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.
