The invention provides an unmanned helicopter hovering state snow blind test device and method based on a fixed platform, and belongs to the field of helicopter flight tests. The invention aims to solve the problem of blank of related research in the technical fields of helicopter snow field flight and snow blindness in China. The method comprises the following steps: S1, selecting a test environment and a test site meeting test conditions; s2, determining a test working condition; s3, test equipment is installed on the test site; s4, arranging a wind-shield wall outside the test field; s5, measuring physical characteristics of accumulated snow on the test site; s6, carrying out a test according to the determined test working condition; s7, ending the test; s8, measuring physical characteristics of accumulated snow in the test site after the test; s9, measuring the physical characteristics of the collected snow particles; s10, arranging the equipment; and S11, analyzing the recorded test data. According to the invention, the influence characteristics of the helicopter in snowfield flight and snowblindness can be deeply researched, and the blank of related research in the technical field of helicopter snowfield flight and snowblindness in China is filled.

    本发明提出一种基于固定平台的无人直升机悬停状态雪盲试验装置及方法,属于直升机飞行试验领域。目的是解决现有国内在直升机雪域飞行和雪盲技术领域相关研究空白问题。本发明包括以下步骤:S1选择满足试验条件的试验环境和试验场地;S2确定试验工况;S3在试验场地安装试验设备;S4在试验场场地外设置挡风墙;S5测量试验场地积雪物理特性;S6根据确定的试验工况开展试验;S7试验结束;S8试验后测量试验场地积雪物理特性;S9对收集雪粒的物理特性进行测量;S10设备整理;S11分析所记录的试验数据。通过本发明,可以深入研究直升机在雪域飞行及雪盲现象的影响特性,填补国内在直升机雪域飞行和雪盲技术领域相关研究的空白。
