Embodiment 1

[0023] Embodiment 1. When the rocket engine is started, the UAV obtains the maximum thrust and takes off directly from the launch pad, relying on the wings to provide lift, and the rudder surfaces of the wings and tails provide flight control capabilities to achieve high-speed cruise and long-distance delivery.

Embodiment 2

[0024] In the second embodiment, when each ducted fan is activated, eight fans are used to provide lift, and the thrust of different fans can be changed through the flight control to realize low-speed short-distance maneuvering.

[0025] Working process of the present invention:

[0026] The invention is a variable-configuration unmanned aerial vehicle. The take-off state is a fixed-wing configuration. After receiving the take-off command, the rocket engine is started, and the unmanned aerial vehicle takes off from the ejection frame and flies to the designated area. At this time, the wings provide lift. The ailerons of the aircraft provide lateral maneuverability, and the V-shaped tail rudder surface on the empennage provides longitudinal maneuverability and heading maneuverability. After approaching the designated area, the rocket engine is turned off, the drogue parachute on the multi-duct fuselage is opened, and the aircraft slows down to fly. Detach from the multi-ducted...

Abstract

The invention relates to a variable configuration unmanned aerial vehicle, which has two configuration modes of fixed wing and multi-duct. The unmanned aerial vehicle of the invention uses the fixed wing configuration to realize long-distance delivery and high-speed cruise functions. After arriving at the target area, use the multi-duct configuration to carry the designated mission system, and rely on hovering and precise maneuvering capabilities to perform tasks. The ability of man-machine to perform tasks in a specific area.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a variable configuration unmanned aerial vehicle.
