Study on Optimization for High Lift Devices of Civil Aircraft Based on Rapid Calculation Method

Abstract

For the requirements of aircraft high lift device design, sorts out the key links of aerodynamic calculation, optimization design process and optimization strategy selection required for the parameters optimization. By selecting accurate and efficient calculation and analysis software, compiling high lift devices 3D model forming program and calculation analysis software pre-processing program, engineering application research of aerodynamic characteristic analysis software and the establishment of calculation analysis platform are carried out. Combined with the optimization software to establish the optimization process and define the optimization objectives and constraints, the optimization design platform for the parameters of the civil aircraft high lift device based on the multi-control section and multi-airfoil is realized. The optimization results of the calculation examples are in good agreement with the wind tunnel test results, which provide guarantee for the parameters optimization of the high lift devices of civil aircraft.
