摘要
本文利用压强测量及纹影观测技术研究弹翼对旋成体底部流动及底阻的影响，研究对象包括有无收缩船尾的两种后体，井同时测量了模型的底面和侧面压强分布，通过实验观测结果和理论分析，得到较细致的弹翼干扰结果，有助于进一步认识底部流动特性及上游干扰，对飞行器设计有实用意义。
The effects of the wings on the revolution body base flow-field base drag were studied experimentally.The pressure measured and schlieren visualization techniques have been to obtain the results,which show that upstream influence and base flowfield properties.These results will be used in aircraft design and data correlation in wind tunnel test.
