Flying wing layout unmanned aerial vehicle wing multi-configuration coordination design method

Abstract

The invention relates to the field of unmanned aerial vehicle design, in particular to a flying wing layout unmanned aerial vehicle wing multi-configuration coordination design method which comprises the steps of 1, wing size parameter coordination design; 2, wing plane parameter coordination design; 3, carrying out coordinated design on wing profile parameters; 4, carrying out coordinated design on the airfoil profile; 5, coordinating and designing a high-aspect-ratio wing matched with the small-and-medium-aspect-ratio flying wing layout unmanned aerial vehicle platform; and for each group of shapes, screening out a scheme with the maximum cruise lift-drag ratio and the minimum head lowering torque as a final high aspect ratio wing scheme through simulation. The design method is simple and good in practicability, repeated iteration of scheme design is avoided, meanwhile, the key problem, namely the pneumatic design problem, of multi-configuration wing design of the flying wing layout unmanned aerial vehicle is solved, the wing configuration changing technology of the flying wing layout unmanned aerial vehicle is further promoted, and high engineering application value is achieved.

Description

technical field [0001] The invention relates to the field of UAV design, in particular to a multi-configuration coordinated design method for UAV wings with flying wing layout. Background technique [0002] Flying wing layout UAV has the advantages of high aerodynamic efficiency, good stealth performance, light structure weight, and large effective loading space. China's B2 bomber, X47B UAV, RQ180 UAV, France's "Neuron" and Britain's "Raytheon", etc. Since the wing is the main component that generates the lift of the whole aircraft, the layout of the wing determines the use of the UAV. For large aspect ratio and small sweep angle, high stealth requires UAV to have a larger sweep angle. Therefore, UAVs designed for high stealth cannot meet the requirements of long-endurance flight, and UAVs designed for long-endurance flight cannot meet the requirements of high stealth capability, which will lead to limitations in the execution of missions for Type I UAVs .

Problems solved by technology

[0004] Flying wing layout UAV multi-configuration wing design will become a major technological change in the field of UAV design in the future, but from the perspective of aerodynamic design, the aerodynamic performance of the whole aircraft is completely different with different wings, especially for For the flying wing layout, its vertical, horizontal, and directional aerodynamic characteristics will change significantly, and at the same time, the aerodynamic focus and center of gravity matching of the whole aircraft will also change, which will bring a series of UAV matching and control problems
