Abstract
An explosive device includes an explosive material and a liner. The explosive material includes a void, and the liner is adjacent to a surface of the explosive material in the void. The void has a center axis with a base at a first end of the center axis, a terminal end at a second end of the center axis opposite the first end, and a sidewall therebetween wherein the sidewall has an inflection portion with an angle between 30°and 60°with the center axis.

Claims20
An explosive device comprising:
- an explosive material having a void, wherein the void has a center axis with a base at a first end of the center axis, a terminal end at a second end of the center axis opposite the first end, and a sidewall therebetween wherein the sidewall has an inflection portion with an angle between 30° and 60° with the center axis;
- and
- a liner adjacent to a surface of the explosive material in the void.
The explosive device of any preceding claim, wherein the void has a convex portion of the sidewall proximate the terminal end of the void.
The explosive device of any preceding claim, wherein the void has a linear portion of the sidewall between the base and the terminal end.
The explosive device of any preceding claim, wherein the liner includes silicate glass.
The explosive device of any preceding claim, wherein the explosive material includes a liquid explosive.
The explosive device of any preceding claim, wherein the explosive material has a relative effectiveness (RE) factor greater than or equal to 1.0.
The explosive device of any preceding claim, wherein the sidewall has a first linear portion with a first angle relative to the center axis and a second linear portion with a second angle different from the first angle.
The explosive device of any preceding claim, wherein a focal point of the explosive material is less than 2 centimeters (cm) past the terminal end of the explosive material.
The explosive device of any preceding claim, wherein a focal length of the explosive material is no more than 100% of a void length of the void of the explosive material.
The explosive device of any preceding claim, wherein a spall angle of a liner material of the liner after detonation is between 15° and 75° relative to the center axis.
An explosive device comprising:
- a housing;
- an explosive material positioned radially within the housing and the explosive material having a void, wherein the void has a center axis with a base at a first end of the center axis, a terminal end at a second end of the center axis opposite the first end, and a sidewall therebetween wherein the sidewall has an inflection portion with an angle between 30° and 60° with the center axis;
- and
- a liner adjacent to a surface of the explosive material in the void.
An explosive device comprising:
- a shaped charge, the shaped charge including:
- a housing,
- an explosive material positioned radially within the housing and the explosive material having a void, wherein the void has a center axis with a base at a first end of the center axis, a terminal end at a second end of the center axis opposite the first end, and a sidewall therebetween wherein the sidewall has an inflection portion with an angle between 30° and 60° with the center axis, and
- a liner adjacent to a surface of the explosive material in the void;
- and
- an unmanned aerial vehicle (UAV) configured to carry the shaped charge with the terminal end at or below a skid of the UAV.
