Abstract
The launcher closure with outer cover is adapted to fit on a canister that contains a missile or the like thereby sealing the inside of the canister from the external environment and allowing the missile to be tested. The closure is designed to move only in the event of a fast rise in pressure caused by launch, but to remain in place in the occurrence of a slow pressure leak. The closure is in a predetermined shape such as a cylinder or the like with one end of the tube containing an O-ring to seal the canister and closure, and the other end of the closure with a surface. The closure, when attached to the canister, seals the inside of the canister from the external environment.
Description
- [0001] This invention was made with Government support under Contract No. DASG60-00-C-0072 awarded by the Department of Defense. The Government has certain rights in this invention.
- The invention relates to a missile canister and, in particular, to a missile canister having a pressure sensitive cover.
- Weapons such as missiles whether on land or on naval vessels are currently stored in canisters that protect the weapon from the external environment during transportation. The canister that houses the missile is, typically, an elongated tube having at least one opening wherein a cap is placed on the opening effectively sealing the canister.
- When the missile, or the like, is launched, several methods have been proposed allowing the missile to egress from the canister. One system has a cap composed of a lightweight material attached to the canister. When the missile is launched and egresses from the canister, the missile strikes the cap thus causing the cap to fracture. However, this cap which permits moisture and other external elements inside the canister may cause the missile to malfunction. Additionally, when the missile strikes the cap, the cap projects debris in a random manner with ensuing damage to the missile.
- Another method has a pyrotechnic device within, or near, the cap, wherein the device is operatively coupled to the missile. As the missile is launched, the pyrotechnic device is activated causing the cap to decouple from the canister allowing the missile to egress from the canister unencumbered. Unlike the first method wherein fragments of the cap are projected in a random manner, the entire cap is released from the canister. By fitting a cap with a pyrotechnic device, the missile cannot be periodically tested since the pyrotechnic device activates upon the firing of the missile.
- The problem is that no canister and cap allows the missile, or the like, to be tested or to be protected from the external environment.
- The present invention features a cap covering an opening of an elongated canister wherein the canister has at least one open end. The cap has an inner cover with two ends. A first end of the inner cover is enclosed and an outer cover has two ends wherein a first end of the outer cover is enclosed. Both the inner cover and outer cover are operatively coupled to each other. Between the first and second end of the outer cover is a surface having at least one hole wherein at least one protrusion projects from the hole.
- In another embodiment, the present invention features a cap wherein the cap has a pressure sensitive system and at least one protrusion protruding in a radial direction to the cap. The pressure sensitive system is operatively coupled to at least one protrusion.
- The above and other advantages and features of the present invention will be better understood from the following detailed description of the preferred embodiments of the invention, which is provided in connection with the accompanying drawings. The various features of the drawings may not be to scale. Included in the drawing are the following figures:
- FIG. 1 is a perspective view of the launcher closure.
- FIG. 2 is a perspective view of the outer cover of the launcher closure.
- FIG. 3 is a perspective view of the bearing seal that is within the outer cover of the launcher closure.
- FIGS. 4a and 4 b are a view of the launcher closure attached to a canister.
- FIG. 1 details the launcher closure10 having inner cover 11 and
outer cover 21. While FIG. 1 shows that inner cover 11 andouter cover 21 are substantially circular in shape, other shapes can be utilized without departing from the spirit of the present invention. For example, inner cover 11 andouter cover 21 can be in the shape of rectangles known within the art or inner cover 11 andouter cover 21 can be any polygon shape. - Inner cover11, as shown in FIG. 1, has two ends wherein the first end is substantially enclosed and the second end is, preferably, not enclosed (not shown in FIG. 1). The first end of inner cover 11 has a plurality of holes and the surface that intersects between the two ends is tapered (See FIGS. 4a and 4 b).
-
Outer cover 21 features a substantially continuous surface having two ends. The first end of theouter cover 21 is substantially enclosed by a second surface and the second end is not enclosed. Preferably, formed, by means well known in the art, to the second end of theouter cover 21 is at least onegroove 23 that is substantially the same shape as the opening of a canister (not shown in FIG. 1). Whilegroove 23 is described as being attached toouter cover 21, it would not depart from the spirit of the present invention to havegroove 23 andouter cover 21 to be of unitary construction.Groove 23 is substantially continuous and, preferably, an O-ring or the like is placed within thereby effectively sealing the inside of the canister when launcher closure 10 is attached. Additionally, the O-ring protects the contents of the canister from electro magnetic interference. - The
outer cover 21 also features a plurality ofprotrusions 22 substantially perpendicular to the enclosed second surface. Theprotrusions 22 substantially align with the holes in the first surface of the inner cover 11 allowing both the inner cover 11 and theouter cover 21 to be attached by a conventional means. For example, a hole can be cut at a predetermined place within theprotrusions 22 and a cotter pin, or the like, can be used to fasten the inner cover 11 to theouter cover 21. - Projecting in the radial direction with respect to
outer cover 21 is a plurality ofball bearings 14, or the like. Preferably, the open end of the canister (not shown in FIG. 1) features a continuous groove within the inside of the canister or the groove can be placed on the outside of the canister. In other embodiments, holes, divots, or the like can be placed at predetermined points around the inside of the canister. The holes or continuous grove allow theball bearings 14, or the like, to create a frictional attachment permitting the launcher closure 10 to be releasably attached to the open end of an elongated canister. While the launcher closure 10 describes the use ofball bearings 14 that releasably attach it to the open end of an elongated canister, other embodiments can exist. For example, roller bearings, or the like, can project in the radial direction to theouter cover 21 allowing the closure 10 to releasably attach to the open end of an elongated canister. - While not shown in FIG. 1, it is to be understood inner cover11 fits within
outer cover 21 and these elements are operatively coupled together, which is described below. - FIG. 2 is a detailed view of
outer cover 21 havingprotrusions 22,groove 23 and a plurality ofholes 24, as substantially described above.Outer cover 21 is a substantially continuous surface, as described above, which fits inside the opening of a canister (not shown).Holes 24 are cut within the surface of outer cover 11 allowing theball bearings 14, or the like, to project in a radial direction. While not detailed in FIG. 2,holes 24 may be cut at an angle allowing theball bearings 14, or the like, to retract easily. - FIG. 3 is a detailed view of
bearing ring 30. Whilebearing ring 30 is shown as being substantially circular in shape, it is to be understood that bearingring 30 can be any shape known within the art and additionally,bearing ring 30 can be substantially the same shape asouter cover 21 since bearingring 30 fits within inner cover 11, thereby integrating the feature ofbearing ring 30 within inner cover 11. Bearingring 30 is a substantially continuous surface wherein a plurality ofspring holes 31 is cut into its surface. It should be appreciated, that spring holes 31 can be cut entirely through bearingring 30 or that spring holes 31 can be cut partially through the bearingring 30. Additionally, a plurality of protrusion holes 32 is cut through the surface of thebearing ring 30.Protrusion 22 is aligned and placed throughprotrusion hole 32 allowing bearingring 30 to be connected toouter cover 21. The overall width of bearingring 30, shown in FIG. 3 as Wb, is smaller than the width ofouter cover 21. Therefore, when the launcher closure 10 is attached to the open end of a canister, there will be a gap within the closure 10, which is described below. - While bearing
ring 30 is described as a separate element that attaches toouter cover 21 by theprotrusion 22, it would not depart from the spirit of the present invention to integrate the features of bearingring 30 within inner cover 11. - FIG. 4a details the launcher closure 10 attached to the open end of
canister 41. While launcher closure 10 is shown as being attached to the inside surface ofcanister 41, the launcher closure 10 may be attached to the outside of thecanister 41.Canister 41 is a conventional canister notoriously well known within the art. - The launcher closure10 features inner cover 11,
ball bearing 14,outer cover 21,protrusion 22,groove 23, bearingring 30,spring cavity 31,canister 41,canister groove 42 andspring 43. As shown in FIG. 4a and discussed above, it is to be understood that bearingring 30 is placed within inner cover 11 and inner cover 11 and bearingring 30 are aligned enabling theprotrusion 22 to slide throughprotrusion hole 32 and the hole within inner cover 11 allowing the system to be secured together. While bearingring 30 and inner cover 11 are described as being two distinct elements, it would not depart from the scope of the present invention to integrate bearingring 30 within inner cover 11, that is, there may be only one ring and bearings sit directly on it. - As shown in FIG. 4a, it is to be understood that little pressure is being exerted against inner cover 11.
Ball bearing 14 is withincanister groove 42 since the tapered edge of inner cover 11 is substantiallypressing ball bearing 14 intocanister groove 42. The edge of inner cover 11 prevents ball bearing 14 from moving thereby creating a frictional connection between the launcher closure 10 andcanister 41.Groove 23 contains an O-ring, or the like, effectively sealing the inside of the container from the external environment. -
Spring 43 is contained withinspring cavity 31 and is placed against the bottom ofouter cover 21 and either bearingseal 30. Since there is little pressure being exerted upon inner cover 11,spring 43 is not substantially compressed and agap 44 is formed. Typically, a missile (not shown) or the like held incanister 41 leaks a toxic missile propellant. During these leaks, the pressure within the canister slowly rises. However,ball bearings 14 will not disengage from thecanister groove 42 allowing launcher closure 10 to be attached tocanister 41. While the launcher closure 10 is described as utilizing a spring, it would not depart from the spirit of the present invention to use other pressure sensing devices. - FIG. 4b details the launcher closure 10 has a pressure, P, exerted against inner cover 11. The launcher closure 10 is designed to release from the opening of the
canister 41 when the missile (not shown) is fired and a pressure pulse is exerted against the inner cover 11. This pressure causesspring 43 to compress againstouter cover 21 and bearingseal 30. Inner cover 11 moves in an upwardly direction thereby causinggap 44 shown in FIG. 4a to decrease untilinner cover 21 is substantially touchingouter cover 21. When there is little, or no,gap 44 between inner cover 11 andouter cover 21, the tapered edge of inner cover 11 is no longer pressing against ball bearing 14 causingball bearing 14 to retract from its position. Onceball bearing 14 retracts, launcher closure 10 is removed from the opening ofcanister 41 by the pressure exerted on it. - Although illustrated and described herein with reference to certain specific embodiments, the present invention is nevertheless not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims without departing from the spirit of the invention.
