Pneumatic layout of dual flying wings of UAV (Unmanned Aerial Vehicle)

Abstract

The invention relates to a pneumatic layout of dual flying wings of a UAV (Unmanned Aerial Vehicle). The pneumatic layout is characterized by comprising a pneumatic layout of a blended wing body flying wing, a layout of installing a turbofan engine above the rear section of the blended wing body flying wing and a pneumatic layout of installing a stabilator at two sides of a nacelle on the outer wall of the turbofan engine, wherein the blended wing body flying wing with a high lift-to-drag ratio is formed by a fuselage, wings, wingtip winglets and direction ailerons together; the stabilator which is used for providing a positive lifting force during flight trimming of the UAV is formed by horizontal tails and horizontal tail winglets, and the dual flying wings are formed by the blended wing body flying wing and the stabilator together. According to the pneumatic layout of the dual flying wings of the UAV, disclosed by the invention, the UAV has high lift-to-drag ratio, good operability and high stability, and the pneumatic layout has the advantage of good stealth performance.

Description

technical field [0001] The invention relates to an aerodynamic layout of double flying wings of an unmanned aerial vehicle, belonging to the field of aviation technology. Background technique [0002] At present, the flying wing layout is a layout form widely used in advanced aircraft, and it is one of the hot issues in the research of aircraft aerodynamic layout in recent years. Flying wings are famous for their high lift-to-drag ratio and good stealth performance among the large aircraft families in the world today. The representative of Flying Wing is the X-47B experimental carrier-based UAV of the United States. This type of UAV successfully made its first flight on February 4, 2011, and successfully completed a series of ground and ship surface tests in 2013. However, the shortcomings of the flying wing layout are also obvious, mainly in poor control performance and poor stability, and it needs to completely rely on electronic sensors to control the rudder surfaces of ...
