Wind tunnel research on statics thrust characteristics of vectoring nozzle

给出了轴对称收扩喷管和实施矢量偏转后的收扩喷管模型在FL 8风洞中的动力模拟静特性实验结果。对于轴对称喷管模型主要进行了喷管的推力特性测量,对于实施矢量偏转后的喷管模型除了给出了喷管推力特性外,还给出了喷管的偏转效率。实验结果表明:在FL 8风洞中进行单喷管的推力静特性测量实验结果可靠,与理论规律相一致。

The test results on statics characteristic of the models of axis symmetry convergentdivergent nozzle and nozzle having a vectoring angle are given in the paper. The experiment had been conducted in FL8 windtunnel. The thrust characteristics of axis symmetry nozzle were mainly measured in test. For the nozzle having a vectoring angle, the deflection efficiency was measured too. According to the test results, following conclusion can be drawn that the test results conform to theoretical laws and are dependable which required in FL8 windtunnel on statics thrust characteristics of single nozzle. 
