摘　　要：在完成了某型飞机模型自由飞失速／尾旋特性试验研究的基础上，改变飞机局部构形，加装腹鳍和翼刀，进行其失速／尾旋特性探索性试验。着重介绍试验的情况以及几种改变的不同组合对尾旋模态的影响，为设计部门更改设计提供了依据。On the base of completed the model free flight test research for an aircraft'sstall/spin characteristics, test is going on by changing the parts of aerodynamic appearance ofaircraft through in stalling up ventral fins and wing fences,it can help us to have a betterinvestgation of the aircraft's spin.The focal point of this paper is introduction of testcircumstance,and it mainly researches the influences of some changing constitutes for spincharacteristics,this can provide reliance in the variation of design for design department.
