Airdrop material deceleration streamer

Abstract

The invention relates to a deceleration streamer for airdrop materials, comprising a streamer main body and a blower pocket made of special spinning materials. The head end of the streamer main body can be connected with airdrop materials, and a cut corner is left at the tail end, and the blower pockets are alternately sewn on the streamer belt in turn. On the front and back of the main body, the first blowing pocket has a distance K from the head end of the streamer main body, and the blowing pocket has an opening in the direction of the head end of the streamer main body; L is determined according to the weight and falling speed requirements of the airdropped materials, 4≤the length of the main body of the streamer L / the width of the main body of the streamer W≤75; 20°≤the angle θ of the tail end of the main body of the streamer≤60°. The entire air-dropping material drop point of the deceleration streamer is less affected by the wind, the vibration angle of the air-dropped material is small, the packaging is simple, and the air-drop is fast.

Description

technical field [0001] The invention belongs to the field of airdrops, and in particular relates to an airdrop material deceleration streamer. Background technique [0002] Airdrops of materials are generally completed by helicopters, fixed-wing transport aircraft or bombers. It is necessary to comprehensively consider the carrying capacity, transportation distance, speed, weather conditions and terrain conditions to select the above-mentioned airdrop carrier. Among them, helicopter airdrops can be divided into parachute or hovering Drop directly, fixed-wing transport aircraft mainly perform parachute airdrops, and bombers mainly perform airdrops with parachute bombs. Helicopters drop directly after hovering, resulting in a faster landing speed, which may damage the airdropped supplies. However, airdrops with umbrellas have the following disadvantages: 1) The wind direction is uncertain - the parachute is greatly affected by the air flow, and the landing of the supplies cann...

Problems solved by technology

Helicopters drop directly after hovering, resulting in a faster landing speed, which may damage the airdropped supplies. However, airdrops with umbrellas have the following disadvantages: 1) The wind direction is uncertain - the parachute is greatly affected by the air flow, and the landing of the supplies cannot be controlled after airdropping If you cannot land in a better airdrop landing site, it may cause damage to the airdropped materials; 2) It is difficult to parachute - if you want to airdrop heavy materials, you need a special parachute Chassis and control system; 3) The cost of parachute is relatively high - the manufacturing cost of the parachute is relatively high, and it cannot be recycled again after being airdropped with the materials, resulting in high cost of parachute
