Description

Technical Field

[0002] Wind tunnel tests are an important means for aerodynamic research, with irreplaceable advantages. Precise control and measurement of wind tunnel air flow parameters (velocity, pressure, temperature) play an important role in ensuring the accuracy and reliability of test results. According to Bernoulli's equation, after measuring the total pressure and static pressure of the wind tunnel air flow, the velocity pressure of the air flow can be obtained, and then the air flow velocity can be obtained.

[0003] The velocity pressure measurement system of a low-speed wind tunnel mainly consists of a wind speed tube and a pressure acquisition system. The total pressure measurement hole is located at the vertex of the windward arc surface of the wind speed tube, and the static pressure measurement hole is located on the wall surface of the arc circumference of the wind speed tube. The traditional detection and calibration method is to first disconnect the hoses connecting the wind speed tube to the total and static pressure measurement holes, and then separately detect the wind speed tube and the pressure acquisition system. This method has many problems such as the need to disassemble the wind speed measurement system, many links, large workload, and the inability to quantify the airtightness detection.

[0009] Furthermore, a rapid detection and calibration method for a wind tunnel dynamic pressure measurement system is realized by using a rapid detection and calibration device for a wind tunnel dynamic pressure measurement system;

[0010] When detecting the total pressure of the wind speed tube, the following steps are included:

[0011] Step 1: Insert the wind speed tube into the detection sleeve, and lock and seal the left end of the detection sleeve through a sealing plug, a first perforated fastening nut, a first sealing ring, and a first pair of wires; lock the positive and negative tensioning nuts, and lock and seal the total pressure sealed cavity through a third pair of wires and a third sealing ring;

[0013] Step 3: Connect an external high-precision standard pressure source, start the dynamic pressure acquisition system for data acquisition and calculation, and complete the rapid detection of the dynamic pressure acquisition system pipeline and the calibration and calibration of the dynamic pressure acquisition system;

[0014] When detecting the static pressure of the wind speed tube, the following steps are included:

[0015] Step A: Insert the wind speed tube into the detection sleeve, lock the positive and negative tensioning nuts, and complete the sealing of the static pressure sealed cavity in the detection sleeve through the third sealing ring and the third pair of wires at the left end of the static pressure sealed cavity; lock and seal the right end of the static pressure sealed cavity in the detection sleeve through a second sealing ring, a second perforated fastening nut, and a second pair of wires;

[0024] Working principle:

[0025] The present invention installs a dedicated sealing device on the wind speed tube of a low-speed wind tunnel, which can directly apply standard pressure to the total pressure measurement holes and static pressure measurement holes on the surface of the wind speed tube at the same time. The device includes a sealing plug, a perforated fastening nut, a sealing ring, a pair of screws, a digital pressure gauge, a pointer pressure gauge, positive and negative tension nuts, a detection sleeve, a wind speed tube, a gas path connector, a gas path valve, a dedicated hose, a standard pressure gauge, and a dynamic pressure acquisition system. The device has strong sealing performance and can be quickly installed on the wind speed tube of a low-speed wind tunnel. The standard pressure gauge directly applies standard pressure to the total pressure measurement hole and static pressure measurement hole of the wind speed tube respectively. The digital pressure gauge and pointer pressure gauge connected to the detection sleeve of the wind speed tube will quickly display whether there is a change in the applied standard pressure. At the same time, through data acquisition and calculation of the acquisition system, the detection and calibration of the dynamic pressure measurement system of the low-speed wind tunnel can be quickly completed, including the airtightness detection of the wind speed tube and the calibration of the pressure acquisition system.

[0026] The present application has the following beneficial effects:

[0027] 1. By installing a sealing plug and tightening the perforated fastening nut in the present invention, the sealing of the total pressure hole cavity of the sleeve is completed through the sealing ring and wire drawing; by tightening the positive and negative tension nuts, the sealing of the static pressure hole cavity of the sleeve is completed through the sealing ring and wire drawing; a pointer pressure gauge and a digital pressure gauge are simultaneously connected to the detection sleeve of the wind speed tube. The two pressure gauges can perform mutual detection and supervision functions, making the rapid detection results of the wind speed measurement system of the low-speed wind tunnel more accurate and reliable. The detection parameters of the wind speed measurement system include: total pressure value, total pressure pipeline leakage, static pressure value, static pressure pipeline leakage, dynamic pressure (total static pressure difference) value, and the change of dynamic pressure.

[0028] 2. By separately applying standard pressure to the total and static pressure measurement holes of the wind speed tube in the present invention, the airtightness detection of the pipeline of the dynamic pressure measurement system and the calibration of the overall acquisition system can be completed simultaneously.

[0029] 3. The present invention can improve the detection efficiency of the dynamic pressure measurement system of the low-speed wind tunnel and the accuracy of the air flow velocity measurement results, and can improve the test efficiency and reduce the test cost for production-type low-speed wind tunnels.

[0030] Comparison of detection efficiency:

[0031] Conventional method (before the invention of this device and method): During the test process, since the total and static pressure holes cannot be sealed without the aid of equipment, the pipeline can only be disassembled and detected section by section, and the overall pipeline sealing detection work cannot be completed. After the test, the pipeline needs to be restored, and this process takes 90 minutes.

[0032] Current method (using this device and method): According to the invention content and usage steps, after sealing the total static pressure holes of the anemometer tube, the total static pressure pipelines of the anemometer tube can be pressurized separately. Based on the pressure holding situation, it can be judged whether there is a problem with the entire gas path. This process only takes 15 minutes, greatly improving the pipeline detection efficiency.

[0033] Accuracy comparison:

[0034] Conventional practice (before the invention of this device and method): During the test, doubts arose about the anemometer tube data. Since the total static pressure holes could not be sealed, it was impossible to maintain the standard pressure applied to the measurement pipeline, and the air leakage situation could not be quantified.

[0035] Current method (using this device and method): According to the invention content and usage steps, after sealing the total static pressure holes of the anemometer tube, the total static pressure pipelines of the anemometer tube can be pressurized separately. According to the indication of the pressure gauge data, the situation of the total static pressure pipeline of the anemometer tube can be directly detected, and the pipeline leakage amount can be quantified. The leakage amount can be accurate to within 10 Pa. Description of the drawings
