    摘要:

    高升阻比设计是浮升一体化飞艇研制中亟待解决的关键难题,艇身是决定全艇升阻比高低的关键部件。针对飞艇高升阻比布局设计的难度及复杂约束性要求,有效结合艇身精细化气动设计、流动控制和升力体理念,引入高精度气动数值模拟等多种手段,探讨构建中央翼+边条耦合、中央翼+端板融合等多种艇身新布局形式,揭示关键几何参数表征与高升阻比特性的影响关系,获得具有高升阻比特征的浮升一体化飞艇艇身新型布局形式。结果表明:与传统混合飞艇艇身构型相比,在保证艇身体积不变和艇身宽度适当控制的前提条件下,中央翼+边条增升耦合艇身构型可提高最大升阻比约77% 以上;中央翼+端板式融合艇身构型可实现最大升阻比值由2.13 提高到3.95 以上,至少提高了85.4%。

    Abstract:

    High lift-to-drag ratio design is has become a urgent key problem to be solved, and the hull is the decisive part to the lift-to-drag ratio of the whole airship. Pointing at the difficulty of the high lift-to-drag ratio airship configuration design and complicate constrained requirements, effectively combined with airship hull fine design, flow control technology and lifting body concept, using high precision aerodynamic numerical simulation method, explore and build several new airship hull configuration types, such as airship hull with lift-enhanced strake and center airfoil body hull with end-plates, research on the influence of key geometric parameters on the high lift-to-drag ratio features, get a few new buoyancy-lifting airship hull with high lift-to-drag ratio. The research shows, compare to the original airship hull, with the constraint of volume, adjusting the width of the hull properly, the maximum lift-drag ratio of the airship hull with lift-enhanced strake is 77% larger , the maximum lift-drag ratio of the center airfoil body hull with end-plates is 3.95, in contrast to the original airship hull’s maximum lift-drag ratio which is 2.13, the promotion amount is at least 85.4%, related achievements can provide technical solution and reference to future new conceptual heavy load buoyancy-lifting airship design of our country.
