Abstract

Abstract: Flight tests are effective in efficiency evaluation for the laminar flow design technology, while the layout parameters of the test wing section are the starting point for the aerodynamic design of unmanned demonstrators. This paper confirms the engineering value of "the same design lift coefficient method", and innovatively designs a comprehensive verification test system for drag reduction effect of natural laminar airfoils, including numerical simulation, wind tunnel tests and flight tests. On this basis, the preliminary scheme of the unmanned verification aircraft with 1 t twin-fuselage configuration is improved. The influence of crucial layout parameters such as chord length, span length, installation position and installation angle on the performance of flight tests and the aerodynamic characteristics of the test wing section are analyzed based on CFD. The wind tunnel test results show that the layout parameters of the demonstrator test wing section are reasonable, the longitudinal static stability of the demonstrator is moderate, and the test section can maintain a large range of stable two-dimensional flow area, thereby satisfying the flight test verification requirements.

Key words: natural laminar flow, aerodynamic layout design, laminar airfoil, flight test, wind tunnel test
