Abstract
A method for enhancing an aerodynamic performance of an unmanned projectile. The method including at least one of the following: (a) morphing a cross-sectional shape of the projectile after launch thereof; (b) morphing a longitudinal shape of the projectile after launch thereof; (c) bleeding a fluid at a base of the projectile during flight thereof: (d) varying a base cone angle of the projectile as a function of speed thereof; (e) deploying at least one wing from a body of the projectile after launch thereof; and (f) deploying a fin from the body of the projectile after launch thereof.
Claims3
An unmanned projectile comprising:
- an outer skin;
- at least one of a wing and fin formed from at least a portion of the outer skin;
- and
- means for deploying the at least one of the wing and fin from the skin of the projectile after launch thereof to increase an aerodynamic performance of the projectile;
- wherein the means for deploying comprises means for releasing a retention of the at least one of the wing and fin to deploy the same and the means for releasing the retention comprises a locking strip disposed on the skin and having a portion thereof which interferes with the at least one of the wing and fin to prevent its deployment and a release means for releasing the strip from interfering with the at least one of the wing and fin, the locking strip comprising a shape memory alloy.
