Abstract

A projectile comprising a body having a channel, one or more recesses in the channel, a plunger in the channel, and a fluid in the channel is provided. When the projectile impacts a target, the plunger is driven down the channel, exerting a force on the fluid. The fluid, in turn, exerts fluidic pressure within the recesses, promoting rapid yet predictable expansion of the projectile. Another embodiment of the present invention provides a projectile utilizing a non-Newtonian fluid to optimize expansion of the projectile upon impacting a target.

Claims

1-60. -60. (canceled)

61. A projectile comprising:

a. a body;

b. a channel located in the body, wherein the channel contains a non-Newtonian fluid comprising at least a shear thickening fluid;

c. a plurality of recesses located in the channel, wherein the plurality of recesses cause expansion of the body by directing a pressure received from the non- Newtonian fluid; and

d. a plunger located in the channel, wherein the plunger transmits a force to the non- Newtonian fluid upon striking a target, causing the non-Newtonian fluid to exert the pressure on the plurality of recesses located in the channel.

62. The projectile of claim 61, wherein the plurality of recesses includes a first recess comprising at least a horizontal groove.

63. The projectile of claim 62, wherein the first recess comprising at least a horizontal groove further comprises at least two surfaces that join at a first apex to focus the pressure on the body.

64. The projectile of claim 61, wherein the plurality of recesses comprises a first recess comprising a first horizontal groove and a second recess comprising a second horizontal groove.

65. The projectile of claim 64, wherein the first recess comprising a first horizontal groove further comprises at least two surfaces that join at a first apex to focus the pressure on the body.

66. The projectile of claim 65, wherein the second recess comprising a second horizontal groove further comprises at least two surfaces that join at a second apex to focus the pressure on the body.

67. The projectile of claim 61, wherein the plurality of recesses includes a first recess comprising at least a vertical groove.

68. The projectile of claim 67, wherein the first recess comprising at least a vertical groove further comprises at least two surfaces that join at a first apex to focus the pressure on the body.

69. The projectile of claim 61, wherein the plurality of recesses comprises a first recess comprising at least a first vertical groove and a second recess comprising at least a second vertical groove.

70. The projectile of claim 69, wherein the first recess comprising at least a first vertical groove further comprises at least two surfaces that join at a first apex to focus the pressure on the body.

71. The projectile of claim 70, wherein the second recess comprising at least a second vertical groove further comprises at least two surfaces that join at a second apex to focus the pressure on the body.
