Spin-stabilized training missile
First Claim
1. A spin-stabilized training missile which comprises a base member shaped as a missile with a stabilizer means for reducing spin in order to decrease the flight range, the base member of the training missile, upon firing, having a stability due to spin that is too low for stable flight, and said stabilizer means comprises at least one element having a stabilizer surface which effects, on the one hand, an additional aerodynamic stabilization providing stable flight in the training range together with the spin stabilization of te base member and, on the other hand, after leaving the training range, such a spin reduction that the training missile becomes unstable;
- the stabilization attainable by spin upon firing of the training missile base member, without the stabilizer means, is defined by a stability factor s<
1, said stabilizer means, which is mounted behind the center of gravity of said base member, initially compensating for the lack of stability of the base member and then generating a longitudinal moment which brakes the rotation of said training missile.

Abstract
A spin-stabilized training missile is equipped with a stabilizer device for reducing spinning in order to decrease the flight range. The training missile is designed so that its stabilization attainable solely by the spin upon firing is not sufficient for a stable flight in the practice range. The required additional stabilizing in the practice range is obtained by a stabilizer device or control airfoil effecting simultaneously, after leaving the practice range, such a spin reduction that the training missile becomes unstable and the range of flight is controlled.

14. A training missile comprises a base member shaped as a missile with a stabilizer means for reducing spin in order to decrease the flight range, the base member of the training missile, upon firing, having a stability due to spin that is too low for stable flight, and said stabilizer means comprises at least one element having a stabilizer surface which effects, on the one hand, an additional aerodynamic stabilization providing stable flight in the training range together with the spin stabilization of the base member and, on the other hand, after leaving the training range, such a spin reduction that the training missile becomes unstable, the adjustment angle of the stabilizer surface of the at least one element of the stabilizer means being selected to be equal to the geometric angle of incidence α
- geom on the training flight path whereby the stabilizer means initially exerts a longitudinal moment on the training missile accelerating the rotation thereof and thereafter exerts a braking longitudinal moment on the training missile thereby reducing the rotation.
