Abstract
Abstract An explosive device is provided in the form of an inflated spherical bag or envelope which is filled with an explosive mixture of fuel and air. In this way, a maximum of explosive effect is attained with a minimum of weight and bulk. The device is useful in warfare where dense foliage is encountered since it can be inflated and laid or dropped upon the top of trees, bushes or the like where its explosive effect will have a wider range than if the explosion took place down inside the foliage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
An explosive device comprising, in combination, an inflatable envelope, a tank of pressurized fuel, an aspirating air inlet to said envelope, a fuel conduit entended from said tank into said air inlet and exiting there, a valve in said conduit, an igniter exposed to the envelope''s interior, means for initiating operation of said igniter, and the aspirating air inlet comprising a collar open both to the envelope and to the atmosphere and substantially surrounding but spaced from said inlet conduit to define a substantially annular space therebetween for the entry of air, whereby fuel flowing from the conduit causes air to be drawn into the envelope along with the fuel and the fuel becomes ignited therein.
Claim 2
Dependent Claim
