DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration, and is not intended to limit the present invention.

[0032] The present invention provides a gun pod fairing with the function of assisting in fixing a gun, which is used for being installed on a pod body of the gun pod. On the one hand, the fairing is performed through a streamlined shape structure to reduce air resistance. On the other hand, the gun pod has the function of adjusting the level and pitch of the gun. After the position of the gun is adjusted, the present invention can assist in supporting and fixing the gun, enhance the support and fixation of the gun in the pod, ensure the shooting accuracy of the gun, and realize the rapid disassembly and assembly of the gun and ammunition.

[0033] First, the overall reference Figure 1 As an exemplary embodiment of the present invention, the cannon pod fairing with the function of assisting in fixing the cannon comprises a cover 1 and a cannon auxiliary fixing assembly 2. The cover 1 is precisely aerodynamically designed and adopts a streamlined shape structure to reduce air resistance. A support structure is designed inside the cover to improve the rigidity of the fairing. The cannon auxiliary fixing assembly 2 is connected to the axial end face of the cover 1 and is used to adjust and assist in fixing the cannon.

[0034] Combination Figure 2 and Figure 3 The cover 1 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are used to be installed on the pod body respectively. Specifically, the upper shell 11 can be connected to the pod body by a first fastener 13, and the lower shell 12 can be connected to the pod body by a second fastener 14. In particular, a floating convex spiral lock with a self-locking function can be used as a fastener to reliably fix the upper shell 11 and the lower shell 12 to the pod body, and can be quickly removed when needed.

[0035] In some embodiments, a positioning column 121 is provided on the lower shell 12 to guide the installation and positioning of the lower shell 12, so as to facilitate the installation of the fairing. In addition, a plurality of exhaust holes 122 may be provided on the lower shell 12, and the exhaust holes are arranged in multiple rows and columns at equal intervals. These array-type exhaust holes can timely discharge the high-pressure gunpowder gas generated by the aircraft gun shooting, prevent flash explosion, and improve the safety of the aircraft gun.

[0036] like Figure 4As shown, the aircraft gun auxiliary fixing assembly 2 includes a bow 21, a support shaft 22 and two positioning pins 23. The bow 21 can connect the upper shell 11 and the lower shell 12 at both ends, and is used to install the support shaft 22 in the middle.

[0037] Figure 5 The bow 21 is shown, and the two ends of the bow 21 are connected to the upper shell 11 and the lower shell 12 respectively through the positioning pin 23, and the bow 21 is installed to bend toward the cover 1. The axis of the positioning pin 23 is horizontally located in a plane perpendicular to the axis of the cover 1, and the bow 21 can move along the axis of the positioning pin 23 to adapt to the horizontal adjustment of the aircraft gun. Preferably, one end of the positioning pin 23 is provided with a radially outwardly protruding limiting flange, and the other end is limited by a second cotter pin 29 to prevent the positioning pin 23 from being separated from the bow 21.

[0038] The axis of the support shaft 22 is parallel to the axis of the cover 1. One end of the support shaft 22 is used to cooperate with the aircraft gun in the cover 1, specifically inserted into the aircraft gun auxiliary fixing hole of the aircraft gun, and the other end is connected to the bow 21. The support shaft 22 can move vertically relative to the bow 21 in a plane perpendicular to the axis of the cover 1 to adapt to the pitch adjustment of the aircraft gun. After the position of the aircraft gun is adjusted, the support shaft can be inserted into the aircraft gun auxiliary fixing hole. By adjusting the position of the support shaft vertically and the position of the bow horizontally, a stable aircraft gun support mechanism can be formed, thereby enhancing the fixity of the aircraft gun, thereby reducing the shaking and deviation of the aircraft gun during shooting, and thus ensuring the shooting accuracy of the aircraft gun.

[0039] In order to facilitate the adjustable connection between the bow 21 and the support shaft 22, in a specific embodiment of the present invention, the aircraft gun auxiliary fixing assembly 2 also includes an adjustment block 24 and a locking nut 25. The support shaft 22 passes through the vertical long hole 211 on the bow 21 and can move along the long hole 211. The adjustment block 24 and the locking nut 25 are respectively sleeved on the support shaft 22 on both sides of the bow 21 to lock the support shaft 22. The adjustment block 24 can be a rectangular parallelepiped structure, with a middle through hole sleeved on the support shaft 22. The two side surfaces of the adjustment block are respectively in contact with the shoulders of the bow 21 and the support shaft 22, and the shoulders can be processed with a tightening plane that is convenient for a wrench to clamp and screw.

[0040] In order to achieve the locking of the support shaft 22 on the bow member 21, a serration portion 212 is arranged on the side of the bow member 21 facing the cover shell 1, and a serration matching the serration on the serration portion 212 is arranged on the surface of the adjustment block 24 facing the bow member 21 to achieve the fixation of the support shaft 22. Specifically, after the vertical position of the support shaft 22 is adjusted, the adjustment block 24 can be first fitted with the serration portion 212 on the bow member 21, and then the locking nut 25 can be tightened to complete the locking of the support shaft 22.

[0041] In addition, in order to more reliably lock the support shaft 22 on the bow member 21, the aircraft gun auxiliary fixing assembly 2 may also include a first cotter pin 26, which is used to pass through the locking nut 25 and the support shaft 22 after the locking nut 25 is tightened, so as to prevent the locking nut 25 from loosening and failing to lock the support shaft 22.

[0042] In addition, to facilitate the connection between the bow member 21 and the cover 1, the aircraft gun auxiliary fixing assembly 2 may also include two mounting seats, namely a first mounting seat 27 and a second mounting seat 28, which are respectively fixed to the upper shell 11 and the lower shell 12. The first mounting seat 27 is provided with two pin holes 271, and the second mounting seat 28 is provided with two pin holes 281. One of the two locating pins 23 passes through the two pin holes 271 and the bow member 21, and the other passes through the two pin holes 281 and the bow member 21, thereby connecting the bow member 21 to the cover 1.

[0043] Next, the working process of the aircraft gun pod fairing with the function of assisting in fixing the aircraft gun provided by the present invention is described.

[0044] First, the installation process of the fairing is described. After the cannon is installed in the pod and locked, the fairing is installed:

[0045] Step 1, fix the upper shell 11 of the cover shell 1 to the cabin body with a first fastener 13 such as a movable convex spiral lock, and tighten the movable convex spiral lock to make it have a self-locking function;

[0046] Step 2, install the positioning column 121 on the lower shell 12 of the cover shell 1 into the corresponding hole of the cabin body, and tighten the second fastener 14 such as a movable convex head spiral lock to make it have a self-locking function;

[0047] Step 3, inserting the support shaft 22 of the aircraft gun auxiliary fixing assembly 2 into the aircraft gun auxiliary fixing hole;

[0048] Step 4, adjusting the adjustment block 24 along the long hole 211 of the bow member 21, and adjusting the bow member 21 axially along the positioning pin 23, so that the support shaft 22 has no interference in the auxiliary fixing hole of the aircraft gun;

[0049] Step 5, tighten the lock nut 25 and install the first cotter pin 26 and the second cotter pin 29. So far, the installation of the fairing is complete, and the aircraft gun will rush forward and recoil along the support shaft 22 when shooting, thereby reducing the shaking and deviation of the aircraft gun when shooting.

[0050] Then describe the disassembly process of the fairing:

[0051] Step 1, remove the second cotter pin 29, pull out the positioning pin 23, and remove the aircraft gun auxiliary fixing assembly 2;

[0052] Step 2, unscrew the second fastener 14 on the lower shell 12 of the fairing housing 1, and remove the lower shell 12 downward. For normal use and maintenance, removing the lower shell 12 is sufficient.

[0053] As described above, by using the present invention, after adjusting the horizontal and elevation positions of the aircraft gun, the aircraft gun pod inserts the support shaft into the auxiliary fixing hole of the aircraft gun, and can form a stable aircraft gun support mechanism by vertically adjusting the position of the support shaft and horizontally adjusting the position of the bow-shaped member, thereby enhancing the fixity of the aircraft gun, reducing the shaking and deviation of the aircraft gun during shooting, and ensuring the accuracy of the aircraft gun shooting. In addition, the fairing in the present invention adopts a split design, and the cover shell is divided into an upper shell and a lower shell. When loading and unloading the aircraft gun and ammunition, only the lower shell needs to be removed, and there is no need to remove the cover shell as a whole. The disassembly and assembly of the aircraft gun and ammunition is convenient and fast, which is convenient for rapid replacement and maintenance in emergency situations, and at the same time avoids the operator from having to complete the disassembly and assembly of the fairing in front of the muzzle, which will not cause personnel safety risks.

[0054] Finally, it should be noted that the features mentioned and / or shown in the above description of the exemplary embodiments of the present invention may be combined in the same or similar manner into one or more other embodiments, combined with the features in other embodiments or substituted for the corresponding features in other implementations. The technical solutions obtained by these combinations or substitutions shall also be deemed to be included in the protection scope of the present invention.
