Problems solved by technology

[0003] In the existing technology, the method of manually moving and fixing the measurement rake is completely used for measurement. Due to the large number of measurement points and the large measurement range, it will take a lot of time. Especially for large-scale supercharged wind tunnels, under supercharged conditions, Every time one or a row of measurement points is replaced, the resident chamber needs to be inflated and deflated once

Embodiment Construction

[0026] Such as image 3 As shown, the two transmission support screws 2 are respectively fixed with the tooling frame through the chuck 4, as shown in Figure 4 As shown, the bottom of the tooling frame is provided with adjustable four anchor rods 5 . Such as figure 1 As shown, the measurement rake 3 is connected to the probe 1, which is the prior art. Measuring rake 3 is contained on the two transmission support lead screws 2, and can move up and down along the two transmission support lead screws. The upper and lower ends of the transmission support screw 2 are installed in the connection seat 9, such as Figure 5 As shown, the lower part of the coupling seat 9 is located in the base 11 and is mounted on the angular contact joint bearing 10 . Such as Figure 6 , Figure 7 As shown, a driving device is installed on the measuring rake, and the driving device includes a motor 12, a worm 13, and a worm nut 14. The worm 13 is driven by the motor 12, and the worm 13 drives t...

Abstract

The invention relates to a large tunnel traverse measuring device and an installing and debugging method thereof, for conveniently testing the flow field in a wind tunnel test and efficiently promoting the measuring efficiency. The technical solution is that a large tunnel traverse measuring device comprises a traverse measuring rake and a moveable assembling frame, wherein two driving support screws are respectively fixed with the assembling frame by a chuck, and the moveable assembling frame is installed on the driving support screw and can move up and down along the driving support screw.

Description

technical field [0001] The invention relates to a large-scale wind tunnel mobile measuring device and an installation and debugging method thereof. Background technique [0002] In the wind tunnel test of the aircraft simulation model, flow field calibration is required to measure the performance of the wind tunnel and the accuracy of the flow field quality, so as to check whether the indicators of the wind tunnel design are met. During flow field detection, it is necessary to measure the dynamic pressure field and direction field of a specified space point (wind tunnel flow field coordinate point) at a certain interval density on multiple sections of the wind tunnel test section. [0003] In the existing technology, the method of manually moving and fixing the measurement rake is completely used for measurement. Due to the large number of measurement points and the large measurement range, it will take a lot of time. Especially for large-scale supercharged wind tunnels, und...
