Patent ID: 7966936

Claim:
A telescoping cavitator system for a high speed underwater projectile, the projectile having a forward end, and aft end and a tapered body increasing in diameter from the forward tip to the aft end, the cavitator system comprising: a first cavitator shaped to induce supercavitation, disposed at said forward tip of said projectile, said first cavitator having a cylindrical body of preselected length and a diameter d; a second cavitator, disposed aft of said first cavitator, said second cavitator having an outside diameter greater than that of said first cavitator and also having a cylindrical cavity therein with an inside diameter D adapted to slideably receive said outside diameter d of said first cavitator therewithin, for providing in cooperation a moveable piston assembly; and a fluid medium, filling said cylindrical cavity volume behind said first cavitator piston, to restrict rearward movement of said piston in a controlled manner, said piston moving aft once said projectile has been fired.
