The invention discloses an aeroelastic test platform which comprises a machine body, wherein the machine body comprises wings and a plurality of supporting rods sequentially arranged in the spanwise direction of the wings, the wings comprises a plurality of wing sections connected in sequence, the supporting rods are arranged at the joints of the adjacent wing sections, one end of each supporting rod is provided with a power device, and the other end of each supporting rod is provided with an empennage; a power device which is used for providing flight power for the machine body, wherein an undercarriage is arranged below each supporting rod; a flight control system which is arranged on the machine body and used for controlling the flight attitude of the machine body; and a grating measurement system which is arranged on the machine body and is used for measuring the strain and the acceleration of each wing section and each supporting rod in the flight process. According to the aeroelastic test platform, the elongation and the aspect ratio can be adjusted according to test requirements, the body structure, especially wings, has great flexibility, and the characteristics of high aspect ratio, low structural rigidity and low wing load of a high-altitude long-endurance unmanned aerial vehicle can be intuitively reflected.
本发明公开一种气弹试验平台,包括:机体,机体包括机翼和沿机翼的展向依次设置的多个撑杆,机翼包括依次连接的多个机翼段,撑杆设置于相邻机翼段的连接处,每个撑杆的一端设有一个动力装置,另一端设有尾翼,动力装置用于为机体提供飞行动力,每个撑杆下方设置有起落架;飞控系统,飞控系统设置于机体上,用于控制机体的飞行姿态;光栅测量系统,光栅测量系统设置于机体上,用于测量飞行过程中每个机翼段和撑杆的应变和加速度。该气弹试验平台可根据试验要求,调节展长和展弦比,机体结构尤其是机翼具备很大的柔性,可直观反映高空长航时无人机大展弦比、低结构刚度、低翼载的特点。
