Abstract
Abstract A composite or modified double base propellant that is reinforced with a substrate material and suspended in a rocket motor case from the head end of the propellant by bonding the propellant to the motor case. The substrate material is fabricated into the propellant composition by being incorporated in a carpet roll fabrication. Applicant''s reinforced propellant is therefore applicable for use in a high pressure, short duration eject motor which requires a high acceleration load capability.
