Title:
BARREL-LAUNCHED FOLDING-WING UNMANNED AERIAL VEHICLE AND LAUNCH METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/133089
Kind Code:
A1
Abstract:
A barrel-launched folding-wing unmanned aerial vehicle and a launch method therefor. The barrel-launched folding-wing unmanned aerial vehicle comprises: a folding-wing unmanned aerial vehicle (7) and a launch barrel (6). When in a barrel-packed state, the folding-wing unmanned aerial vehicle (7) is in a fully folded state and provided within the launch barrel (6). When the launch barrel (6) launches the folding-wing unmanned aerial vehicle (7), the folding-wing unmanned aerial vehicle (7) is ejected from the launch barrel (6), undergoes a transformation process of gradual unfolding, and then climbs to enter a fully unfolded cruise mission state. The folding-wing unmanned aerial vehicle (7) comprises a fuselage (1), Z-shaped folding springing wings (2), a left fully-movable horizontal stabilizer (3A), a right fully-movable horizontal stabilizer (3B), a fully-movable vertical stabilizer (4), and a foldable propeller component (5). The unmanned aerial vehicle, by using the Z-shaped folding springing wings having the characteristics of a small footprint in a folded state and a large wing area and a large aspect ratio in an unfolded state, effectively increases the space utilization rate of the unmanned aerial vehicle and the aerodynamic performance thereof in the cruise mission state.
