Abstract

Near space is an important airspace of the earth’s atmosphere. Detecting the characteristics of the atmospheric environment in the near space is the key to understanding the laws of atmospheric evolution. rocket dropsonde is an important means of sensing the pressure and temperature of near space in situ. and the data acquired by rocket dropsonde is influenced by the dynamic airflow. Herein a compensation method towards a kind of rocket dropsonde is presented and the feasibility is verified. A fluid-structure couple simulation towards the rocket dropsonde is run, and the results are discussed. The relationships between dynamic pressure, dynamic temperature, velocity and total pressure are come up with as the compensation for the rocket dropsonde.
