Abstract

The invention is a projectile which will not ricochet upon striking a solid object. The projectile has a hull containing a payload cavity with a liquid payload, rotors within the payload cavity, a threaded shaft extending the length of the hull, and propeller fins at the back end of the shaft which make fewer turns than the hull while the projectile is in flight.

Claims

1. A projectile which will self-destruct at a predetermined range and which will not ricochet upon striking a solid object, said projectile comprising:

a hull having a slotted nose cone;

payload cavities formed within said hull, said payload cavities being filled with a liquid payload;

a plurality of rotors disposed within said payload cavities;

a retaining bolt extending at least part of the length of said hull through said payload cavities, said bolt extending through openings at the anterior and posterior ends of said hull;

a retaining nut disposed within said nose cone, said nut holding said shaft in position at the anterior end of said bolt;

two or more fins formed around a hub at the posterior end of said retaining bolt, said fins forming angles with the horizontal axis of said projectile such that said fins rotate more slowly than said hull, thus allowing said retaining bolt to unscrew from said retaining nut while said projectile is in flight.
