Description

ammunition Philippe and 3X649 The present invention has for its the packaging of of the type comprising a projectile and a detachable in particular artillery Ammunition has to be protected against corrosion due to exterior effects of the surrounding and against damage resulting from such as dislocation In the ammunition of the kind a shell of or combustible material is mounted or stuck on the The weak point of this kind of ammunition is the zone of contact between the shell and the In the course of exterior stresses are produced which tend to loosen the assembly and may destroy the rigidity of the ridge as well as the alignment of the projectile and the Known packaging means comprise a casing and cardboard supporting means enclos the In the course of a mechanical effect resulting from the supporting means which support the cartridge only at do not ensure a sufficient shock absorption and the necessary positioning required for a good hold of the both when the fall is on a side wall or on an end wall of the The invention illustrated by way of examples only in the accompanying in 1 is a perspective view of a protecting according to the invention for the ogival tip of a piece of 2 is a perspective view of the cover of the 11 and 12 are perspective views of two half shells of a packaging according to the and 7 are exploded perspective views showing 9 and 10 are similar perspective views from the ogival tip 13 is a perspective view of the open and 14 is a perspective view of a partly broken open nd showing an ammunition packaged in accordance with the invention positioned The principle of packaging according to the invention is to support the cartridge all around in such a manner as to distribute the stresses due to fall on large a surface as possible so that the pressure exerted on the supporting moans The cartridge thus has to be in contact with the supporting means along the entire exterior which ensures a continuous the ogival tip of the projectile is often pointed so that pressure on the bottom may lead to a piercing of the supporting which in turn entrains a deterioration of the This is overcome in accordance with the invention by encasing the front part of the projectile in a protecting sleeve designed to distribute an axial pressure over a larger In order to ensure the greatest possible cohesion of the assembly and to avoid any rebounding of the ammunition within the casing the supporting may be adapted for tightening upon closure of the cover of the outer in order to ensure the the ammunition is wrapped in an of insulating More by way of example there now follows a description of the packaging of two tank They A A tiht envelo e of rilsan indicated at 4 in the and In order to increase the efficiency of this function it is possible to evacuate the space between the envelope and the ammunition so that the envelope is in tight with the At its ends the envelope comprises incisions 4a facilitates the tearing off of the A protecting sleeve 5 7 and for the ogival tip made of polyethylene and which is in all cases where the ammunition has a conical or ogival The form of this sleeve is adapted for each type of Its functions are on the one hand to protect the fragile components of the front part of the cover in order to prevent during a shock the striking of these parte on the on the other hand to absorb axial stresses which are at their maximum in case of a shock from the For thi purpose the following is That the protecting sleeve should bear on a resistant portion of the for the ogival tip the shape of its inner space 5b will be designed in such a manner as to be in contact with the ogival tip in such a manner as not to bear on any fragile portion cover ribs 5d may optionally be provided in order to increase the rigidity of the The protecting sleeve has to be capable of deformation during shock without that the tip of the projectile be able to pierce the To this end its outer shape 5a is determined both as regards its length and thickne s as a function of the maximum falling stress to be absorbed in consideration of the following s d where energy from a given dropping height defined for a given e The highest deformation of the sleeve admissible without that the ammunition pierces the P The breaking power of the protecting x The longitudinal dislocation of the ammunition within the The breaking power F must not exceed the limit of the longitudinal resistance of the part is rounded off and comprises ribs designed to orient the Two half shells 3 shown in 11 and and being fcriaed within as a total or partial of the ammunition 6 in 6 and so as to be adapted to match as completely as possible the shape of the In this a proper shock absorption in all directions is which in turn in case of falling or avoids or reduces to negligible proportions any deformation of the ammunition and preserves the characteristics of the latter required for its Por the event of a fall on the bottom the packaging coraprisee a rear end wall with a clearance 3a which ensures pyrotoohnical safety and provides at the same time a satisfactory crushing within the limits of the relation The diameter of the shell is so calculated as to ensure a tightening upon closure of the The material from which the two half ahellsare made should be of closed cellular structure such as assembly and a good thermal An outer packaging indicated at 1 and 2in 13 and which transportation and storage and ensures the oohesion of the casing may be of wood ox of any other suitable such as for insufficientOCRQuality

Claims

1. An enclosure for an ogival shell, said enclosure conprising casing means defining a cavity for said shell, and a ferrule fitted on said shell on the tip thereof and supported within the cavity of said casing means to protect and cushion said tip, said ferrule comprising a deformable outer body portion with opposite ends, said tip of the shell being insertable in one of said ends, a stiffened conical inner body on said outer portion for engaging the tip of the shell when inserted into said one end, the other end of the outer body portion including ribe thereon.

2. An enclosure as claimed in Claim 1 wherein said outer body portion is outwardly flared at said other end.

3. An enclosure as claimed in Claim 2 wherein said ribs on the outer body portion extend radially thereon at said outwardly flared end,

4. · An enclosure as claimed in Claim 1 comprising an outer cover means enclosing said casing means and including a box and lid.

5. An enclosure as claimed in Claim 4 wherein said casing means comprises a pair of half casings engaged together and tightly fitted within said outer cover means, said cavity in said casing means being formed in both half casings to provide a shape corresponding to the shell with the ferrule mounted thereon whereby the shell and ferrule are supported over their entire surface by the half casings.

6. · An enclosure as claimed in Claim 1 wherein said casing means comprises a pair of half casings engaged together to hold the shell and ferrule thereon within the half casings.

7. An enclosure as claimed In Claim 6 wherein said half casings are constituted of an expanded cellular polymer.

8. An enclosure as claimed in Claim 1 wherein said ferrule includes circumferentially spaced radial ribs between said inner and outer body portions.

9. An enclosure as claimed in Claim 1 comprising a flexible, impermeable wrapping material covering said shell and hernie-tically sealing the shell therein.

10. An enclosure as claimed in Claim 6 wherein said half casings are provided with notches for providing a clearance with the shell at the center of the base thereof. For the Applicants PARTNERS IS:CB
