Abstract : This patent discloses a rocket motor insulator of varied thickness with an integrated flap to reduce propellant stresses. An object of this patent is to develop an improved manufacturing process for rocket motor insulation. A future object is to develop an insulation with improved thermal resistance and insulative qualities. These and other objects have been demonstrated where an ethylene propylene diene monomer based compounded rubber material is manufactured into rocket motor insulation by a 'lay up and grind method'.
