In the vertical take-off and landing unmanned drone, one or more vanes folded in a folded state or folded in the body may be included.

In the vertical take-off and landing unmanned drone, one or more folding wings may be geometrically connected to act as a single wing.

In the vertical take-off and landing unmanned drone, the foldable wing may be partially folded or folded in bad weather conditions to maintain stability.

In the vertical take-off and landing unmanned drone, the drag force may be reduced by adjusting the wing area when a high-speed flight is required.

In the vertical take-off and landing unmanned drone, it is possible to make a control scenario through experiment and experience so as to maintain the optimum gas direction and the angle of attack according to the direction and speed of the airflow, and thereby maintain the posture automatically.

In the vertical take-off and landing unmanned drones, the yaw, pitch, and roll attitude fluctuations of the UAV are estimated to estimate the current airflow state, and the flight path is calculated again in accordance with the automatically set optimal attitude , It may be automatically adopted or used at the option of the operator, and may be instructed to manipulate the orientation of the mounting equipment accordingly.

An example of a vertical take-off and landing unmanned aerial vehicle according to one embodiment of the present invention is shown in FIG. 1, and the present invention will be described with reference to FIG.

The present invention deals with a method for extending the running time of an unmanned aerial vehicle that takes off and land vertically using a device such as a fan. In this method, an unmanned aerial vehicle is used that takes off and land vertically using one or more vertical fans and generates horizontal propulsive force using one or more horizontal prop rods.

In particular, the unmanned aerial vehicle can be vertically or horizontally folded or fixed with one or more wings that can be housed in an airframe capable of aerodynamically generating lift, or folded to the outside, a wing front or rear, Includes an adjustment surface on both sides.

The wings may be of a flexible material or of an inflexible form having a foldable structure.

At take-off and landing, one or more vertical fans, either alone or in combination, lift up to a certain height and then spread the folded wing, generate a lift by operating a horizontal propulsion prop, stop the vertical fan, And it keeps its posture automatically by using the fuselage, the wing, and the adjustment surface installed on the vertical wing, cruises the flight path of a certain circular or elliptical shape, a combination of a straight line and a circle, manipulates the mount of the mounting equipment And a method of orienting only one direction and controlling the posture such as the direction of the gas and the attitude angle according to the direction of the airflow to minimize fuel consumption.

When bad weather or fast speed is needed, the wing may be folded as needed to control the drag. For the long-term flight, the control scenarios are created through experiment and experience so as to maintain the optimum gas direction and the angle of attack according to the direction and speed of the airflow. In order to maintain the posture automatically, Pitch, Roll The posture can be controlled by estimating the current airflow state by measuring the posture change.
