Example Embodiment

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See Figure 1-4 This specific implementation is realized by adopting the following technical solution, which includes a top cover 1 and a cushion pad 2 connected to it. The top cover 1 and the cushion pad 2 are mutually engaged and fixed by a zipper 3, and are attached to the cushion pad 2. A flash 11 extends outward from the outer profile of the flash 11, the flash 11 is provided with an air-collecting hole 13, and a reduction parachute 14 is provided around the flash 11 for sealing by fitting the edges. The other side of the top cover 1 is provided with a zipper 3, And there is an air collecting hole 13 on the periphery of the zipper ...

Abstract

The invention discloses an extreme low-altitude drop device which comprises a top cover and a cushion connected with the top cover. The top cover is intermeshed and fixed with the cushion through zippers, and a fin extends out of the top cover along the external contour of the cushion. Air accumulating holes are formed in the fin, and a speed reducing umbrella which is fitted with an edge of the fin to seal and fix is arranged around the fin. A zipper is arranged on the other surface of the top cover, and air accumulating holes are formed in the periphery of the zipper. The whole cushion is in a hollow structure, a concave-inward material groove is formed in the top surface of the cushion, intermeshed zippers are arranged on the surrounding edges of the cushion, and a shock absorption device is arranged on the bottom surface of the cushion. The extreme low-altitude drop device can effectively realize extreme low-altitude air drop under harsh environmental conditions such as high wind, rainfall, complex terrain conditions and the like, can avoid the influence of disturbance airflow, can realize fixed point precise air drop to fill the domestic blank in the field, and is also beneficial to recovery for secondary utilization after air drop.

Description

technical field [0001] The invention relates to the field of airdrop technology, in particular to an ultra-low altitude drop device. Background technique [0002] In emergency rescue, disaster relief or wartime, the transportation of necessities such as food, daily necessities, medical equipment and ordnance is crucial, among which the airborne airdrop method is widely used because of its fast characteristics. However, in various harsh and complex environments, high-altitude airdrop equipment will be affected by turbulent airflow, making it difficult to achieve precise airdrops at fixed points, and materials airdropped to the ground will also be subject to greater impact, which can easily cause damage or shock damage to the goods The phenomenon. [0003] However, if ultra-low-altitude delivery is used, although precise airdrops can be effectively achieved, due to the complex terrain and turbulent airflow in the low-altitude environment, the parachute often does not open in ...
