  • Solid propellant charges
    Patent number: 4004523
    Abstract: A solid propellant charge having combustion inhibited surfaces provided by bonding elastomeric combustion-inhibiting material to the surfaces by a layer of a polyvinyl acetal resin bonded directly to those surfaces, and by a layer of another resin selected from epoxy resins, polyesters and formaldehyde resins.
    Type: Grant
    Filed: October 26, 1966
    Date of Patent: January 25, 1977
    Inventors: David Victor Clifford, Stephen William Bell, Stuart Gordon, Philip Graham Jones
  • Solid propellant with inhibitor layer in rocket motor
    Patent number: 3991565
    Abstract: 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.
