More Information
Summary:Techniques and architecture are disclosed for a nose insert for use in a projectile. The nose insert includes a polymer nose element and a metal cap. The polymer nose element includes a rear shank portion and a tapered head portion. Disposed onto the tapered head portion of the polymer nose is the metal cap. The metal includes an outer curved portion that terminates at a forward end in a meplat. In some embodiments, the metal cap prevents deformation of the polymer nose element caused by high stagnation temperatures experienced by the projectile during flight. In some other embodiments, the metal cap includes a locking ridge. The locking ridge is disposed on an inner surface of the metal cap component and interfaces with an outer surface of the tapered head portion of the polymer nose element.
