Drive reflector for projectile for RAM accelerator - comprises projectile accelerated in accelerator comprising tubular pre-accelerator, followed by accelerator tubes based on RAM effect.

摘要

The sliding drive reflector (16) on its periphery has sealing means, which have contact with the inner wall of the pre-accelerator and are so formed that they can transmit the thrust developed by the pre-accelerator to the projectile. They can release from the projectile when the latter after firing is located between the downstream end of the pre-accelerator and the entry to the acceleration tubes. The drive reflector comprises an outer ring (18) which is so formed that it can be fixed to ribs or radial guide stabiliser fins (13) to the rear of the projectile. It can carry the peripheral sealing means and a rear low-calibre disc which is so formed that it on its periphery locates on the outer ring (18), and possibly in the central area on the rear (7) of the projectile (11), and at a suitable time point is sepd from the projectile (11) and the outer ring (18). USE/ADVANTAGE - As a drive reflector for a projectile for a RAM accelerator. The drive reflector is of low wt and is of low cost, being simple in structure and use, and is suitable for an optimal operation of a RAM accelerator.
