摘要

针对长航时高空无人机探空需要

设计了一种0~16km高度的投弹式探空仪所搭载的温度传感器。利用计算流体力学(CFD)方法对探空仪外壳的外部多物理场分析

得到探空仪的温度传感器位置、风速后，再利用CFD计算海拔高度、风速、太阳辐射强度与太阳辐射误差之间的关系。随后

通过粒子群优化-反向传播(PSO-BP)算法训练数据并得到预测模型。最后

搭建低压风洞实验平台

展开对比实验，验证温度传感器的辐射误差。实验结果表明:长航时高空无人机平台所搭载的探空仪温度传感器测量误差平均绝对误差（MAE）为0.0123K

均方根误差（RMSE）为0.0171K。

Abstract

In view of the sounding needs of long-endurance highaltitude UAV

a temperature sensor carried by bomb-dropping sonde at an altitude of 0~16km is designed.The computational fluid dynamics(CFD)method is used to analyze external multiple physical fields of the sonde casing.After location and wind speed of the temperature sensor are obtained

CFD is further used to calculate the relationships among altitude

wind speed

solar radiation intensity and solar radiation error.Subsequently

the data are trained using the particle swarm optimization-back propagation(PSO-BP)algorithm and the predictive model is obtained.Finally

a low-pressure wind tunnel experimental platform is constructed to conduct comparative experiments to validate the radiation error of the temperature sensor.The experimental results show that the mean absolute error(MAE)of the temperature sensor for sonde carried on the long-endurance high-altitude UAV platform is 0.0123K

and the root mean square error(RMSE)is 0.0171K.
