直升机着水载荷试验研究

为进一步提升中国国内直升机缩比模型着水试验能力,为中国民用直升机水上迫降适航取证提供技术支撑,本文对国内直升机缩比模型着水试验及试验结果进行了研究。通过介绍模型着水试验的试验设备、试验件、试验要求和试验步骤,并对着水载荷结果与俄罗斯中央空气流体动力研究院莫斯科学院的试验结果进行对比分析,验证了中国直升机缩比模型着水试验能力,为中国进行直升机水上迫降方面的模型着水试验提供了技术参考。

Test Research on Helicopter Ditching Load

To further develop the ability of helicopter scaled-model ditching test and support the civil helicopter airworthiness in China, the ditching test on helicopter scaled-model is carried out. The equipment, the scaled model, test requirements and the process are introduced. The test results are compared with that of Moscow Branchof TsAGIof Russia to certify the ability of helicopter scaled-model ditching test in China. The paper supplies technical reference for the ditching test in China.
