Non-newtonian projectile
First Claim
1. A bullet that uses a non-Newtonian fluid to promote penetration of a target, the bullet comprising:
- a. a body including a channel, wherein the channel contains the non-Newtonian fluid; and
b. a plunger that is harder than the body and located in the channel, wherein the plunger transmits a force to the non-Newtonian fluid while in contact with the target, causing the non-Newtonian fluid to exert a pressure in the channel, and wherein the viscosity of the non-Newtonian fluid increases with at least one of a shear rate or a shear time while the plunger is in contact with the target, thereby promoting penetration of the target.

Abstract
A projectile is provided comprising a body with a channel that contains a non-Newtonian fluid. In various embodiments a plunger is located in the channel, wherein the plunger transmits a force to the non-Newtonian fluid upon interacting with a target, causing the non-Newtonian fluid to exert a pressure in the channel, and wherein the viscosity of the non-Newtonian fluid changes upon interacting with the target. By way of non-limiting example, the non-Newtonian fluid of embodiments of the present invention can comprise a shear-thickening fluid that increases its viscosity with at least the rate of shear upon interacting with the target.
