Description
Technical field
The utility model belongs to rocket radome fairing surface separation test buffering recovery technology field, is specifically related to a kind of large-scale combined recovery air bag.
Background technology
Large Launch Vehicle is before target range is launched, corresponding ground validation test must be carried out, along with the develop rapidly of China's aerospace industry, require more and more higher to the carrying capacity of carrier rocket, the overall dimensions of rocket is also increasing, in order to reduce itself weight, improve rocket payload carrying capacity, the structural requirement of rocket is more and more thinner.Therefore, carry out on ground, in large-scale separation test, very easily may causing the damage of product, destruction.
Surface separation for past larger shape radome fairing reclaims, and the methods such as sponge kind foamed material, recycling network are laid in domestic usual employing, has shown that some reclaim empirical parameter.But namely the method exists the buffering overload difficulty not easily regulated bigger than normal, there is again recovery body and the danger that bounce-back causes secondary pulse occurs, and need the padded coaming being equipped with a large amount of thickness in testing ground, waste time and energy.
Along with the development of China's aerospace industry, the size that product is reclaimed in surface separation test is increasing, and weight is more and more heavier, and the rigidity of structure is more and more lower, and separating rate is then increasing, and therefore, design adopts brand-new recovery scheme to become a brand-new research field.
Summary of the invention
The purpose of this utility model proposes a kind of ultra-large type Combined gas-bag buffering retracting device being easy to regulate, and can meet the safe retrieving of dome structure diameter being about to more than 5m, highly about more than 20m, weight about 2 tons, speed about 10 ~ 15m/s.
To achieve these goals, the technical solution of the utility model is, a kind of large-scale combined recovery air bag, comprises long main gasbag and auxiliary balloon; Wherein, long main gasbag entirety is cuboid, is divided into 10 air chambers; Long main gasbag middle gas chamber one side bottom has a pressure tap, and the side bottom of side air chamber has a main gasbag air-filled pore; The direction of recession both sides of long main gasbag are respectively evenly equipped with 10 steam vents, and width both sides are respectively evenly equipped with 2 steam vents; Auxiliary balloon is cuboid, is divided into 4 air chambers, and the side bottom of one of them air chamber has an auxiliary balloon air-filled pore; The direction of recession both sides of auxiliary balloon are respectively evenly equipped with 4 steam vents, and width both sides are respectively evenly equipped with 2 steam vents; All separated by air chamber partition wall between the air chamber of long main gasbag and auxiliary balloon, the air chamber partition wall between adjacent air cells has through hole; All steam vents are all in the centre position of main gasbag or auxiliary balloon height.
Described steam vent comprises tack coat and exhaust diaphragm; Wherein, steam vent is arranged on the tapping of envelop materials, and tack coat is bonded on the outer wall of envelop materials tapping, and exhaust diaphragm is bonded at envelop materials tapping by tack coat.
Described envelop materials tapping is evenly equipped with a circle and beats buckling rope.
Described envelop materials adopts the Kev of 9000N/5cm to draw high strength fiber material.
Described tack coat width is 0.5cm.
The utility model solves the buffer problem of large-scale buffer structure, by regulating exhaust outlet quantity conveniently can regulate buffering overload time history, and, effectively control buffering peak value overload.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of large-scale combined recovery air bag, comprises long main gasbag and auxiliary balloon, as shown in Figure 1, 2; Wherein, long main gasbag entirety is the cuboid of long 12.5m, wide 7m, high 2.6m on direction of recession, is divided into 10 air chambers 7; Long main gasbag middle gas chamber 7 one side bottom has a pressure tap 5, and the side bottom of side air chamber 7 has a main gasbag air-filled pore 6; The direction of recession both sides of long main gasbag are respectively evenly equipped with 10 steam vents 2, and width both sides are respectively evenly equipped with 2 steam vents 2; Auxiliary balloon is the cuboid at the long 5m of direction of recession, wide 7m, high 2.6m, is divided into 4 air chambers 7, and the side bottom of one of them air chamber 7 has an auxiliary balloon air-filled pore 4; The direction of recession both sides of auxiliary balloon are respectively evenly equipped with 4 steam vents 2, and width both sides are respectively evenly equipped with 2 steam vents 2; All separated by air chamber partition wall 1 between the air chamber 7 of long main gasbag and auxiliary balloon, the air chamber partition wall 1 between adjacent air cells 7 has through hole 3; All steam vents 2 are all in the centre position of main gasbag or auxiliary balloon height.
Steam vent 2 as shown in Figure 3, comprises tack coat 10 and exhaust diaphragm; Wherein, steam vent 2 is arranged on the tapping of envelop materials 9, and tack coat 10 is bonded on the outer wall of envelop materials 9 tapping, and exhaust diaphragm is bonded at envelop materials tapping by tack coat 10.
Envelop materials 9 tapping is evenly equipped with a circle and beats buckling rope 8, and its effect is when the Rupture of Membrane pressure of exhaust diaphragm is too low, and by beating buckling rope 8, exhaust diaphragm can be tied up to the tapping of envelop materials 9, what realization cushioned stablizes.Envelop materials 9 adopts the Kev of 9000N/5cm to draw high strength fiber material.According to tack coat 10 intensity, determine that tack coat 10 width is 0.5cm, thus setting pressure at expulsion is 0.01 atmospheric pressure.
