| 摘 要： | 为了保证某型反潜直升机的投雷安全，需要了解直升机腹部的流场在各个方向上的特性。在对几种典型的流场测量技术和方法进行比较之后，利用七孔探针测量系统在复杂流场环境下的测量优势，对直升机的腹部流场进行测量，得到了腹部弹舱以下3个不同高度的测点、在不同飞行状态下的速度矢量。通过对测量所得数据的分析，得到了机腹流场的基本变化规律，以及其对该型直升机投雷的影响。结果表明：直升机的腹部流场不会影响到投雷安全。同时结合对流场产生及变化的理论分析，也验证了实验的可靠性。

| Abstract: | In order to ensure the safety of the anti-submarine warfare (ASW) helicopter in dropping torpedo,it is necessary to understand the flow field characteristics in each direction and its effect to the torpedo dropping. Some representative flow measurement technology and methods are compared. By means of the seven-hole probe measurement in complicated condition,the velocities of the flow field are obtained at three different heights and different flying states. Through data analysis,the basic laws of the flow f... |
