The air guide mechanical structure of the fuselage transport vehicle in the aircraft

Abstract

The invention relates to an air flow guide mechanical structure of a middle fuselage of an aircraft. The air flow guide mechanical structure comprises a front flow guide device and a middle flow guide device, wherein the front flow guide device is arranged on a gooseneck, the middle flow guide device is arranged on a middle vehicle frame, the front flow guide device comprises a flow guide cover, a pin shaft and a telescopic connecting rod, and the middle flow guide device comprises a turnover square wheel, a turnover hydraulic cylinder, an extensible hydraulic cylinder and an extensible protecting plate. The air flow guide mechanical structure has the advantages that the air dynamics characteristic of surrounding air fields in the long-distance high speed transportation process of the transportation vehicle body is changed, the action force of the air drag on the middle fuselage is effectively reduced, the function of air drag on the middle fuselage is reduced, the stress deformation of the middle fuselage is prevented, the drag of the transport vehicle in the driving process is reduced, and the tilting of the transport vehicle caused by overlarge air drag is prevented.

Description

technical field [0001] The invention relates to an air guide mechanical structure of a fuselage transport vehicle in an aircraft. In the field of aerodynamics. Background technique [0002] During the high-speed driving process of the aircraft mid-fuselage transport vehicle, because the overall height of the mid-fuselage is high after loading, and it may encounter severe weather such as strong winds during long-distance transportation, the running direction of the vehicle is affected by the wind field around the vehicle during transportation. The wind resistance and side load are very large, which may cause impact on the middle fuselage, causing the middle fuselage to be deformed by force, and also pose a certain threat to the driving safety of the transport vehicle. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of air diversion mechanical structure of aircraft middle fuselage transport veh...
