Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as figure 1 , 2 As shown, the present invention provides a channel structure for an airship, which includes a control rod 1 and several deflectors 2 that can be rotated by the control rod 1. The several guide vanes 2 are arrayed obliquely from bottom to top. The present invention can be hung below the airship, the deflector is connected by a control rod, and the inclination angle can be changed within the range of 0 to 90 degrees, and the control rod is controlled by the steering gear 4 .

[0028] The section of the guide vane 2 is arc-shaped; the radian of the guide vane 2 is 30-90°; the angle θ between the direction of the oblique array of the guide vanes 2 and the horizontal plane is is 20 to 90°; the relationship between the arc radius r of the deflector 2, the height h of the channel and the number n of the deflector 2 is:

Abstract

The invention relates to a duct structure for an airship, the structure comprises a control lever and a plurality of guide vanes which can rotate through the control lever, the control lever and a plurality of the guide vanes are connected in transmission, and a plurality of the guide vanes are arrayed in an inclined way from bottom to top. Compared with the prior art, by adopting the structure, a single motor is only needed, the motor is fixedly arranged in the duct, and a reversing vane in the latter part of the duct is used to change the direction of a propelling force, thus realizing the functions of ultra-short takeoff and landing and hovering in the air; and compared with a bi-motor by-pass rotation technology, the scheme has simple manufacture and low cost, can realize main functions and is suitable for a small-sized unmanned airship.

Description

technical field [0001] The invention relates to an airship, in particular to a channel structure for an airship. Background technique [0002] Airship (Airship) is a kind of aircraft with air buoyancy air, its flight lift mainly comes from the air buoyancy acting on the fuselage, and has a control and propulsion system. Usually its propulsion system consists of a propeller system driven by an aeroengine. Since the birth of airships, airships have been widely used in war and civil photography, and weather forecasting. [0003] The flying principle of the airship is to make the self-weight G of the airship slightly greater than the buoyancy V1 produced by the hull airbag. When the propeller starts to rotate, the airship generates a forward speed and makes the hull airbag have a certain elevation angle to generate part of the lift V2. The airship can The buoyancy V for liftoff comes from two parts: [0004] V=V 1 +V 2 >G [0005] Therefore, the airship must maintain a ...
