Abstract:

Kunpeng-1B sounding rocket was launched successfully by the National Space Science Center of Chinese Academy of Sciences at Danzhou, Hainan on April 27, 2016. The attitude of the payload service system fell into nutation mode after being separated from the launching vehicle, which is beyond the designing limits. In this paper the possible factors triggering the nutation movement are analyzed, the attitude dynamics equations of the payload service system are set up, and the nutation movement is reproduced by numerical simulation. By comparing the simulating nutating results with the real flying nutation, the main elements triggering the nutation are obtained. The results can provide reference for the follow-up sounding rocket designing.

Key words: Sounding rocket, Nutation movement, Numerical simulation
