跨速域飞行器在快速部署、持久侦察与高速投送等领域展现出广阔应用前景，其设计核心挑战在于依靠单一气动布局难以兼顾复杂飞行工况需求且单体平台尺寸较大难以向集群应用场景拓展。本研究提出一种具备集群部署潜力且宽速域性能均衡的变体滑翔飞行器构型，融合乘波体与旋转伸缩机翼气动布局，建立了完整的设计、优化和性能评估框架，实现跨速域变体滑翔飞行器从任务需求到性能评价的完整闭环。在总体参数评估方面，提出了基于多阶段再入飞行走廊的总体参数评估方法；在气动外形优化方面，建立了乘波体尾部整流罩宽速域优化方法和变体机翼全局-梯度两阶段优化策略；在飞行器任务能力评估方面，基于hp-RPM (hp-adaptive Radau Pseudospectral Method) 方法完成飞行器可达域计算和任务能力评估，探索出适用于该布局的俯冲-跃升减速策略，可在不改变布局的情况下突破准平衡滑翔软约束完成预定减速任务，使飞行器具备更强的载重能力。

Cross-speed-range vehicles have shown significant application potential in rapid deployment, persistent reconnais-sance, and high-speed delivery. However, their development faces core challenges: a single aerodynamic configura-tion is often insufficient to accommodate complex flight condition requirements, and large monolithic platforms are difficult to adapt for swarm-based deployment. This study proposes a morphing glide vehicle configuration with swarm deployment capability and balanced cross-speed-range performance. The design integrates a waverider body with rotating and telescopic wings. A comprehensive framework is established, encompassing design, optimization, and performance evaluation, forming a closed-loop development process from mission requirement definition to perfor-mance validation for cross-speed-range morphing glide vehicles. In the system-level assessment, a parameter evalua-tion method based on a multi-stage reentry flight corridor is proposed. For aerodynamic optimization, a cross-speed-range optimization method is developed for the waverider tail fairing, along with a two-stage global–local optimization strategy for morphing wing design. Based on the hp-adaptive Radau Pseudospectral Method (hp-RPM), reachable domain computation and mission capability evaluation are performed. A dive–climb deceleration strategy suitable for this layout is proposed, enabling the vehicle to overcome quasi-equilibrium glide constraints and fulfill deceleration requirements without modifying the configuration, thereby improving its payload capacity.
