针对超声速飞行器在大气层内飞行引起严重的气动光学效应问题，提出利用变坡度的斜坡型涡流发生器（Ramp-VG）阵列，通过在飞行中调整不同坡度参数，在跨速域工况下实现动态光场调控，抑制不同飞行任务剖面下的光学畸变。基于大涡模拟（LES）方法与光线追迹法，建立气动光学效应计算与评估模型，系统揭示Ramp-VG坡度参数对湍流结构演化与光传输特性的影响规律。研究结果表明适应边界层特性的Ramp-VG阵列能够有效改善光窗表面的流动特性，推迟湍流转捩点，显著抑制因凹窗后缘台阶流动分离和湍流发展引起的光学畸变，在Ma3.2工况下采用5°坡度使波前畸变降低24.6%，而在Ma2工况下15°坡度实现畸变抑制率达46.5%。进一步揭示了变坡度Ramp-VG阵列流场与光场调控机理，提出变坡度Ramp-VG阵列光场调控策略，为在不同马赫数、飞行高度和成像模式下的光学性能优化，以及复杂飞行条件下的光学窗口设计提供了新思路。

To address the aero-optical effects caused by supersonic vehicles flying within the atmosphere, this study proposes a variable-slope Ramp-VG (Ramp Vortex Generator) arrays as a morphing strategy. By adjusting slope parameters, dynamic light field regulation is achieved across transonic and supersonic conditions, effectively reducing optical distortions under different flight mission profiles. Based on Large Eddy Simulation (LES) and ray-tracing methods, a calculation and evaluation model for aero-optical effects is established to compare the performance of variable-slope Ramp-VG arrays under different flight speeds. The results demonstrate that Ramp-VG arrays adapted to boundary layer characteristics can effectively improve the flow characteris-tics over the optical window, delay turbulent transition, and significantly suppress optical distortions caused by flow separation and turbulence development at the rear edge of recessed windows. At Ma 3.2, a 5° Ramp-VG reduces wavefront distortion by 24.6%, while a 15° Ramp-VG at Ma 2 achieves a distortion suppression rate of 46.5%. Furthermore, the study reveals the flow field and optical field regulation mechanisms of variable-slope Ramp-VG arrays and proposes a light field regulation strategy. This provides new insights for optimizing optical performance under different Mach numbers, flight altitudes, and imaging modes, as well as for designing optical windows under complex flight conditions.
