Abstract

Et prosjektil (50) drives fra et punkt i luft gjennom et luft/vanngrensesnitt og mot et undervannsobjekt (24). Prosjektilet (50) har en forreste ende (52) som skaper et kavitasjonshulrom (30) nmdt prosjektilet (50) i vann slik at varmfriksjon på resten av prosjektilet (50) imngås. Prosjektilet (50) har videre en anordning (90) for stabilisering i tverretningen, hvilken anordning kommer i berøring med siden av kavitasjonshulrommet hvis prosjektilet (50) svinger inn i en vegg i kavitasjonshulrommet (30), når prosjektilet passerer gjennom varm, hvorved det fremkormner en gjenopprettende kraft som hindrer prosjektilet (50) i å tumle.A projectile (50) is driven from a point in air through an air / water interface and towards an underwater object (24). The projectile (50) has a front end (52) which creates a cavitation cavity (30) adjacent to the projectile (50) in water so as to avoid hot friction on the remainder of the projectile (50). The projectile (50) further has a transverse stabilization device (90) which contacts the side of the cavitation cavity if the projectile (50) swings into a wall of the cavitation cavity (30) as the projectile passes through heat, thereby producing a restoring force which prevents the projectile (50) from tumbling.
