Abstract

The invention discloses a method for processing airfoil loads. The airfoil load processing method includes the following steps: Step 1: applying pressure to the airfoil to be measured; Step 2: forming a three-dimensional model of the pressure distribution of the airfoil to be measured, thereby obtaining the functional relationship in the three-dimensional model of the pressure distribution; Step 3 : form the finite element chord plane model of the airfoil to be tested; Step 4: map the finite element chord plane model of the airfoil to be tested with the functional relationship in the step 1 as the mapping function, thereby forming the finite element chord plane model of the airfoil to be tested Element load distribution model. Compared with the prior art, the airfoil load processing method of the present invention not only considers the comparison of the total load and the total moment before and after the load processing, but also considers the comparison of the pressure distribution form and the finite element node load distribution form, so that the designer can intuitively judge Rationality of aerodynamic load handling.

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 aerodynamic load processing should 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 to...
