平流层飞艇热力学验证温度测量方法研究

Research of Stratospheric Airship Temperature Measurement for Thermodynamics Demonstration

平流层飞艇的热力学分析是平流层飞艇关键技术之一。针对热力学分析的工程验证及模型完善,提出了适合于平流层飞艇的艇囊内气体及囊体表面的温度测量方法,包括采集点的分布,传感器的选型,数据传输和处理及数据准确性评价等。经过两次平流层飞艇的缩比飞行试验,对比同艇发放的探空仪采集的温度数据,验证了该方法测量到的数据的准确性。

The, analysis of the stratospheric airship＇ s thermodynamics model is an important techni- cal direction of the research of the key technologies of the stratospheric airship. According to the engi- neering verification and improvement of thermodynamic model, the suitable method for stratospheric air- ship＇s inside air temperature measurement, including the distribution of the sensor, sensor selection, data transmission and processing, etc is put forward . After two flight test, contrast with temperature data of the boat by the dropsonde which was bind on the hull of the airship , this method verified the accuracy of the data of air temperature.
