摘要：
停转旋翼飞行器长期以来一直被认为是理想的垂直起降（VTOL）飞行器，适用于在两个飞行阶段中时间均等的任务，如农业监测、搜索救援和最后一英里配送。其特点是中央升力面在VTOL模式下旋转以产生垂直推力，并在前飞时锁定以产生被动升力，这使得停转旋翼在两种模式下都具有高效率的潜力。然而，由于飞行模式之间的空气动力学和稳定性冲突，实际实施一直不可行。在这项工作中，我们提出了SPERO（停转五旋翼），一种停转旋翼无人机（UAV），具有翻转和锁定机翼、主动压力中心机制、推力矢量配平、五旋翼架构以及协调几何和控制器重构的十一状态机飞行控制器。此外，SPERO为停转旋翼无人机建立了一个可推广的设计和控制框架。这些创新共同克服了停转旋翼飞行中长期存在的挑战，并实现了VTOL与前飞之间首次稳定的双向过渡。
英文摘要：
Stop-rotor aircraft have long been proposed as the ideal vertical takeoff and landing (VTOL) aircraft for missions with equal time spent in both flight regimes, such as agricultural monitoring, search and rescue, and last-mile delivery. Featuring a central lifting surface that rotates in VTOL to generate vertical thrust and locks in forward flight to generate passive lift, the stop-rotor offers the potential for high efficiency across both modes. However, practical implementation has remained infeasible due to aerodynamic and stability conflicts between flight modes. In this work, we present SPERO (Stopped-Penta Rotor), a stop-rotor uncrewed aerial vehicle (UAV) featuring a flipping and latching wing, an active center of pressure mechanism, thrust vectored counterbalances, a five-rotor architecture, and an eleven-state machine flight controller coordinating geometric and controller reconfiguration. Furthermore, SPERO establishes a generalizable design and control framework for stopped-rotor UAVs. Together, these innovations overcome longstanding challenges in stop-rotor flight and enable the first stable, bidirectional transition between VTOL and forward flight.
