Description

Technical Field

[0001] The utility model relates to an airbag type water surface stable launching mechanism, belonging to the technical field of mechanical design and manufacturing. Background Art

[0002] At present, fixed launch tubes are used for surface launch of aircraft, that is, the launch tubes are fixedly constrained to ensure the stability of the aircraft during launch. However, this launch method requires the entire launch system to be coupled with the water platform, such as ship-borne launch. The design and manufacture of the launch system coupled with the platform leads to increased launch costs. At the same time, the position can only be transferred by the movement of the platform, which is not flexible. Unconstrained launch tubes have great flexibility. Multiple launch tubes can be deployed to the designated location by submarines, air transport, etc. to achieve multi-point launch. However, considering that the reaction force generated by the launch of the unconstrained launch tube when launching the aircraft will cause the launch tube to become unstable, deflect or sink, thereby increasing the disturbance of the aircraft leaving the tube, resulting in the launch failing to achieve the expected design effect.

[0003] Therefore, it is urgent to develop a surface launch stabilization device to increase the stability of the aircraft surface launch and realize the launch of the aircraft on the water surface with an unconstrained launch tube. Utility Model Content

[0007] The launching tube comprises a tube body, a front cover and a rear cover which are connected in sequence, and the interiors of the tube body, the front cover and the rear cover form a sealed space.

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] Example 1

[0020] like Figures 1 to 5 As shown, an airbag-type surface-stabilized launching mechanism comprises a launching tube and a cable connector 10; an aircraft is loaded in the launching tube, and the cable connector 10 is connected to a power source of the aircraft; an airbag 4, an air bleed nozzle 5 and an inflation valve 6 are bonded to the side wall of the launching tube, and the air bleed nozzle 5 is connected to the airbag 4; the airbag 4 is connected to the side wall of the launching tube through an airbag clamping mechanism 8, and its position is adjustable, and the air bleed nozzle 5 is connected to the inside of the launching tube through an electromagnetic valve 7.

[0021] The launching tube comprises a tube body 1, a front cover 2 and a rear cover 3 which are connected in sequence. The interiors of the tube body 1, the front cover 2 and the rear cover 3 form a sealed space, and the internal and external dimensions of the space are adjustable.

[0022] The cylinder 1, the front cover 2 and the rear cover 3 are connected and fixed to each other via a sealing ring and fastening bolts.

[0023] The airbag holding mechanism 8 includes a wrapping belt 12 , and the airbag 4 is tightened by the wrapping belt 12 ; both ends of the wrapping belt 12 are connected to connecting plates 11 , and the connecting plates 11 are connected by explosive bolts 9 .

[0024] The 11 is connected to the side wall of the launch tube.

[0025] Preferably, the bonding position of the airbag 4 needs to ensure that the center of buoyancy is higher than the center of mass of the launch tube and the fully loaded aircraft, and the air path is controlled by the electromagnetic air valve 7.

[0026] Preferably, the pressure in the launch tube is related to the expansion requirement of the airbag 4, and the pressure is adjustable.

[0027] Preferably, the weight of the launch tube is inversely correlated with the buoyancy, and the airbag 4 is inflated mainly to increase the buoyancy and the contact area with the water surface, and the inflation size of the airbag 4 is adjustable.

[0028] Example 2

[0029] The aircraft is loaded in the launch tube, and a certain air pressure is filled into the launch tube through the inflation valve 6 (the inflation pressure value is calculated according to the expanded volume of the airbag 4). After the launch tube is transported to the specified position on the water surface, the electrical signal is remotely controlled to detonate the explosive bolt 9, and the left and right connecting plates 12 in the airbag clamping mechanism 8 are loosened. The wrapping belt 12 releases the clamping constraint on the airbag 4 and detaches, exposing the airbag 4. Then the electromagnetic valve 7 is controlled to open, and the air pressure in the launch tube is filled into the airbag 4 through the air bleed nozzle 5. The airbag 4 begins to expand, and after the airbag 4 expands to the specified requirement, the aircraft is ignited and launched. The inflated airbag 13 increases the sinking water resistance of the launch tube when the aircraft is launched, ensuring that the launch tube is stable on the water surface when the aircraft is launched, without sinking or flipping, thereby achieving stable launch of the aircraft on the water surface.

[0030] In summary, the beneficial effects of the present invention are:

[0031] ① The pure mechanical structure has high reliability, good integrity and light weight. The entire mechanism is mainly fixed by bolts and adhesives, which is easy to install and adjust;

[0032] ② Because the size of the launch tube can be adjusted according to the structural requirements of the aircraft, it can meet the requirements of different types of aircraft;

[0033] ③ The launch requirements can be met by adjusting the size of the airbag expansion, the buoyancy of the airbag and the contact area with the water surface;

[0034] ④ It meets the requirements of unconstrained launch tubes for launching different types of aircraft on water. It has a simple and stable structure, can increase the stability of aircraft surface launch, and realize the launch of aircraft on the water surface by unconstrained launch tubes.
