Embodiment Construction

[0045] This embodiment is a stratospheric airship with a double-row wing layout. In the atmospheric environment at different altitudes, the change of the wing span of the entire airship can be realized through the telescopic transformation of the telescopic rod, thereby realizing the controllable buoyancy. .

[0046] This embodiment includes an ellipsoidal cabin body 1, a propeller propulsion device 2, a double-row wing 3, a flat tail 4, a vertical tail 5, a telescopic rod 6, a supporting rib 7, a capsule membrane structure 8, a hydraulic hole 9, and a spring 10 and control system. in:

[0047] The cabins are divided into three, namely a central cabin 11 and two wingtip cabins 12, wherein there is a payload pod at the bottom of the central cabin. In the present embodiment, the lengths of the major axis and the minor axis of the ellipsoidal central cabin are 2.30C and 0.70C respectively, and the lengths of the major axis and the minor axis of the wingtip cabin are 1.80C and 0...

Abstract

The invention discloses a wingspan-changeable inflatable floating and rising integrated stratospheric airship. The wingspan-changeable inflatable floating and rising integrated stratospheric airship comprises a central cabin and two wingtip cabins. Four propeller propelling devices are mounted on the central cabin, and two propeller propelling devices are mounted on each wingtip cabin. Double-row wings are adopted, and the interior of a front wing body and the interior of a rear wing body of each wing are both provided with three air chambers distributed in the extension direction. All the air chambers are separated from one another through supporting ribs. The inner surfaces of all the wing bodies adhere to the outer profiles of the supporting ribs. Telescopic rod sets are arranged in the air chambers respectively, the diameters of telescopic rods of the telescopic rod sets in the air chambers are different, and thus the telescopic rods in the air chambers can stretch and retract in a nested mode. The wingspan-changeable inflatable floating and rising integrated stratospheric airship has the advantages that the aerodynamic efficiency is high, and generated dynamic lifting force is large; both control and manipulation are quite convenient, and adjustment of different air-staying heights is achieved by adjusting the extension lengths of the wings.

Description

technical field [0001] The invention relates to the design field of modern near-space aircraft, in particular to a new-concept stratospheric airship with low speed, variable wingspan and integrated buoyancy and lift. Background technique [0002] In recent years, driven by the needs of sub-regional high-resolution long-term real-time monitoring, early warning, missile defense, atmospheric environment monitoring, noise control and environmental protection requirements, stratospheric airships have become high-level military and civilian information platforms that are of great concern at home and abroad. . [0003] The lift of a traditional airship depends entirely on its own static buoyancy. Since this type of aerostat does not need dynamic lift to fly in the air, it is very suitable for staying at high altitudes for a long time to perform tasks. However, due to the thin air at high altitudes, airships relying solely on static lift are huge in size, and the huge size will exc...
