摘要 倾转旋翼飞机同时具备低速垂直起降和高速巡航飞行的能力,受到航空从业者高度重视;而短距起飞相比于垂直起飞可以提升有效载荷以及起降安全性,是倾转旋翼飞机特有的起飞方式之一。面向方案设计阶段,研究倾转旋翼飞机在短距起飞模式下,推导该类飞机地面滑跑距离与短舱动力倾转角、推重比等设计参数之间简洁有效的理论公式;并予以计算分析。结果表明:该方法合理可信,所得结论可为同类飞机设计提供参考,具有良好的工程应用价值。 Tilt-rotor aircraft has capability of both vertical take-off in low-speed and cruise in high-speed,and therefore has been highly valued by aviation practitioner. Short take-off performance can increase more payload and get higher safety than vertical take-off,so it is one of the unique take-off methods for tilt-rotor aircraft. The concise and effective formula were deduced for distance of takeoff run between tilting angle of engine nacelles and thrust to weight ratio for tilt-rotor aircraft in the short take-off mode during conceptual design stage and finally the work of calculation and analysis was done to validate the formula. The result shows that the method is reasonable and credible,the conclusion can be generally applied to similar aircraft and has good engineering application value.
