Description

Technical Field

[0001] The present application relates to the field of airdrop devices, and in particular, to a device and method for automatically adjusting the landing direction of an airdrop system. Background Art

[0002] Airdrop systems, especially heavy-duty airdrop systems, are greatly affected by factors such as wind, terrain, and landing speed during airdrop landing. Rollovers often occur, which seriously affects the progress of airdrop operations. At present, the main methods to solve the problem of airdrop rollovers include landing attitude adjustment, mechanical anti-rollover leg structures, and anti-rollover airbag structures. These devices and methods can prevent airdrop rollovers under certain conditions, but they also have certain limitations. Landing attitude adjustment methods include directional anti-rollover and active attitude adjustment. In directional anti-rollover systems, the cable will lose its attitude adjustment function after being relaxed; active attitude adjustment involves an electric attitude adjustment device, and the operation procedure is relatively complicated, and the attitude adjustment effect cannot meet the use requirements; the mechanical anti-rollover legs are heavy and have poor versatility, which results in greater limitations in actual use; the performance of the anti-rollover airbag structure needs to be verified by experiment.

[0029] The features and performance of the device and method for automatically adjusting the landing direction of an airdrop system of the present application are further described in detail below in conjunction with the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3As shown, an embodiment of the present application provides a device for automatically adjusting the landing direction of an airdrop system, which includes a parachute 110 and a connecting frame 200 connected to an airdrop object 100, the connecting frame 200 is connected to a wire reel 120 and a cable storage bag 130, the cable storage bag 130 is connected to a sealing rope 160 for closing it, the parachute 110 is connected to a delay cutter 150 through a hair pull rope 140, the sealing rope 160 passes through the delay cutter 150, the wire reel 120 is connected to and reels one end of a cable 170, the other end of the cable 170 extends into the cable storage bag 130 and is sequentially connected to a counterweight 190 and a ground anchor 180 arranged at intervals, the ground anchor 180 is provided with a pointed ground insertion portion 181 for inserting into the ground; when the parachute 110 is opened, the hair pull rope 140 is used to activate the delay cutter 150 to cut off the sealing rope 160 and open the cable storage bag 130, so that the ground anchor 180 falls and is inserted into the ground for fixing. In this embodiment, the wire reel 120 is of prior art, which includes a wire reel housing, a wire reel roller rotatably connected to the wire reel housing, and a winding spring respectively connected to the wire reel roller and the wire reel housing. One end of the cable 170 is sleeved on and connected to the wire reel roller. When the cable 170 is pulled out of the wire reel 120, it drives the wire reel roller to rotate and stretches the winding spring. The wire reel 120 has two winding states: the first is that the cable 170 can be wound in and pulled out; the second is that the cable 170 can be wound in but not pulled out. At this time, the cable 170 is completely pulled out of the wire reel 120, and the winding spring is stretched to the limit.

[0031] like Figure 4 and Figure 5 As shown, the embodiment of the present application also provides a method for automatically adjusting the landing direction of an airdrop system, which is performed using the above-mentioned device for automatically adjusting the landing direction of an airdrop system, and includes the following steps:

[0032] Before airdrop, the parachute 110 and the connecting frame 200 are connected to the airdrop object 100, the cable reel 120 and the cable storage bag 130 are connected to the connecting frame 200, the cable 170 wound up on the cable reel 120 is pulled out completely and then inserted into and stored in the cable storage bag 130 together with the counterweight 190 and the anchor 180, the cable storage bag 130 is closed with the sealing rope 160, the pulling rope 140 is connected to the parachute 110 and the delay cutter 150 respectively, the delay cutter 150 is fixed to the cable storage bag 130, and the sealing rope 160 is passed through the delay cutter 150;

[0033] During airdrop, the parachute 110 is inflated and opened, so that during the opening process of the parachute 110, the pull rope 140 is pulled to drive the delay cutter 150 to start, so that the delay cutter 150 cuts the sealing rope 160 and opens the cable storage bag 130, so that the cable 170, the counterweight 190, and the anchor 180 in the cable storage bag 130 are released and fall down. Before the counterweight 190 and the anchor 180 fall to the ground, the reeling tension of the reel 120 is less than the sum of the weights of the cable 170, the counterweight 190, and the anchor 180, and the reel 120 is 0 cannot reel in the cable 170, after the counterweight 190 and the anchor 180 land, the tip ground-inserting part 181 of the anchor 180 is inserted into the ground and fixed, the reeling tension of the reel 120 is greater than the weight of the cable 170, the counterweight 190 and the anchor 180 are anchored on the ground, the reel 120 reels and tightens the cable 170 that is loosened as the airdrop object 100 descends, and combined with the tension generated by the parachute 110 under the influence of wind, the airdrop system has a stronger anti-rollover performance when landing, and the direction is consistent with the wind direction, thereby reducing the rollover probability of the airdrop system.

[0034] The device and method for automatically adjusting the landing direction of an airdrop system provided in the embodiment of the present application are as follows: a parachute 110, a reel 120 and a cable storage bag 130 are arranged on an airdrop object 100; a cable 170 connected to the reel 120 is connected to a counterweight 190 and a ground anchor 180, and then stored in the cable storage bag 130 and sealed and fixed with a sealing rope 160; then, when the parachute 110 is opened at landing, the delay cutter 150 is activated by pulling the hair rope 140 to cut the sealing rope 160 and open the cable storage bag 130, so that the counterweight 190 and the ground anchor 180 fall down and are inserted into the ground for fixation; and the reel 120 is used to reel and tighten the cable 170 that is loosened as the airdrop object 100 descends, so that the airdrop system has strong anti-rollover performance when landing, and the direction is consistent with the wind direction, reducing the probability of the airdrop system rolling over. The device and method have the advantages of simple structure, easy operation, adaptability to airdrop objects of different sizes, and wide application range.

[0035] The other end of the cable 170 extends into the cable storage bag 130 and is connected to the counterweight 190 and the anchor 180 arranged at intervals in sequence. The counterweight 190 can be used to ensure that the anchor 180 is not pulled off the ground after landing. The anchor 180 is provided with a sharp ground-inserting portion 181 for inserting into the ground. The gravity of the counterweight 190 and the anchor 180 can be used to insert the sharp ground-inserting portion 181 into the ground to fix the anchor 180 to achieve the ground gripping function, and one end of the cable 170 is anchored on the ground to adjust the landing direction.

[0036] In other optional embodiments, the delayed cutter 150 may not be provided, but the hair pull rope 140 may be directly connected to the sealing rope 160, and the parachute 110 may be opened when landing, and the sealing rope 160 may be pulled by the hair pull rope 140 to loosen and open the cable storage bag 130, so that the counterweight 190 and the ground anchor 180 may fall down and be inserted into the ground for fixation.

[0037] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
