Underwater launching of a supercavitating projectile out of a ballistic test setup

This paper considers the investigation of high-speed motion specifically-shaped inert bodies (projectiles) in water. The main purpose is to determine peculiar properties underwater launching supercavitating projectiles out bore a test ballistic setup. Preliminary calculations inner parameters shot are per-formed for given launcher and then compared with corresponding experimental data. Examples experimentally fired shots presented. high-energy processes associated projectile released entering water described. It shown that during launching, complex gas-dynamic conditions multi-phase following release can significantly affect trajectory its further Using experi-mental calculation methods classical loading scheme an acceleration 0.5 mm long or less under conditions, it has been determined pressure at accelerator exit increases stepwise change flow start trajectory. Taking into consideration revealed peculiarities set technical specifications mass-size parameters, perspective setup designed used estimate range projectile.
