Retractable and foldable helicopter short-wing weapon rack device

Abstract

The present invention provides a retractable and foldable helicopter stub-wing weapon pylon device, comprising a plurality of modular stub wings connected by a connecting structure. The modular stub wings contain a weapon pylon body, a weapon pylon rotating device, and a movable hatch structure. The weapon pylon rotating device controls the rotation of the weapon pylon body. When the weapon pylon body rotates to its highest position, it is stored within the modular stub wings. When the weapon pylon body rotates to its lowest position, it extends through the movable hatch structure and out from under the modular stub wings. The present invention enables an armed helicopter to select the number of stub wings and weapon pylons according to different mission requirements. By designing the rotation and retraction of the weapon pylons and the stub-wing hatch switch, the weapon pylons can be retracted into the stub wings and modularly folded after the armed helicopter has launched weapons, thereby improving the maneuverability and flight performance of the armed helicopter in performing subsequent missions.

Description

Technical Field

[0001] The invention relates to the field of helicopter weapon launching devices, in particular to a retractable and foldable helicopter short-wing weapon hanging rack device. Background Art

[0002] Attack helicopters are ultra-low-altitude firepower platforms. Their combination of powerful firepower and flight performance makes them irreplaceable in modern warfare. To enhance the lethality of combat aircraft, modern attack helicopters often utilize pylons to carry various lethal weapons. These pylons are typically mounted beneath the stub wings on either side of the fuselage. The primary function of these pylons is to carry and deploy onboard weapons. However, when deploying weapons or performing non-offensive missions such as transport or airdrops, the pylons and extra-long stub wings create drag on the helicopter's flight, reducing its flight performance and maneuverability. Summary of the Invention

[0003] In order to solve the problems of the prior art, the present invention provides a retractable and foldable helicopter short-wing weapon rack device, which can not only meet the functions of carrying and dropping weapons when the armed helicopter performs attack missions, but also reduce the excess resistance generated by the short-wing rack on the subsequent flight of the armed helicopter.

[0004] The present invention provides a retractable and foldable helicopter short-wing weapon rack device, comprising a plurality of modular short wings connected by a connecting structure. A weapon rack body, a weapon rack rotating device, and a movable hatch structure are arranged in the modular short wings. The weapon rack rotating device controls the rotation of the weapon rack body. When the weapon rack body rotates to the highest position, it is stored in the modular short wings. When the weapon rack body rotates to the lowest position, it passes through the movable hatch structure and extends below the modular short wings.

[0005] The weapon hanger body comprises a movable hanger, hanger guide rails, and anti-sway stoppers. The movable hanger comprises a hanger, a rotating motor, and a hanger shaft. The hanger is connected to the shaft via the rotating motor, which controls the hanger's rotation about the shaft. The hanger body has guide rails on both sides, and the shaft is mounted on each side, allowing the shaft to move up and down along the rails. Two anti-sway stoppers are located on either side of the lower end of the weapon hanger body. When the shaft reaches its uppermost position, the rotating motor controls the hanger's rotation. When the weapon's lifting ring contacts the base of the hanger, the hanger locks, and the two anti-sway stoppers clamp the weapon.

[0006] The modular short wing includes a skin, an I-beam, a U-beam, and a rotating beam guide rail. The middle section of the modular short wing is horizontal and the two ends are streamlined. The I-beam is located in the middle of the modular short wing, and the U-beam is distributed at both ends of the modular short wing. Four rotating beam guide rails are distributed on both sides of the middle section of the I-beam and the U-beam.

[0007] The rack rotating beam is connected to the weapon rack body, and the rotation of the weapon rack body is controlled by a motor. The two ends of the rack rotating beam are respectively connected to the rotating beam guide rails, and the rack rotating beam can move left and right along the rotating beam guide rails.

[0008] The fixed support rod is fixedly connected to both sides of the I-beam of the modular short wing. When the rack rotating beam rotates the weapon rack body to the inside of the modular short wing, the rotating motor controls the rotation of the suspension hook, and the suspension hook passes through the fixed support rod, and the suspension hook rotation is locked.

[0009] The movable door structure includes a door, a door fixed shaft, a door connecting block, a first door rotation motor, a hydraulic connecting rod, a second door rotation motor, a door rotation shaft, and a door fixed block. Both ends of the door fixed shaft are fixedly connected to the short wing skin through two door connecting blocks, and the door fixed block is fixedly connected to the door; one end of the hydraulic connecting rod is connected to the first door rotation motor, and the other end is connected to the second door rotation motor; the first door rotation motor can control the hydraulic connecting rod to rotate relative to the door fixed shaft, and the second door rotation motor can control the door rotation shaft to rotate.

[0010] The connection structure includes a hinge and a control motor. The hinge hinges are respectively fixedly connected to the outer side of the module outer short wing skin. The control motor realizes the folding of the modular short wing by controlling the rotation of the hinge center axis.

[0011] The beneficial effects of the present invention are:

[0012] 1. Through the design of rotating and retractable weapon pylons and stub wing door switches, the weapon pylons on attack helicopters can be retracted and extended. When the attack helicopter is performing attack missions, after missiles are released, the weapon pylons can be retracted into the stub wings, and the modular stub wings can be folded. Compared to traditional fixed weapon pylons, this improves the maneuverability and flight performance of the attack helicopter during subsequent missions.

[0013] 2. The modular stub wing design allows the helicopter to select the number of stub wings according to mission requirements, allowing it to carry varying amounts of weapons and equipment. When performing non-attack missions, the helicopter can operate without the modular stub wings, significantly reducing flight drag. When performing attack missions, the modular stub wings can be installed as needed. After weapons are deployed, the stub wings can be folded, reducing the drag caused by rotor downwash during flight.

[0030] Figure 5 In the figure, the left and right sides respectively represent the open and closed states of the hatch 18. When the command to retract or close the weapon rack body 3 is received, the first hatch rotation motor 21 first drives the hydraulic connecting rod 22 to rotate. While rotating to a certain angle, the second hatch rotation motor 23 drives the hatch rotation axis to rotate relative to the hydraulic connecting rod 22. Finally, through the cooperation of the first hatch rotation motor 21 and the second hatch rotation motor 23, the hatch 18 is opened and parallel to the short wing skin 14. The hydraulic connecting rod 22 is extended to make the hatch 18 fully open, and the state from the closed right side of the figure to the open left side can be realized; conversely, the process is reversed.
