Description

technical field [0001] The invention belongs to the technical field of aircraft laboratory environmental field measurement, and in particular relates to an environmental field measurement device and method for an aircraft indoor blowing test. Background technique [0002] The large-scale comprehensive climate laboratory can simulate extreme low temperature, high temperature, blowing wind, humidity, snowfall, solar radiation, freezing rain, rain, freezing fog and other climate environments on the earth's surface, and its size can meet the blowing test of large equipment or complete machines need. When performing extreme low temperature or high temperature tests on large equipment or complete machines, it is necessary to monitor the environmental indicators around large equipment or complete machines in real time to ensure the safety and data collection tasks of large equipment or complete machines, so it must be arranged around them A temperature or humidity sensor at a cert...

AI Technical Summary

Problems solved by technology

During the blowing experiment, the measurement range of the temperature or humidity sensor is limited, resulting in inaccurate measured temperature and humidity values, and the temperature or humidity sensor is difficult to resist the interference of large airflow; the ambient temperature in the laboratory is generally -55 Temperature changes rapidly between ℃ and 70℃, so the design of the lifting rod structure needs to be able to meet the large changes in high and low temperature environments, and it is also necessary to ensure the installation and adjustment of various sensors and other measuring equipment under extreme environmental conditions to ensure real-time monitoring of data , the overall structure has safety, reliability and maintainability
