Abstract

The invention discloses a method for processing airfoil surface load, which comprises the steps as follows: step 1: applying pressure on an airfoil surface to be measured; step 2: forming a pressure distribution three-dimensional model of the airfoil surface to be measured so as to obtain functional relationship in the pressure distribution three-dimensional model; step 3: forming a finite element planar model of the airfoil surface to be measured; step 4: mapping the finite element planar model of the airfoil surface to be measured by using the functional relationship in the step 1 as a mapping function so as to form a finite element load distribution model of the airfoil surface to be measured. Compared with prior art, the method for processing airfoil surface load of the invention considers the comparison between total load and total moment before and after load processing, and considers the comparison between a pressure distribution pattern and a finite element node load distribution pattern so that a designer could obviously judge the rationality of aerodynamic load process.

Description

Technical field [0001] The invention relates to the technical field of aircraft, in particular to a wing surface load processing method. Background technique [0002] The processing of aerodynamic loads must consider the comparison of the total load and the total moment before and after the load processing, as well as the comparison of the CP (pressure) distribution pattern and the finite element node load distribution pattern. In the process of aerodynamic load processing, the problem that needs to be solved is how to use the function of three-dimensional graphic display to visually compare and analyze the CP distribution and the finite element node force distribution. [0003] In the prior art, the total load and the total moment before and after load processing are usually compared, and the error after processing is controlled at 5%, and corrections are made if it exceeds 5%, ignoring the load distribution shape, which has certain limitations. [0004] Therefore, it is desirable ...
