| Abstract: | In developing course the rocket engine of certain flight-assisted equipment＇s empennage wing pole whorl root part splits leads to the shell body fly not steadily occurs many times. Aiming at this problem, even temperature and stress field of this engine nozzle and the empennage wing pole package were thoroughly analyzed in this paper. Settlement method was given and the method was accepted. Verifying through follow-up many times flight, it was proved that counting analysis and the improvement design were effectively correctly |
