Abstract
The present invention uses aerodynamic heating caused by air-friction during flight of a training projectile. The training projectile includes a nose, a body and a tail section. The body has a forwardmost end secured to the nose, and a rearwardmost end secured to the tail. Air friction during flight causes deployment of “passive” shape memory alloy (SMA) aerodynamic members in an assembly to induce drag of the training projectile thereby limiting an effective range of the projectile.
