Boattail Emergence by Ejecting Nozzle Exit Cone.

Abstract

This invention describes a device for altering the after body shape of a missile configuration so as to reduce the ballistic flight drag coefficient after booster burnout. It includes a linear shaped charge cutting device for severing a portion of a nozzle exit cone just aft of a fixed boattail configuration on the outer surface of the missile. This device allows boundary layer air flow to flow smoothly over the boattail and thereby reduce the base drag on the missile during the coast phase thereof. (Author)
