Problems solved by technology

[0003] The pressure measuring rake and the pipe rack are generally fixed to the cave wall by bolts, and it is necessary to open a fixing hole on the cave wall for connecting the pressure measuring rake and the pipe rack, which will inevitably cause damage to the cave wall; and the machine in the wind tunnel Positions such as the glass bottom plate and close to structural beams are not conducive to the opening of fixing holes
[0004] However, the moving frame needs to be installed with slide rails, and the relative fixed position of the sliding rails and the moving frame needs to be ensured. It may also need a drive and control system, which requires high installation requirements and a complex system.

Abstract

The invention relates to the field of wind tunnel test flow field calibration and measurement, in particular to a hanging frame for a wind tunnel test, wherein a probe is fixed at a test section in the wind tunnel test. The hanging frame comprises a hanging frame mechanism, a first brake pad and a second brake pad, wherein a fixing hole is formed in the hanging frame mechanism, one end of the hanging frame mechanism is connected with the first brake pad, and the other end of the hanging frame mechanism is connected with the second brake pad through a telescopic mechanism. The hanging frame isconvenient in installation, the installation position range is larger, and the arrangement of installation holes in the wall surface of a wind tunnel is avoided.

Description

technical field [0001] The invention relates to the field of wind tunnel test flow field calibration and measurement, in particular to a hanger for wind tunnel tests in which a probe is fixed in a test section in the wind tunnel test. Background technique [0002] According to the national military standards, the low-speed wind tunnel flow field calibration and measurement items mainly include dynamic pressure, direction field, axial static pressure gradient, airflow temperature, turbulence degree, etc. At present, the parameters of different positions in the wind tunnel test section are mainly measured by probes. It is inevitable to fix the probe at many different measuring points. Usually, the devices for fixing the probe include pressure measuring rake, pipe rack, moving measuring frame and other devices. [0003] The pressure measuring rake and the pipe rack are generally fixed to the cave wall by bolts, and it is necessary to open a fixing hole on the cave wall for co...
