Abstract

Using computational fluid dynamics method, numerical simulation is carried out on the typical two-dimensional multi-segment wing with the deflection hinged flap configuration of spoiler, and the influence of the down-deflection of the spoiler on the Reynold number effect of the multi-segment wing is studied. the result show that: Within the scope of this article, 1) The camber effect produced by the deflection of spoiler can increase lift at small angles of attack but has a limited effect on the C_L-MAX; 2) The spoiler down-deflection configuration has a limited affection of Reynold number in linear segment, which is more affected near stall, the slope of C_L is affected by Reynold number.
