The front and rear plates 70 and 74 are opened to their maximum angle and inserted into the grooves of the mooring lock base plate 69. They are then closed to wrap around the large stud 72 and closed to their minimum angle. A stop pin 73 is inserted through the through-hole between the front and rear plates 70 and 74 to prevent the front and rear plates from falling off the large stud 72.

[0066] The main working process of the mooring release mechanism is as follows:

[0067] 1) The initial installation state of the mechanism is shown in Figures 1 and 2.

[0068] 2) Fasten the assembly to the corresponding position of the cargo platform with bolts and nuts.

[0069] 3) When the mechanism is initially tethered, the longitudinal rod assembly is pulled backward, and the transverse rod assembly slides to the sides, resisting the tension of the tether release strap on the vise assembly. The springs on both the longitudinal and transverse rods are compressed. During an airdrop, the mechanism triggers the pyrotechnic cutter in the longitudinal rod limit assembly, causing the compression spring to rebound, causing the longitudinal rod assembly to move forward. The transverse rod assembly then moves laterally inward from the cargo platform, opening the vise assembly jaws, loosening the tether release strap, and allowing the left and right levers of the tether lock to open and fall, releasing the tethers between the airdrop equipment and the cargo platform.

[0070] The present invention can realize simultaneous actuation in multiple points and directions by increasing or decreasing the number of translation cams and the number of cross bars on the longitudinal bars.

[0071] The present invention is primarily used in my country's airdrop sector. It can tether and secure an airdrop system to airdrop equipment during air transport, and achieve mid-air separation of the airdrop system and airdrop equipment after leaving the aircraft. Unlike other airdrop systems, this airdrop system requires not only that the airdrop system and airdrop equipment be tied and secured during air transport, but also that the airdrop equipment and airdrop system be separated mid-air after leaving the aircraft.

[0072] The present invention limits the installation position of the longitudinal rod and cross bar assembly on the cargo platform through the support seat; determines the overall height limit of the longitudinal rod and cross bar assembly through the installation position of the airdrop boat on the cargo platform; determines the mooring bundling style through the reserved position of the cargo platform pull ring assembly, the vise assembly and the mooring lock on the airdrop boat to achieve mooring and fastening of the airdrop system and the airdrop equipment during air transportation; determines the initial force value of the longitudinal rod through the longitudinal rod limiting assembly; and drives the entire set of mooring release mechanisms to be released through the actuation of the pyrotechnics of the longitudinal rod limiting assembly, thereby solving the problem of separation in the air after airdrop.

[0073] The present invention has been tested on the ground nearly 50 times, and the test process is good. The spring force value is within the designed range. The four points are actuated simultaneously and quickly with high reliability. There are no faults such as poor actuation and jamming, and the expected effect has been basically achieved.
