Abstract

Abstract: In this paper, the aerodynamic parameters of the middle wing of a special configuration laminar flow in high speed cruise were optimized. The characteristics of lift and drag were optimized by means of airfoil modification of middle wing section based on numerical simulation using the transition model. Besides, the effects of the middle wing position on transition were researched for providing a basis for improving the cruising torque characteristics of the flight. The applicability of the calculation model was illustrated by comparing the calculation and wind tunnel test results of the original laminar flow airfoil and one traditional airfoil. The original laminar airfoil was modified for improving the lift coefficient at the same attack angle and reducing the cruise attack angle, which enlarged the laminar region and improved the laminar characteristics at the high speed cruising condition. Finally, the aerodynamic calculations of different middle wing section translation configurations were conducted and the results showed that the laminar region changed little along with the wing section translated. And the characteristics of lift and drag had been turned out to be affected little by comparing the lift and drag coefficients of different translational configurations at the same attack angle, which was convenient for the further works on torque optimization by translating the middle wing section.

Key words: middle wing section, transition model, aerodynamics, airfoil optimization, laminar flow characteristics
