Abstract (en)
An improved self-ablative fin assembly for a cannon-fired high velocity munition projectile having an aerodynamic nose, a selectively elongated intermediate body rearward of the nose and a plurality of stabilizing fins attached to the rear portion of the body which prevents thermal degradation and abrasion of the fins during shell firing and projectile flight. The fin assembly consists substantially of a heat resistant, low friction, self-ablative polyetheretherketone polymer material which forms a protective ablative char when overheated in air.
