Description of the invention (2) The function of the end cover of the U2 'launch box is to seal the launch box to store the sex gas in the box to prevent moisture from entering and preventing foreign objects from invading. There are two types of methods, such as blasting type and .automatic type, such as Patent Bulletin No. 304 226, which is a type of blasting end J :: Detonating explosive can cut off the second lock between the end cover and the launch box. Throw the end cap away from the box opening. again? The purpose of the bolt is to move the mechanical component to achieve the failure of the opening component, which will cause the end cap to fail to open. J So Ren-wu is the advantage that the missile in the box will not open when it exits the box. The advantage is lower reliability, because ρ: "The bomb body causes any damage, but the disadvantage is that the end cover cannot be opened. If the missile goes ^ er When the component fails, the consequences will be very serious. Ι = explode within Π, closing the box ~: cracked fork, when the missile tip hits the end cover 睥, bursts and bursts, the flying I bursts out The disadvantage of the cake cover is that the target is tracked from the outside, and the surface of the bullet r will be scratched. If the missile is marked with a red mark, the damage of 40% of the surface will affect the missile tracking purpose. Insufficient bulge-type end caps. The present and the Affirmation have developed a high-profile glued arch-type sowing private cover made of several pieces of composite material plate and shell parts, and the end cap will win: The internal punching effect of the missile ignition will swell and split into several plates and shells according to the path of the first victory.

422922 V. Description of the invention (3) — When the plate and shell parts are punched away from the mouth of the box with internal punching, the missiles in the box can be ejected smoothly. Because this design uses the internal pressure generated by the missile to explode the end cap to achieve the purpose of opening ', it is more reliable than the explosive and automatic opening end caps. ί On the other hand, because the missile fired the launch box after the end cap swelled and flew away from the box mouth, this design can avoid the loss of the top-break end cap. Therefore, the main purpose of the present invention is to provide an end cover for a bursting missile launch box, in particular an end cover for a bursting missile launch box made of composite material. The inert gas in the storage box prevents the paint from entering and prevents foreign objects. Invades to protect missiles inside the meal. The secondary object of the present invention is to provide the end cap of the 锸 # bomb ignition type blasting missile launch box by using the internal pressure generated by the ignition of the missile to swell the end cover to achieve the purpose of opening.

The main purpose of this month is to provide a kind of bursting missile which is produced by firing several pieces of composite material plate and shell parts with seam strips and glued into the shell. When the stamping acts on the end cap, the end cap will press = Membrane: J The missile inside the box can go smoothly after leaving the box ::, some plate shouts fly with the punching, and other purposes and advantages of this case will be detailed and defined in the scope of patent applications, among which, Progress in the middle of the month-step description

Description of the invention (6) Detailed description of the invention: Please refer to FIG. 1 to FIG. 4 first, a composite according to the present invention An example of the end cover of the missile launch box is described with an embodiment. Basically, it should be a slab-shell structure with a micro-arch, and it is connected to the launch box (80) at its base. The end cap can basically form a base by an outer frame (50),-\ So (60), (70) butt to form the shape of the outer arch, and the seam strip (2〇) = pieces I pieces glued at the seams' It is connected to the launch box by the fixture group (40). In this embodiment, the plate and shell pieces (60), (70) can be triangular or angular. Four pieces are butted along one edge to form an approximately pyramid or: The clever sample group of plate and shell pieces can be further based on a triangle. The upper part (63) and the lower rectangular side ear (64) are respectively provided, so that the side ear forms a skirt approximately at a right angle to the shooting box, while the upper rectangular side ear slightly protrudes from the lower rectangular side ear and opens ;: A stepped shape or a base to fit into the outer frame d 'The outer frame (50) is responsible for forming the base of the end cap, which can be any shape of any cross-section | preferably a symmetrical geometric shape, such as a circle Or, in the present embodiment, the pyramid-shaped base formed by the four plate and shell parts is exactly a regular shape, and then the outer frames can cooperate to form a square to be connected to each other. The plate shell member and the outer frame together form the basic structure of the end cover of the bursting missile launch box of the present invention. At this time, at least one side where the plate shell member is connected to each other can be glued with a seam strip (20). The seam strip mainly reinforces the joints of the plate and shell parts, and also provides an airtight C: \ kanA bursting end cap patent application (3) \ cover.pt (g 10 page 422922 is based on the drawing number (21) line ab At the moment of birth, it is high and separated, and the joint strength part (2 2) is set or the material itself forms a dynamic failure point. It will end to the entire end. 5. The function of invention description (7), including the first one. Proper launch box (80) The seam strips are glued or have different geometries. In this embodiment, the seam strips are close to the failure starting point (2 4). When the missile launches its dynamic damage, it extends away from the launch box. Two joints, a 'depending on the strength of the seam when the missile fires in its seam' makes one of them, at the same time, the pressure on the glued surface of the tip of the first joint end cap is close to the internal pressure of the base to cause the fracture to develop from one end to another (22) As 囷 5 is relatively wide, the pressurized gas can be separated to overcome the lower joints of the first and second joints, so as to be separated first. The smaller 'forms a dynamic bad end point (2 5), such as at the top. And at the same time its cover destroys the clothing and opens The shell parts are glued with seam strips. 'You can borrow a fixture set (40) and the upper and lower enclosure frames (42) (41) of the launch box, which is approximately where the upper enclosure frame (42) protrudes slightly from the lower enclosure to make the end When the outer frame (50) of the cover can fit exactly, the upper and lower walls can be bolted (4 3). It is clear that the end pressure between the outer frame of the end cover and the plate and shell can ensure or control three times the damage pressure of the internal and external pressure. That is, the foreign body does not damage the structure of the launch box, and at the same time it destroys the diameter. Also, the end cap body can be provided with airtightness on one side. After being inserted into the outer frame to form the end cap body, the combination is shown in Figure 6. The clamp set has a ring-shaped element equivalent to the outer frame (50). The frame (41) forms a similar anti-staircase, and under the anti-steps of the upper and lower enclosure frames, this frame is joined to the missile launch box ^ It is worth saying that it can be glued with resin In this way, it can further strengthen the strength. Typically, the external pressure can be easy to damage the launch box, and the internal pressure can be easier. The path can be broken along the design of the seam strip.

As an example, FIG. 7 exemplarily indicates different combinations, in which the same component numbers represent equal or similar components to help understand. Figure 7a indicates that the plate and shell parts (60) and (70) of this case are rectangular plate and shells composed of two continuous triangular plates. 'The plate and shell parts of Figure 7b are arc-shaped, and Figure 7c indicates a similar arc-shaped But the number is different ^ Of course, the number, material, geometric size and shape should not be limited by this case, but only the choice of design. In addition, according to Fig. 7a, the outer frame should be rectangular or square, while Fig. 7b and Fig. 7c need a round outer frame. As for the composition of the outer arch and the outer arch of the plate and shell components, the connection is almost the same ', but the loading surface is different. The function of each component is summarized and the method of gluing the end cover is explained as follows: ^ The outer frame (50) is a rectangular (or matching the shape of the launch box mouth) frame, and its height is equal to that of the lower ear (64) The height is the same.

5. Description of the invention (9) The plate and shell parts A (60) and B (70) are similar, and the structure and function of the plate and shell part A (60) are described below. The plate and shell parts are formed by gluing two upper and lower plate and shell pieces, and each full plate and shell piece is formed by a triangle plate (61 or 62) and a rectangular edge lug (63 or 64). The width of the ear (63) is larger than that of the lower ear (64). The side of the lower shell ear (64) is glued to the inner side of the outer frame (50) and the upper ear (63) is glued to the outer surface of the outer frame (50). Inside, other plate and shell parts are preliminarily formed into an arched structure after being glued to the outer frame (50) in the same manner. Glue the seam (23) of each adjacent plate and shell piece, and paste the composite material seam strip (0) along the upper surface of the seam = both sides of the plate and shell piece (60 and 70) to cover the two plate and shell The seam (23) of the pieces is shown in Figure 5. f Slit ⑵) * The dashed line ab75 bonded to two adjacent plates and shells with an unobtrusive area (or width) indicates the joint (23) between the two plate and shell parts, and mm is glued to the plate and shell part B (70) The area (or width) tb is much larger than the area (or width) of the plate and shell. Changing the area (or width) of the plate and shell A (60) and, the adjustable end of the seam (or width) can also be used to seal and prevent air leakage. Other plates: The pieces are also joined in a door-like manner. The end caps are assembled as shown in Figure 3. The sticking is symmetrical to the end cap centerline. Work end: The way of the (20) port is shown in Figure 6, where the two ends of the launch box 2 = boxes (41) and (plug 42). The function of the pivot is to place the end cover outside the frame (between one Rubber washer (44)

422922 V. Description of the invention (10) In order to increase the sealing effect of the end cap and prevent leakage. In the two enclosure frames, the lower inner side is close to the outer side of the end cover outer frame (50). The high yield of the lower enclosure frame (41) is the same as that of the end cover outer frame (50) and rubber washer (44). The inner side of the upper enclosure ^ (4〇) is next to the upper ear (63) of the end cover shell, and the two enclosure frames are locked on the box mouth lugs (81). The special feature of M lies in the gluing method between the components. The glue design used is I = when broken, it is broken into the unassembled plate and shell according to the original glue path. 5 = Press f away from the launch box mouth. It is explained that when the end cap is subjected to internal punching, the second is = after, and when the standby end cap is subjected to internal punching, the joint (23), the seam line ⑵) of the plate and shell parts (60 and 70) and Both the surface area of the plate and shell (6 ()) surface and the π ϋ I t bu () gluing place are caused by excessive internal forces to move and break.

The view of the degree of hardening of the component and time) is shown in Figure 8. At 20 ° C to 400 ° C, the surface is smoothed at 0.5 at an upper mold covered with an auxiliary material and coated with resin to make it pressurize. The grease stacked on the component in a staggered stacking method with the component manufacturer that is heated can be determined by the nature of the resin in the process of forming the component at the end of the composite fabric layer. However, for general resins, the pressure is between 5 psi hours and 48 hours for processing and resin-coated end caps. The end caps of composite seam strips are clamped. The combined end caps are the same. . After demolding, the hardening parameters (pressure, temperature) used in the hardening molding work (pressure, temperature) of the upper and lower surfaces covered with cotton blankets and demoulding pressure and heating for easy demolding can be obtained. If epoxy resin is used, its forming temperature and pressure and its hardening and molding temperature are maintained at 800 psi for double hardening. The joint between the outer frame and the plate and shell will place the treated component in the Then paste it on the joints of the various plate and shell parts, and finally cover the auxiliary material and the mold under the end cap. Then, use the hardening conditions used in the mold assembly and the above-mentioned end caps for analysis and verification: ^ Application The finite element method analyzes the mechanical behavior and stress distribution of the end cap to explore its failure mode and burst strength. In the finite element analysis mode, components such as the outer frame (50), plate and shell parts (60 and 70), and glued layers (23 and 51) are simulated using three-dimensional solid elements, while seam strips (20) are simulated using two-dimensional plate elements. The above finite element analysis is performed by NASTRAN commercial finite element analysis software. \ kam \ Expansion end cap patent application Please (3) \ c〇ver pt (page 15 422922 V. Description of the invention (12) A failure analysis is based on the maximum stress failure criterion to determine whether the component and the winner layer have failed. The analysis results show that the damage only occurs At the glued layer between the joining member and the structure, these damages will extend until the members are separated from each other. The analysis results also show that the allowable external pressure is about 3 times the allowable internal pressure. First, the small composite end cap is made pressure resistant. Strength analysis, the length, width, and thickness of the outer frame of the end cap is 2 5 (: 111 \ 25 <: 1 [1 \ 0_27 (: 111 'with an intermediate height of 0.28 (: 1 «, the planar area covered by the plate and shell parts is 16. Ocmxll .6cm, the thickness of the plate and shell is 0.27 cm, the width of the seam strip on the fracture surface is 0.2cm, and the materials used are glass fiber cloth and epoxy resin. The internal pressure and external pressure of the static end of the end cap obtained by analysis are respectively 15_ 5psi and psi 'while the dynamic bursting internal and external pressures are 13, 5psi * 55psi, respectively. Therefore, the dynamic and static external pressure of the end cap is much higher than its dynamic and static internal pressure, and the analysis results also show that the end cap The damage occurred along the joints of the members. Next, the above The cover is enlarged five times to a full-size end cap, but the thickness of the plate and shell parts is changed to 1.1 cm. The analysis shows that the static and internal pressure of the end cap is 5ps soil and 23psi, respectively, and its dynamic burst The internal pressure and external pressure are 3.5 psi and "psi. Similarly, the external pressure of bursting is much higher than the internal pressure of bursting. Then the experimental method is used to verify the feasibility of this creation. First, glass fiber cloth and epoxy are used. Resin is used to make the above-mentioned small end cap test body containing four plates and shells as shown in Annex 1. Then, the test body is subjected to a static and dynamic burst test. The schematic diagram of the experimental device for the burst test is shown in Figure 9. The components are two round tubes, clamp set, pressure pump P, needle PN, and membrane, which are different from each other before and after the first test. The end cap is clamped at the exit of the front round tube with a clamp. Dynamic burst test, the film can be clamped between two round tubes first so that

422922 V. Description of the invention (13) The rear tube becomes -f membrane is placed in the air due to the bulge, and it will be instantaneous. To perform static bursting, the penetration of air can cause the end cap to burst. The test of the dynamic (static) state of the end cap when the bomb is pressed in the launch box can obtain the comparison error between the static and dynamic bursting of the end cap. After the bursting of the percent failure mode to the cap, the sticking inspection is still performed. Due to safety considerations, under this pressure, it is bad. Therefore, the applicant also assembled and manufactured the burst analysis results obtained from the above-mentioned full-scale experiment to compare the error pressure container. When the value is thin, the puncture needle PN in front of it is pierced. At this time, the pressure in the rear round tube is tested on the end cap at the exit of the front round tube, and the film can be removed. At this time, the two round tubes directly act on each other. On the other hand, slowly increase the pressure in the tube and hang the fake bullet M in the front round tube to the right to simulate the effect of flying force. Burst pressure can be obtained by performing the above-mentioned dynamic (static) test. If the end cap is turned upside down, repeat the dynamic (static) state of the above cap to swell the external pressure. The internal pressures at the ends obtained by the experiments were within 17 psi and 15j &si; si 'and within ten of the theoretical analysis society. It has been observed from experiments that the end cover will fly four pieces of plate and shell and fly away from the mouth of the box, and the seam strip (20) is at the end, of which two pieces of plate and shell B (70). As for the external pressure test, the dynamic and static external pressure was only tested to 30 p s i. Even if the pressure resistance of the end cap is still good, the bursting external pressure without any broken cap is indeed much larger than the bursting internal pressure. Another large-scale static burst test device is shown in Annex 3, and the glass fiber reinforced composite end cap is used to perform a static burst test. The pressure and the external pressure are respectively 4.5 p s i and 20 p s i and the theoretical score is within 15%. The external knife analysis and experimental results have proved that the present invention is indeed feasible, that is, the external pressure of the micro-arch is several times greater than the internal pressure, so the end cap can have enough strong HUM missiles to be protected from foreign objects; adjust the seam strip (2 ( )) And plate shell 42 2922

V. Description of the invention (14) The glued area (or width) of (14) pieces (60 and 70) can change the inside of the end cap so that the end cap has sufficient strength to withstand the pressure of the inert gas in the box. When stamping is applied to the end cap, the end cap will be split into a number of plate and shell parts according to a preset damage mode and fly away from the box mouth with punching. The case stated on the table below is that this case should comply with the provisions of the Patent Law i.
