[0006] According to one embodiment of the present invention, it further comprises a torsion spring, which is sleeved on the rotating shaft; one arm of the torsion spring is limited by the pipe opening, and the other arm of the torsion spring is limited by the opening cover.

[0007] According to an embodiment of the present invention, two torsion springs are included, and the two torsion springs are symmetrically installed on both sides of the rotating shaft.

[0008] According to one embodiment of the present invention, a limiting groove perpendicular to the axial direction of the rotating shaft is provided at the first end of the mouth cover, and one arm of the torsion spring is placed in the limiting groove to limit the one arm of the torsion spring; a support is correspondingly provided at the first end of the outer ring of the pipe mouth to limit the other arm of the torsion spring.

[0009] According to an embodiment of the present invention, the limiting groove is formed by two straight plates arranged perpendicular to the axial direction of the rotating shaft; and the support is a straight plate parallel to the axial direction of the pipe mouth.

[0031] Figure 1 is a three-dimensional diagram of a launch vehicle fairing according to an embodiment of the present invention; Figure 2 It is a schematic diagram of the closed and opened states of the cover of the air conditioning interface of the fairing according to one embodiment of the present invention; Figure 3 It is a schematic diagram of a closed state of a cover of a fairing air conditioning interface according to an embodiment of the present invention; Figure 4 yes Figure 3 CC direction section view of the right view; Figure 5 yes Figure 4 A magnified view of middle; Figure 6 yes Figure 4 Enlarged view of B.

[0032] like Figures 1 to 6The present invention provides a fairing air conditioning interface, comprising: a port cover 1, a pipe port 5, a rotating shaft 7, a locking pin 2 and a spring 3. The pipe port 1 comprises a pipe port inner ring 14 and a pipe port outer ring 15, wherein the pipe port inner ring 14 is used to be fixedly connected to the fairing 8, and the pipe port outer ring 15 is used to be connected to the port cover 1 through the rotating shaft 7 and the locking pin 2. The first end of the port cover 1 is connected to the first end of the pipe port outer ring 15 through the rotating shaft, and the port cover 1 is used to rotate relative to the pipe port 5 around the rotating shaft 7 to open or close the pipe port 5 inside the fairing. At least two locking pin mounting frames 10 are arranged at intervals at the second end of the port cover 1, and the two ends of the locking pin 2 are respectively connected to the port cover 1 through the two locking pin mounting frames 10, and the two ends of the locking pin 2 are slidably connected to the two locking pin mounting frames 10. The lock pin 2 is provided with a circle of protrusions in the circumferential direction between the lock pin mounting frame 10, and the spring 3 is sleeved on the lock pin 2, wherein one end of the spring 3 abuts against the protrusion, and the other end of the spring 3 abuts against the lock pin mounting frame near the center of the mouth cover 1, and the spring 3 is used to reset the lock pin 2. The second end of the pipe mouth outer ring 15 is provided with a slide groove 52, and the locking hole 51 is connected to one end of the slide groove 52. The locking hole 51 is used to lock the lock pin 2 when the mouth cover 1 closes the pipe mouth 5, and the slide groove 52 is used to guide the lock pin 2 during the closing process of the mouth cover 1, so that the lock pin 2 can enter the locking hole 51 conveniently.

[0033] Specifically, at present, the air-conditioning interface of the launch vehicle fairing is arranged on the outside of the fairing, and the cover usually adopts a flap structure, and opens or closes the air-conditioning interface on the outside of the fairing. When the ground air-conditioning pipeline is connected to the air-conditioning interface of the fairing, the cover needs to be opened manually. After the ground air-conditioning pipeline is separated from the air-conditioning interface of the fairing, the cover is closed under the action of the torsion spring, and when closed, the cover is restricted from rebounding by the tongue spring. However, after the ground air-conditioning pipeline is separated from the air-conditioning interface of the fairing, there is a risk that the cover cannot be closed. If the cover cannot be effectively closed, the closed environment of the effective load in the fairing will be destroyed during the flight of the launch vehicle, and the cover may fall off under the action of vibration and airflow, forming a hidden danger of excess objects. In addition, the external fairing air-conditioning interface will form a fairing protrusion, affecting the aerodynamic characteristics of the launch vehicle flight.

[0034] In this embodiment, the cover 1 of the air conditioning interface 8 is arranged inside the fairing 8. When the ground air conditioning pipeline is connected to the fairing air conditioning interface, the lock pin 2 is pulled out from the locking hole 51, and the cover 1 rotates around the rotating shaft 7 to open in the direction of the fairing. After the air conditioning pipeline is connected to the fairing air conditioning interface, the cover 1 is supported by the air conditioning pipeline to maintain an open flow state. After the ground air conditioning pipeline is separated from the fairing air conditioning interface, the cover 1 rotates around the rotating shaft 7 toward the pipe mouth 5. When the cover 1 contacts the pipe mouth 5 until the cover completely closes the pipe mouth 5, the lock pin 2 is moved a certain distance toward the center of the cover 1 (for example, the lock pin 2 is manually pulled). At this time, the spring 3 is squeezed and deformed, and the lock pin 2 reaches the locking hole 51 under the guidance of the slide groove 52. That is, when the cover 1 is completely closed, the spring 3 rebounds to reset the lock pin 2, and the end of the lock pin 2 away from the center of the cover 1 enters the locking hole and is locked by the locking hole 51.

[0035] In this embodiment, the spring 3 may be a cylindrical compression spring.

[0036] The air conditioning interface provided in this embodiment rotates toward the inside of the fairing when the cover 1 is opened. Therefore, after the launch vehicle takes off, according to the Bernoulli principle, due to the high-speed flow of gas outside the fairing, the cover 1 can be more closely fitted to the nozzle 5, so that the cover 1 automatically generates a sealing trend. At the same time, the cover 1 and the nozzle 5 are locked by the locking pin 2, which strengthens the sealing state of the cover, reduces the risk of the cover 1 being unable to close, and thus reduces the impact of the cover 1 being unable to seal on the environment of the effective load inside the fairing, thereby improving the reliability of the launch mission. At the same time, the aerodynamic shape of the launch vehicle is optimized, and the flight control capability of the launch vehicle is improved.

[0037] Furthermore, when the rocket is placed vertically and the cover 1 closes the nozzle 5, the first end of the cover 1 is the upper part of the cover 1, and the second end of the cover 1 is the lower part of the cover 1, that is, the lock pin 2 is arranged at the lower part of the cover 1 along the radial direction of the cover 1. After the ground air conditioning pipeline is separated from the fairing air conditioning interface, the cover 1 rotates around the rotating shaft 7 toward the nozzle 5 due to gravity, and the lock pin 2 is squeezed by the nozzle 3 and displaced along the radial direction of the cover 1 toward the center of the cover 1, and the spring 3 is squeezed. The lock pin 2 reaches the locking hole 51 under the guidance of the slide groove 52, and the spring 3 rebounds to reset the lock pin 2 and lock it by the locking hole 51.

[0038] The air conditioning interface provided in this embodiment can realize automatic closing of the air conditioning cover and automatic locking with the pipe opening.

[0039] Furthermore, one end of the locking pin 2 away from the center of the mouth cover 1 is spherical, so that after the locking pin 2 contacts the slide groove 52 , it can be smoothly displaced toward the center of the mouth cover 1 and locked in the locking hole 51 under the guidance of the slide groove 52 .

[0040] Furthermore, the cover 1 is a plate-shaped structure, which can further reduce the overall weight of the fairing.

[0041] like Figure 6 As shown, according to one embodiment of the present invention, the fairing air conditioning interface, in addition to the cover, the pipe mouth, the rotating shaft, the locking pin and the spring, also includes a torsion spring 6. The torsion spring 6 is sleeved on the rotating shaft 7, one arm of the torsion spring 6 is limited by the pipe mouth 1, and the other arm of the torsion spring 6 is limited by the cover 1.

[0042] Specifically, the two arms at the end of the torsion spring 6 can be straight arms or wound into a hook shape. The direction of action of the torsion spring 6 is the direction to limit the opening of the cover 1. After the air-conditioning pipeline is separated from the fairing air-conditioning interface, the cover 1 rotates around the rotating shaft 7 toward the pipe mouth 5 under the action of gravity and the torsion spring 6. When the cover 1 contacts the pipe mouth 5 until the cover 1 completely closes the pipe mouth 5, the locking pin 2 enters the locking hole 51 under the guidance of the slide groove 52, so that the cover 1 closes the pipe mouth 5. According to the fairing air-conditioning interface provided in this embodiment, the cover rotates toward the pipe mouth under the combined action of gravity and the torsion spring, and enters the locking hole for locking under the guidance of the slide groove, so that the cover can automatically close the pipe mouth and be locked by the pipe mouth.

[0043] The present embodiment does not limit the number of torsion springs 6 , and may include two torsion springs, which are symmetrically installed on both sides of the rotating shaft 7 .

[0044] Furthermore, a limiting groove 12 perpendicular to the axial direction of the rotating shaft 7 is provided at the first end of the mouth cover 1, and one arm of the torsion spring 6 is placed in the limiting groove 12 to limit the position of one arm of the torsion spring 6. A support is correspondingly provided at the first end of the outer ring of the pipe mouth 5 to limit the position of the other arm of the torsion spring 6.

[0045] Furthermore, the limiting groove 12 is formed by two straight plates perpendicular to the axial direction of the rotating shaft 7 and arranged at intervals, and the limiting groove 12 can also be a groove perpendicular to the axial direction of the rotating shaft 7. The support 13 is a straight plate parallel to the axial direction of the pipe mouth 5.

[0046] like Figure 5 As shown, according to one embodiment of the present invention, an opening retaining ring 4 is provided at one end of the locking pin 2 away from the edge of the cover 1 , and the opening retaining ring 4 is used to limit the locking pin 2 from escaping from the two locking pin mounting frames 10 to the edge of the cover 1 .

[0047] Specifically, when the cover 1 is opened, the lock pin 2 is pulled out of the locking hole 51, and the spring 3 is squeezed and deformed. After the cover 1 is opened, the spring 3 rebounds, and the opening retaining ring 4 abuts against the lock pin mounting frame to prevent the lock pin 2 from falling out of the edge of the cover 1 under the action of the spring rebound when the cover 1 is reset. The opening retaining ring 4 can be an elastic opening retaining ring for the shaft.

[0048] Furthermore, the lock pin 2 is provided with a retaining ring groove along its axial direction, and the retaining ring groove is a circle of grooves for installing the opening retaining ring 4.

[0049] like Figure 4 As shown, according to one embodiment of the present invention, the lock pin 2 is a stepped shaft with a thin shaft at one end and a thick shaft at the other end. The thin shaft of the lock pin 2 is connected to the lock pin mounting frame close to the center of the mouth cover 1, and the thick shaft of the lock pin 2 is connected to the lock pin mounting frame away from the center of the mouth cover 1. The spring 3 is sleeved on the thin shaft of the lock pin 2. The transition end surface of the thin shaft and the thick shaft of the lock pin 2 forms a bulge.

[0050] Specifically, one end of the spring 3 abuts against a bulge formed by the transition end surface of the thin axis and the thick axis of the lock pin 2, and the other end abuts against the lock pin mounting frame 10 near the center of the cover 1. When the lock pin 2 moves toward the center of the cover 1, the spring 3 is squeezed and deformed, and when the lock pin 2 is released, the lock pin 2 is reset under the action of the spring 3.

[0051] Furthermore, ear plates 11 are respectively provided on both sides of the first end of the mouth cover 1 and both sides of the first end of the pipe mouth 5 , for connecting the mouth cover 1 and the pipe mouth 5 via the rotating shaft 7 .

[0052] The present invention is described by taking the pipe opening and the mouth cover as a circular shape as an example, but this does not limit the scope of the present invention. For example, the through hole and the mouth cover of the pipe opening are polygonal. Similarly, the present invention does not limit the connection relationship between the pipe opening and the fairing, such as the pipe opening and the fairing can be integrally formed.

[0054] In another aspect, the present invention provides a launch vehicle, comprising the above-mentioned air conditioning interface. The launch vehicle provided by the present invention has corresponding technical effects because it comprises the above-mentioned air conditioning structure.
