It will be readily seen that at this instant, and as the liquid is being ejected through the passage under high pressure into the reduced pressure area in the wake of the projectile, conditions are ideal for causing vaporization of the liquid. The resulting gas or mixture of gas and liquid will follow through the opening at a reduced speed and expand out of the wake within the target.

9 Claims.
This invention relates to a projectile of the kind containing a charge which is rendered e1- iective upon impact of the projectile with, or its penetration of, an object located in its path of flight, and more particularly the invention is concerned with a projectile characterized by a fluid charge which, when rendered effective, is released in the form of a gas, spray or mist.
One object of'the invention is to provide a projectile which is so designed as to insure the conveyance of its charge in the manner intended without premature release thereof as a result of the motive forces availed of to propel the projectile to the point at which such charge is to be rendered effective. A further object is to provide a projectile which is adapted, when its charge is released, to effect rapid and complete vaporization of the .charge and dispersion over a wide area of the vapors, or gases, so produced.
A still further object is to provide a projectile which may be designed with a high degree of accuracy to effect the release of its charge when the impact force approximates the value of the force to which it would be subjected in penetrating a predetermined target which it is intended to destroy or render inoperative.
A still further object is to provide a projectile wherein the charge is confined in such a manner that any danger of its unintentional or accidental release is eliminated while the necessity of special handling and other precautionary measures are avoided.
The invention is illustrated in the accompanying drawing, in which:
Figure 1 is a sectional view of a projectile embodying the features of the invention.
Figure 2 is a similar view of the projectile, the parts being shown in the relative positions which they assume upon impact with a target.
Figure 3 is a longitudinal section taken along line 3-3 of Figure 1.
Figure 4 is a transverse section taken along line tt of Figure 1.
Figure 5 is a perspective view of the closure bar of the projectile.
Figures 6 and 7 are perspective views of the inner and outer body elements, respectively, of the projectile.
Figure 8 is a perspective view of the container for the fluid charge.
Figure 9 is a perspective view, partially in section, of a modified form of projectile.
In Figure 1 of the drawings a preferred form of the projectile is shown at Ill in connection with the forward portion 12 of a cartridge. The cartridge is of conventional type and includes the usual detonating cap, powder, and wedding which are not shown. The body of the projectile I0 is comprised of a pair of telescoping members It and It. The inner or smaller diameter telescoping, member l8 fits snugly within the bore of the outer member I4 and is grooved circumferentially at 20 to form a recess into which the outer member I4 is depressed to form a shearable interlocking means for securing the telescoping members against relative movement with one another during such handling as may be necessary before the projectile is placed in the gun barrel for firing and during the flight of the projectile. The members it and If! that form the body of the projectile terminate at their rear ends in a plane that is at right angles to the axis of the projectile and are engaged in said plane by a reinforcing member 22 which is in the form of a circular disc.
Various kinds of projectiles consisting of telescoping parts have, heretofore, been devised for conveying a charge to a target and for utilizing the forces resulting from the impact of the projectile with the target to actuate said parts and thereby render such charge effective. Some of these projectiles have been designed to detonate and disintegrate upon impact with the target or other object, others have been designed to spread outwardly, or expand, so as to form large jagged holes in the objects which they penetrate, and still others have been designed to carry fluids and gases adapted to bedispersed in the target area. These projectiles frequently fail in their purpose because the forces created within the gun barrel by the propellant are greater than the forces resulting from the impact of the projectile with its target. The charges carried by the projectiles, therefore, are in many instances rendered immediately eflective by the force of the propellant utilized to eject the projectiles from the gun and hence are ineffective as of the time that the projectiles arrive at the target area.
In the present invention the reinforcing plate 22 that abuts the body of the projectile acts as a piston in the gun barrel and pushes the parts of the projectile ahead of it as a unit. The reinforcing plate because of its rigidity and its engagement with the movable parts of the projectile prevents shifting of the projectile parts while the projectile is moving through the gun barrel.
The inner telescoping member ,l8 is bifurcated at the end thereof that abuts the reinforcing plate 22 to form a pair of legs 24. A T'-shaped member 26 which is apertured as at '28 extends between these legs and the ends thereof are accommodated in T-shaped slots 30 which are formed in the outer member at diametrically opposite points. The length of the legs 24 is such that the bifurcation in the inner member l8 cooperates with the outer member to form a chamber 32 in the body of the projectile with the apertured member 26 forming one of the chamber walls. The aperture 28 in member 26 connects the chamber with the outside of the body and at the rear end thereof. This aperture is preferably closed by a frangible or rupturable receptacle 34 which is located within the chamber and which contains a volatile fluid.
For ease in manufacturing the projectile it may be found to be desirable to associate the member 28 with the outer telescoping member l4 by form ing it integrally therewith, as shown at 21 in Figure 9. In such case the integral member 21 forms the rear end of the outer telescoping member I 4 and is apertured at 38 and 40 as shown in Figure 9. The legs 24 extend through the apertures l and abut the reinforcing plate 22. The aperture 38 connects the chamber 32 with the rear surface of the projectile.
The projectile is designed to convey a fluid to its target and to vaporize the fluid into the wake of the projectile upon impact with a target. In operation, when the explosive charge within the cartridge is ignited the propellent gases that are created behind the reinforcing plate cause the plate to be forced through the gun barrel. The reinforcing plate pushes the projectile through the barrel, and because of its rigidity and because the major parts of the projectile bear against the plate there can be no shifting of parts relative to one another. During flight the reinforcing plate falls away from the body of the projectile to leave the rear surface of the body exopsed to the low airpressure area in the wake thereof. When the projectile strikes a target the speed of the inner telescoping'member is suddenly decelerated and the outer telescoping member, because of its momentum, moves forwardly on the inner member shearing the interlocking means and moving the member l4 forwardly thereby creating pressure upon the fluid in the receptacle, which pressure fractures the receptacle at the aperture 28 or 3B, Continued forward movement of the outer member causes the movable wall 26 to crush the receptacle and thereby cause the fluid therein to be ejected under pressure through the aperture and into the wake of the projectile.
The leading edge 42 of the outer telescoping member upon contacting the dimple-like opening formed in the target by the nose 44 of the inner member will be swedged inwardly about the nose of the member 18 as is indicated in dotted lines in Figure 2 and the casing will enlarge and pass through the opening. It will be readily seen that at this instant, and as the liquid is being ejected through the passage under high pressure into the reduced pressure area in the wake of the projectile, conditions are ideal for causing vaporization of the liquid. The resulting gas or mixture of gas and liquid will follow through the opening at a reduced speed and expand out of the wake within the target. The result of this action in effect is to punch a hole in the target and then to inject a gas into the target through the hole. When the target that the projectile strikes is a hollow object such as a tank or the fuselage of an airplane for example, the projectile is actuated upon entering the target and it is again subjected 4 to a fluid-discharging blow while it is inside the target when it strikes the wall thereof through which it will make its exit.
The forward speed of the vaporized fluid in the wake is less than that of the projectile because it is ejected in a direction that is opposite to the direction that the projectile is traveling. The projectile may be designecrso that the impact required to discharge the fluid therefrom varies according to the thickness of the intended target by controlling the shape of the circumferential groove 20 on the inner member IE to thus predetermine the quantity of material that must be sheared by the striking impact of the. projectile.
There are a number of chemical substances which might be conveyed in the projectile. Among them are incendiary fluids and war gases that have been liquifled. Phosgene and mustard are examples of such chemicals.
The projectile may be fired from guns that are in use at the present time without any change in their construction; it is safe to handle and store; and it would prove highly eifective, for example, in anti-tank warfare if used in connection with "mustard." The crew of a modern fighting tank wear light gas pervious clothing because of the heat in the cab of the tank. If a "mustard projectile" were to be flred through the tank, though the projectile did no vital damage to the mechanism the result would be fatal to the lightly clothed crew. The wearing of gas impervious clothing in a modern tank in certain parts of the world as a precautionary measure would work a most extreme hardship upon the crew because of the attendant heat.
It is to be understood that the projectile may likewise be used in airplane machine guns for attacking enemy aircraft in a manner similar to that in anti-tank warfare and that it may be also utilized to introduce an incendiary fluid into the fuel tanks or other parts of the aircraft. While in certain instances an incendiary compound in the closed fuel tanks of an airplane may not prove immediately eifective because of the lack of oxygen in the tank's, it would very likely achieve the desired result during refueling when the fuel tank filler caps are removed and oxygensaturated gasoline is placed in the tanks, The results obtained under such circumstances may damage the enemy to a much greater extent than would the loss of the airplane during combat.
It is to be understood that the form of the projectile shown and described may be readily varied without departing from the scope of the invention.
