Description

Technical Field

[0001] This utility model patent relates to the field of airdrop training, and in particular to a multi-aircraft heavy-duty airdrop training simulation device. Background Art

[0002] Heavy equipment airdrop is an important part of material airdrop. After the heavy equipment airdrop materials are loaded onto the aircraft, they need to be fixed together with the towing parachute and the towing parachute rope to prepare for the heavy equipment airdrop. During the airdrop, the towing parachute detaches from the transport aircraft and opens in the air, towing the unfixed heavy equipment airdrop materials away from the aircraft.

[0003] Securing and detaching the tow parachute from a transport aircraft is a key training task. However, training on a transport aircraft is expensive and limited, and there is currently a lack of low-cost, flexible training simulators. Furthermore, the tow parachute is fixed in different locations on different transport aircraft. Some are located on the roof of the cabin, inside the drop port, such as on the Y-8 and Y-9 transport aircraft; others are located on the inside surface of the drop door, with the top of the door hinged to the cabin roof, such as on the Y-20 transport aircraft. When the drop door flips upward and opens, the tow parachute pack rests on the horizontal underside of the door.

Specifically, in this embodiment, if Figure 3 As shown, the locking unit includes an arc-shaped plate 26 fixed in the installation box and a plug-in type electromagnetic lock 27 plugged into the arc-shaped plate, and the plug-in type electromagnetic lock is fixed in the installation box.

[0034] The parachute mounting mechanism also includes a tensioning mechanism mounted on the mounting box. This tensioning mechanism comprises a lead screw 19 extending along the mounting box's longitudinal axis, at least two screw nuts 20 mounted on the lead screw, a connecting rod 22 hingedly secured to the screw nuts, at least two guide sleeves 23 secured to the bottom of the mounting box, and at least two tensioning forks slidably engaged with the guide sleeves. The tensioning forks include a fork 24 at their lower ends and a rod 25 connected to the fork. The rod slidably engages the corresponding guide sleeve. The other end of the rod is hingedly connected to the connecting rod. In the initial position, the connecting rod is tilted. The lead screw extends through the mounting box and is axially positioned and rotatably connected to both ends of the mounting box via bearing blocks (not shown). A handwheel 21 is secured to the outer end of the lead screw to facilitate manual tightening of the lead screw. The screw nut 20 is located within the mounting box. At least two restraining rods 14 for restraining the parachute are positioned on either side of the parachute mounting mechanism. To prevent interference, in this embodiment, a locking unit is positioned below the tensioning mechanism and secured to the mounting box via booms 17 and 18 or a connecting plate. In other embodiments, the locking unit may also be provided on one side of the tightening mechanism.

[0035] In this embodiment, the driving mechanism includes a power source that outputs linear motion and a power source fixing frame 7 fixed on the top of the door-shaped frame and extending backward from the door-shaped frame.

The bottoms of the portal frame and the side frames are equipped with rollers 2 and 12 to facilitate the movement of the multi-aircraft heavy-duty airdrop training simulator. The side frames include multiple removable, hinged square steel tubes and side baffles 3 at the bottom. After use, they can be easily folded and stored to reduce space usage.

The tow parachute fixing mechanism is fixed on the inner surface of the release door. When the release door is flipped to the horizontal position, the release door is fully opened, and the tow parachute is located on the lower surface of the release door, which can be used to simulate the training of tow parachute fixing and detaching on the Yun-20 transport aircraft. It is simple and practical; the tow parachute fixing mechanism is fixed on the lower surface of the top of the door-type frame and the inner surface of the release door, which can simulate the training of tow parachute fixing and detaching on the Yun-9 transport aircraft, as well as the training of tow parachute fixing and detaching on the Yun-20 transport aircraft. It is suitable for multi-aircraft heavy-duty airdrop training simulation and is more flexible to use.

[0038] A slotted hole is located on the bottom of the mounting box, directly opposite the latch, to facilitate direct attachment of the parachute lanyard to the latch. After the latch unit locks the parachute lanyard, the tensioning mechanism's screw is rotated, driving the nut axially on the screw. This pushes the tilting screw's pressure rod downward along the guide sleeve, causing the tensioning fork to move downward, engaging and pressing the parachute pack downward, securing it in place. At least two restraining rods are positioned on either side of the parachute securing mechanism to restrain the parachute pack horizontally. The power source mounting bracket extends rearward from the gate-shaped frame, allowing the two ends of the power source to form an angle with the vertical when the launch door is closed, facilitating opening and closing of the launch door. At least two restraining rods are positioned on either side of the parachute securing mechanism to restrain the parachute pack horizontally. The power source mounting bracket extends rearward from the gate-shaped frame, allowing the two ends of the power source to form an angle with the vertical when the launch door is closed, facilitating opening and closing of the launch door.

[0039] Example 2

[0040] Different from the above embodiment, Figure 4 、 Figure 5 As shown, the lock unit includes a rotary door lock 30 and a plunger electromagnetic lock secured within a mounting box. Both the rotary door lock 30 and the plunger electromagnetic lock are commercially available products, such as the R4 rotary door lock, and are not described in detail here. The plunger electromagnetic lock is connected to the unlocking tab at the rear of the rotary door lock via a connector. The plunger electromagnetic lock is positioned parallel to the rotary door lock and can be located inside or outside the mounting box. In this embodiment, a U-shaped steel pipe is secured to the outer surface of the delivery door 15 to form a rectangular groove. The mounting box is secured within the groove, allowing the mounting box to be embedded within the inner surface of the delivery door 15. The plunger electromagnetic lock is secured to one side of the U-shaped steel pipe.

[0041] like Figure 4As shown, the tensioning mechanism includes a lead screw arranged along the front-to-back direction of the mounting box, at least two screw nuts mounted on the lead screw, a pair of parallel guide plates 32 fixed to each screw nut, at least two guide sleeves fixed to the bottom of the mounting box, and at least two tensioning forks that slidably engage with the guide sleeves. The tensioning forks include a fork head at the lower end and a rod connecting the fork head. The rod is slidably engaged in the corresponding guide sleeve. The guide plate has an inclined guide groove (not shown). The other end of the rod is fixed to a crossbar, and the two ends of the crossbar are engaged in the corresponding inclined guide groove. Specifically, the two ends of the crossbar have bearings that roll in the inclined guide groove. The lead screw is inserted into the mounting box and is axially positioned and rotatably arranged with the two ends of the mounting box via a bearing seat. The screw nut is located in the mounting box. A fixed plate 29 with a hole for fixing the parachute rope is also provided in the rectangular groove.

[0042] In this embodiment, the lock unit is structured so that a remote-controlled, plug-in electromagnetic lock can be used to rotate the unlocking plate, which in turn unlocks the rotary door lock. To lock the parachute lanyard, the latching claw of the rotary door lock is simply pressed to the locked position. After the lock unit locks the parachute lanyard, the tensioning mechanism's lead screw is rotated, which drives the nut axially on the lead screw, driving the guide plate axially along the lead screw. The crossbar, driven by the oblique guide groove, drives the plug rod outward, causing the tensioning fork to move downward, forcing it to engage and press downward on the parachute pack, thereby limiting and fixing the pack. To release the tension, the mechanism simply rotates in the opposite direction.
