Definitions

  • the steering tube has substantially the same shape as the already described steering tubes apart from the fact, that the six bottom flaps 27 have a thickness which is increasing towards the center.
  • a rearwardly directed tube 28 threaded into the rear end of the projectile, the outer mantle surface of said tube 28 forming a sliding and steering surface for a cup-shaped, rearwardly displaceable piston 29, which has a rearwardly directed, convex surface, and is provided with an opening of the same diameter as the tube 28.
  • the rear end of the tube 28 is provided with a flange 30 which serves as a stopper for the piston 29 when the latter is displaced backwards.
  • the tube 28 is provided with an annular recess 32 in which an annular spring 33 is located.
