| 总压探针结构是影响探针性能的关键因素，结构对总压系数、不敏感角大小等性能影响很大。为了研究总压探针性能的结构敏感性，制作不同类型且不同关键尺寸的总压探针，包括凸嘴型总压探针和带套型总压探针。在校准风洞上对这些探针进行总压系数校准试验，发现整流罩型探针性能最好，屏蔽罩型探针次之，凸嘴型探针性能最差。通过对比试验结果，得到了探针关键尺寸对其性能的影响规律。 |

| The structure of total pressure probe is the key factor affecting the probe performance. The structure greatly influences the total pressure coefficient and insensitive angle. In order to research the structural sensitivity of the performance of total pressure probe, different types of total pressure probes with different key dimensions are made, including convex-nosed total pressure probe and sleeve-type total pressure probe. The total pressure coefficient calibration test of these probes in calibration wind tunnel shows that the performance of rectifier-type probe is the best, shield-type probe takes the second place, and convex-nose type probe is the worst. By comparing the test results, the influence law of key dimensions of probe on its performance is obtained. |
