Problems solved by technology

At present, there are more and more three-sonic wind tunnel tests. Manual operation not only wastes the test preparation time, but also requires special personnel to operate, which reduces the test efficiency and increases the test cost.
Therefore, it is necessary to design the inflatable sealing system into an automatic operation mode, which not only saves costs, but also improves the test efficiency. However, there is no automatic inflatable sealing system in the three-sonic wind tunnel at present.

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] see figure 1 , the embodiment of the present invention provides an automatic inflatable sealing system for a three-sonic wind tunnel, which is used for sealing the internal movement or replacement parts of the three-sonic wind tunnel. The sealing ring is inflated to achieve sealing. After the test is completed, the gas inside the sealing ring needs to be exhausted to separate the two parts for replacement. Among them, the three-sonic wind tunnel includes: transition section, test section, super expansion section, super expansion section Section regulating piece and telescopic section, this self-inflating seal comprises: intake pipeline, first inflation shunt, second inflation shunt, gas collecting pipe, deflation pipeline and control device.

[0019] Among them, the air intake pipeline is used to transport the gas used for sea...

Abstract

The invention discloses an automatic inflation sealing system used for a trisonic wind tunnel. The system comprises an air inlet pipe, a first inflation branch, a second inflation branch, a gas collecting pipe, a deflation pipe, and a control device. The trisonic wind tunnel comprises a transition segment, a test segment, an over-expending segment, an over-expending segment adjusting sheet, and a flexible segment. The system can automatically operate according to process flow of inflation and deflation, saving inflation and deflation time of the inflation sealing system, improving wind tunnel test efficiency, and operation accuracy is greatly improved.

Description

technical field [0001] The invention relates to an inflatable sealing system, in particular to an automatic inflatable sealing system for moving or replacing parts inside a three-sonic wind tunnel. Background technique [0002] Inside the three-sonic wind tunnel, there are many parts that need to be moved or replaced, such as the test section, solid-wall nozzle and super-expansion section, etc. The wind tunnel needs to be opened during the test preparation stage, and these parts need to be moved or replaced. The number of tests is large, in order to reduce the moving or replacement time and improve the test efficiency, therefore, the air-filled sealing system is often used in the wind tunnel. The traditional method adopts manual inflation and deflation operations, that is, at the beginning of the test, the manual valve switch operation is performed manually on site to realize inflation, and after the test is completed, the manual valve is manually operated to realize deflati...
