Abstract

The invention relates to a small UAV aerodynamic layout for vertical rope-type recovery on a moving base within a small spatial scope, which comprises a UAV body, wings and an engine tail wing; the wings are upper single wings, and the installation angle is 3 degrees; an engine is arranged at the tail of the UAV body; the layout is characterized in that the aspect ratio of the wings is 9, a sweepback method is adopted, and a sweepback angle is 23 degrees; the lower surface of the middle part of the left wing or the right wing is provided with a horizontal strut for installing the tail wing; the rear end of the horizontal strut is provided with a horizontal tail wing and a vertical tail which is arranged in an inverted way, and the vertical tail is inclined inwards for 15 degrees. Compared with the prior art, the small UAV aerodynamic layout for vertical rope-type recovery has the advantages of reducing the number of operators, and improving the effective load capacity and the wind resistant capability of an airplane.

Description

Technical field

[0001] The invention relates to the aerodynamic layout of a small unmanned aerial vehicle used for vertical rope recovery, and belongs to the field of aircraft aerodynamic layout design. It is especially suitable for popularization and use on moving bases within a narrow space.

[0002] The present invention is an unmanned aerial vehicle aerodynamic layout with a medium aspect ratio, a swept-back wing and a separate inverted V tail with double tail braces that can be efficiently and non-destructively recovered within a narrow space on all terrains. Background technique

[0003] As far back as the 1960s, there was a desire to use drones on mobile pedestals in tight spaces, but it was no easy feat.

[0004] First of all, the take-off and landing tasks of UAVs used on moving bases are much more difficult and dangerous than manned aircraft, requiring close cooperation between well-trained dispatchers and maintenance operators, increasing the configuration of ope...
