Abstract
A measure system is designed for aircraft cabin thermal comfort test, which can measure temperature, wind speed, humidity, pressure, flux, position parameters. The test results can be used to calibrate the model of temperature field simulation and cabin flow field simulation. The system synchronization accuracy is achieved 1mS. The measure system uses distributed configuration which comprises many measure cells. Test datum in the cabin can be set parameters and controlled re are transmitted to computer via internet. The measure equipment motely via internet, so that the measurement interfere affected by human activities can be reduced and the measurement accuracy can be improved. The measure system can communicate with instrument installation, making the cabin airflow field test automatism come true.
Highlights
With the development of civil aircraft design, in addition to meeting the safety and economic requirements for the design of civil aircraft, cabin comfort design is becoming more and more important
In addition to the multi-parameter synchronization test of each measuring point in the cabin, the test system can interact with the instrument installation platform to complete the automatic collection of cabin flow field data
The test system adopts a distributed architecture, that is, the test terminal is composed of multiple test units, placed near the test sensor nearby, and the data collected by the test unit is transmitted to the measurement and control room through Ethernet [5,6]
Summary
With the development of civil aircraft design, in addition to meeting the safety and economic requirements for the design of civil aircraft, cabin comfort design is becoming more and more important. One of the important controllable factors in comfort factors is thermal comfort, including chamber ventilation, wind speed, pressure, temperature, humidity, radiation, etc [14]. Through the high and low temperature environment simulation test system and the outside environment simulation facilities such as the sunshine simulation system, a close-to-real aircraft cabin environment is created to develop cabins thermal comfort test study. A large number of temperature, wind speed, humidity, pressure, flow, location, illumination and other parameters need to be tested. In addition to the multi-parameter synchronization test of each measuring point in the cabin, the test system can interact with the instrument installation platform to complete the automatic collection of cabin flow field data
