Definitions
- a training projectile embodying the invention has its center of gravity far forward in the body of the projectile and carries, at its rear end, a slotted flared tail piece which provides the desired stability and drag in flight.
- Fig. 1 is a perspective view of the invention and Fig. 2 is a plan view of a portion of the device of Fig. 1.
- a training projectile 10 embodying the invention includes a main body portion 20 which is generally cylindrical in form and has a generally conical nose portion 30 and a tail portion 40 including a downwardly tapering portion 50, a short cylindrical portion 60 and a flared tail piece 70.
- the flared tail piece 70 tapers outwardly from a small diameter to a larger diameter and the large diameter end has a plurality of generally rectangular slots 80 disposed about its surface. As illustrated in Fig. 2, the slots 80 are preferably disposed at a small angle to the longitudinal line (shown dashed) which runs through each along the wall of the flared tail piece. This angle, in one embodiment of the invention, is one degree.
- the center of gravity of the projectile 10 is as close to the nose cone 30 as possible and this is achieved by having the nose and perhaps one fourth or one third of the body made of steel or another relatively heavy weight material and the remainder of the projectile made of aluminum, or another relatively lightweight material about 3/4" thick.
- the projectile had a length of about 660mm, the main body 20 had a diameter of about 80mm, and the center of gravity was about 200 to 250 mm from the tip of the nose.
- the flare tail piece 70 In operation of a projectile 10 embodying the invention, with the center of gravity near the front of the projectile, the flare tail piece 70 provides great stability and a favorable drag which limits the operating range of the projectile, as desired.
