5 Claims, 3 Drawing Figures SIMULTANEOUS AJGALLY & RADIALLY IGNITED CASELESS TELESCOPIC TUBE AMMUNITION ROUND The invention described herein may be manufactured, used, and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon.
This invention relates to ammunition rounds and more particularly, concerns telescoped caseless cartridges which embody simultaneous radial and axial ignition.
The principal object of this invention is to provide a caseless cartridge occupying a minimum volume while yet possessing superior ballistic properties.
Other objects and advantages of the invention will become apparent from the following description and accompanying drawings wherein:
FIG. 1 illustrates a sectional view of a round embodying the principles of our invention; and
FIGS. 2 and 3 illustrate a top and side view respectively of propellant plug 30 shown in FIG. 1. Referring now to the drawings, our cartridge has an outer propellant cylinder which is suitably molded and comprises a single base extruded grain propellant, 100 percent nitrocellulose modified with minor amounts of a stabilizer, such as diphenylamine, for example; a deterrent, such as dibutylphthalate, for example; and a flash suppressor, such as potassium sulfate, for example, the actual composition of outer propellant cylinder 10 forming no part of this invention.
The entire length of cylinder 10 is lined with a propellant support or guide tube 12 which comprises a double base propellant, the nitroglycerin thereof falling within the range of about 38 42 percent. Again, small amounts of selected modifiers will be present, such, for example, as diphenylamine, dibutylphthalate, and the like. Support tube 12 is bonded to outer propellant cylinder 10 with a nitrocellulose adhesive, suitably dissolved in a mixture of ethanol-acetone, of roughly 50-50 proportions. Other suitable energetic lacquers may be used advantageously.
Located below projectile 14 is our ignition assembly, which includes a lower propellant cylinder 20 comprising identically or substantially the composition of outer propellant cylinder 10, and is open at both ends, its upper end contacting the lower portions of projectile 14, and its lower portion being coextensive with outer propellant cylinder 10 and support tube 12. Disposed within lower propellant cylinder 20 is inner propellant cylinder 22, made of the same propellant composition as lower propellant cylinder 20. Its bottom end only is open however for receiving lead styphnate type explosive pellets 24 and plug 26, the latter retaining pellets 24 in position thereabove and also providing rapid igni tion from primer 28 and booster 30, due to the nature of its pure nitrocellulose composition.
The primer and booster are essentially of the same composition as that of the outer propellant cylinder 10 but will possess a smaller web and therefore be faster burning grains. The explosive pellet comprising the primer and booster will preferably be of the lead styphnate type. Both primer and booster are enclosed by the lower propellant cylinder and will be placed immediately below inner propellant cylinder 22.'The cylinders 20 and 22 are bonded with a nitrocellulose adhesive,
similar to'that used in bonding outer propellant cylinder 10 to guide tube 12.
Surrounding lower propellant cylinder 20 at its lower portions is a propellant plug 31, which is bonded to both lower propellant cylinder 20 and guide tube 12 with the nitrocellulose adhesive aforedescribed, the plug permitting radial ignition substantially simultaneously with axial ignition through pellets 24. Propellant plug 31 is shown in detail in FIGS. 2 and 3 and comprises a composition identical with outer propellant cylinder 10 and has a plurality of passageways 32 communicating from its periphery to its central portions where it is bonded to cylinder 20. Within each passageway is disposed a nitrocellulose fiber plug 34 for providing rapid ignition from cylinder 20 to explosive pellets 36 disposed outwardly of plugs 34 in passageways 32.
A mica seal or disc 40 is attached or bonded to the base of the cartridge as shown to provide thermal protection to the bolt and firing pin (not shown) as well as erosive protection thereto.
Above plug 31 is free volume 42 which performs its usual function in our ignition system. When the firing pin impacts primer 28 after penetrating mica seal 40, the primer and booster are sequentially ignited which sets ofi' an axial ignition train through plugs 34 and pellets 36. The radial ignition occurs simultaneously along each of the 4 passageways 32 located in propellant plug 31. Gas thus formed from ignition of plugs and pellets and the lower and inner propellant cylinders together with guide tube and outer propellantcylinder push the projectile forward. The ignition of the cylinder 10 and tube 12 will coincide with the ignition of cylinders 20 and 22 to effect optimum velocity of the projectile.
We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
We claim:
1. A telescoped caseless ammunition cartridge comprising an outer propellant cylinder,
a projectile completely telescoped within said cylinder,
