Abstract

The invention discloses a rapid airfoil design method based on an online agent model algorithm. The rapid airfoil design method comprises the following steps: 1) determining a variable range of an airfoil; 2) initializing sampling points, and calculating CFD simulation results of the corresponding sampling points; 3) constructing an online agent model by using the decision tree; and 4) performingparameter optimization design of the aircraft airfoil based on the fitted agent model and the multi-objective optimization algorithm. According to the method, the agent model technology, the multi-objective optimization technology and the aircraft airfoil design are fused together, so that a better aircraft airfoil design scheme can be obtained at a relatively high speed and a relatively low cost.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and in particular relates to an aircraft airfoil design method, which is suitable for general-purpose aircraft airfoil design. Background technique [0002] Wing design is an important part of aircraft design, and airfoil design is the primary basis of wing design. According to the different uses and flight conditions of the aircraft, it is necessary to design a suitable airfoil for the aircraft. For example, the wing profile of a transport aircraft is thicker to provide greater lift and stable performance, and the wing profile of a supersonic aircraft is generally thinner to reduce drag. The design of the airfoil directly affects the development of the follow-up links, so the engineering practice has high requirements for the design efficiency of the airfoil, that is, it is required to design an airfoil with good performance in the shortest possible time.
