摘要:

升力体式浮升混合飞艇将艇体设计为具有较大升阻比的气动外形,升力由静浮力和气动力共同提供,适用于复杂地形下的大载重运输。控制速度和迎角的变化可有效控制动升力的大小,矢量推进系统的增加共同提高了飞艇的可控性,气垫着陆系统(ACLS)有效降低了地面保障系统的复杂度。多项系统的有效集成对总体设计提出较高的要求,通过重量平衡和推阻平衡的关系,对浮升混合飞艇进行了总体设计,分析了浮重比、巡航速度等参数对于总体性能的影响规律,同时研究了浮升飞艇气动性能、总体飞行性能和经济性能,为后续详细设计和有效控制方法的研究提供基础。

Abstract:

The liftbody-type buoyancy-lifting hybrid airships with high lift-drag ratio hulls can be used as heavy weight transportation under complicated geographic conditions. So the lift of hybrid airships, which is provided by static buoyancy and aerodynamic lift, can be changed by changing the velocity and angle of attack. The vector propulsion system can jointly enhance controllability of hybrid airships. The air-cushion landing system (ACLS) can effectively simplify the support system. An effective integration of these systems put forward higher requirements for the overall design. The general design of hybrid airships is illustrated by considering weight balance and thrust-drag balance. The analysis of the effects of parameters such as the ratio of buoyancy to weight and the cruise velocity etc. on the overall performance is made and the aerodynamic performance, the overall flight performance and the economic performance are studied at the same time. The conclusions are expected to lay a foundation for the research of detailed system design and effective control methods in the future.

Key words: hybrid airships, overall design, ratio of buoyancy to weight, aerodynamic analysis, vector propulsion
