of a solid propellant charge for or in a rocket motor comprising bonding to said surfaces an elastomeric compound resistant to permeation by combustible components of the charge, and bonding a combustion inhibiting cellulosic derivative to the elastomeric compound, the cellulosic derivative being spaced from said surfaces by the elastomeric compound. The invention also relates to a rocket motor provided with a solid propellant charge inhibited in accordance with the method.

Solid propellant with inhibitor layer in rocket motor

A method of suppressing unstable burning in a solid propellant rocket motor comprising combusting a silicone elastomer with burning of the solid propellant to produce a continuous stream of small silica particles which suppress instability.
