Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting body type UAV capable of vertical takeoff and landing. The present invention is designed to take advantage of the advantages of a lifting body type aircraft in which a fuselage itself generates a lift force and the advantages of a flywheel aircraft capable of vertical takeoff and landing. Lifting body-type UAVs capable of vertical takeoff and landing include a body having aerodynamic characteristics in the form of a lifting body and a large main rotary fan for generating lift, at least one auxiliary rotary fan capable of providing attitude control and emergency auxiliary thrust , And a mission equipment mounting mechanism disposed near the center of gravity of the fuselage. In addition to the lifting body type UAV, the adjustment surface can be mounted on the tail or on the left or right side of the fuselage.

The lifting body type fuselage can be made into a triangle, a rectangle such as a square, a rectangle like a shield, a rhombus like a stingray, and a size and a shape are determined according to the mission and requirements. The unmanned airplane may add an adjustment surface for flight control during gliding, and this adjustment surface may be added in the form of a vertical surface on or below the fuselage, or in the form of an adjustment surface on the front or rear of the fuselage or the left and right adjustment surfaces.

The main body is equipped with a main rotation fan and auxiliary rotation fan for vertical takeoff and landing. The main rotation fan is mainly used for generation of lift, and the auxiliary rotation fan is used as an auxiliary thrust generator for turning, maintaining posture, rotation and emergency. The role of these main rotating fans and auxiliary rotating fans is similar to that of a generally known rotary wing unmanned aerial vehicle.

The lifting body-shaped fuselage can fly in the same shape as a long flight in the opposite direction of the airflow, maintaining a reasonably high angle of attack that maintains sufficient lift and stability, thereby drastically reducing fuel consumption . In order to make full use of these lifting body type characteristics, the main rotating fan and the auxiliary rotating fan are designed to be housed in the fuselage or to optimize the aerodynamic characteristics of the fuselage by blocking the air outlet of the bottom side fan based on the fuselage. Therefore, it is made of a curved surface of the fuselage to maintain the aerodynamic characteristics of the fuselage when not in use, and is smaller than the main rotary fan including the shutter device capable of opening and closing and the main rotary fan, And the main rotating fan and the auxiliary rotating fan may be installed inside the moving body, directly attached to the outside, or may be attached using a connection structure such as an arm.

Therefore, the UAV can maintain the proper angle of attack by using the surrounding air flow, thereby maintaining the lift and minimizing the operation of the fan, thereby minimizing the energy use and maintaining the same angle of attack, To maintain the posture. You can also close one or more of the fans' shutters and use less energy through glide flight using the aerodynamic characteristics of the lifting body type, shut off all the fans, and fly without gliding.

Also, folding auxiliary wings are accommodated in the fuselage, and folding wings can be folded and folded according to the necessary flight mode. The folding auxiliary wing is folded in such a manner that the folding wing is folded or folded. Further, a flexible solar panel may be mounted on the surface of the foldable auxiliary wing to secure auxiliary energy acquisition means.

The main rotating fan and the auxiliary rotating fan may be housed in a body, and the auxiliary rotating fan housed in the body may be housed according to the flight mode or may be configured to take out more than one. Auxiliary rotating fan is automatically turned on when some or all of the thrust is lost due to a malfunction in components other than the auxiliary rotating fan.

Although several embodiments of the present invention have been shown and described, those skilled in the art will readily appreciate that many modifications may be made without departing from the spirit or scope of the invention . The scope of the invention will be determined by the appended claims and their equivalents.
