Embodiment Construction

[0014] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention provides a schematic diagram of the flange structure suitable for underwater electromagnetic ejection devices. This structure is used to provide an interface for installing and fixing the launch tube of the aircraft when the launching device is stored and transported, and it is installed and fixed on the launching device. on the device. The structure includes a flange body 1 , a connecting cylinder positioning block 2 , and a flange circumferential positioning block 3 .

[0016] The flange body 1 is made of precipitation hardened stainless steel. The connecting cylinder positioning block 2 is two pieces, which are arranged on the bottom of the flange body 1 and ...

Abstract

The invention relates to a flange structure suitable for an underwater electromagnetic launch device and relates to the technical field of launch. According to the flange structure, special launch cylinder mounting holes and water replenishment holes are designed according to the seawater flowing direction and the motor movement direction, before an aircraft is launched, the interior of the launchdevice communicates with sea to achieve pressure equalizing of the interior of the launch device and seawater, the effect that thrust of a launch motor has nothing to do with the water depth is achieved, and large-depth and variable-depth launch is achieved. When the aircraft is launched, the seawater is replenished for a negative-pressure area formed after the motor moves at a high speed, and under the premise that the structural rigidity is met, the thrust loss of the motor is reduced. According to the scheme, the structure is simple, work is reliable, and mounting and fixing connectors areprovided for a launching cylinder.

Description

technical field [0001] The invention relates to the field of launch technology, in particular to a flange structure suitable for an underwater electromagnetic ejection device. Background technique [0002] In the underwater electromagnetic ejection device, the linear motor pushes the seawater into the launching tube, and uses the seawater to eject the aircraft out of the tube. During use, the linear motor needs to be completely immersed in seawater. The existing launching device flange completely isolates the external sea water from the space in the launching shaft, and cannot introduce the sea water outside the boat into the launching device. When launching, the mover moves at high speed, and a negative pressure area will be generated on the back of the mover, which increases the resistance of the mover. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to design a flange ...
