变构型飞行器根据飞行任务在线改变气动外形,可在宽飞行包线内保持优异气动性能,成为当前航空航天领域的研究热点。针对变构型飞行器气动外形设计面临的在线/离线变量一体化协调与多剖面异构约束的挑战,发展了一种面向多任务的跨域变构型飞行器气动设计方法。该方法采用在线与离线两类设计变量参数化气动外形,构建了内、外两层耦合优化框架,旨在实现全剖面性能最优并满足各剖面约束。将该方法应用于可变后掠跨域飞行器,针对起降(最大升力)和高速飞行(最大升阻比、压心约束)剖面完成了气动外形优化。根据权重配置不同,优化构型在Ma=0.4工况,升力系数提升55.03%、56.85%;在Ma=6.0和Ma=10.0工况,升阻比分别提升1.16%、1.69%和0.94%、1.68%。压心变化均满足2%的设计约束,验证了该优化框架的有效性。
