| 摘 要： | 采用均匀试验设计的方法, 以后掠排翼式飞艇为初始气动外形, 后翼的轴、法向坐标为设计变量, 升力、阻力系数和升阻比为目标函数, 通过CFD结合响应面近似理论, 建立了气动参数的二阶响应面优化模型, 并针对排翼式飞艇的升阻特性进行了优化设计. 研究结果表明: 响应面方法是解决气动优化问题的一种行之有效的方法;优化后排翼式飞艇的气动性能得到明显改善, NACA0020, NACA0030, NACA0040排翼式飞艇的升阻比分别提高了9.61%, 6.08%, 13.08%; 飞翼的轴向和法向位置对各气动参数的影响不尽相同, 升力系数C_rm l和升阻比k对轴向位置更为敏感, 而轴向和法向位置对阻力系数C_d的影响则基本相当.
