Abstract: A tiltrotor controls shield having a blade or wire substructure under a fragile spinner fairing improves bird strike durability. The present disclosure discloses a spinner wind fairing with a shield structure disposed thereunder for providing protection to the proprotor assembly components. The shield structure can segment a projectile, such as a bird, that penetrates the spinner fairing into a series of smaller and lower energy elements spread across a wider area, such that the rotor components can withstand the impact of the smaller elements without damage.

Abstract: A rotor blade system includes a first hub assembly having a first set of rotor blades and rotatably attached to a rotor mast, a second hub assembly having a second set of rotor blades and rotatably attached to the rotor mast, the second hub assembly being positioned at a space relative to the first hub assembly, a torque splitter device engaged with both the first hub assembly and the second hub assembly, and a locking device operably associated with the torque splitter device. The method includes rotating the first hub relative to the second hub via the torque splitter until the first set of rotor blades align with the second set of rotor blade about a common horizontal axis.
Abstract translation: 转子叶片系统包括具有第一组转子叶片并可旋转地连接到转子柱的第一轮毂组件，第二轮毂组件，其具有第二组转子叶片并可旋转地附接到转子杆，第二轮毂组件定位在 相对于第一轮毂组件的空间，与第一轮毂组件和第二轮毂组件两者接合的扭矩分配器装置，以及可操作地与转矩分配器装置相关联的锁定装置。 该方法包括经由转矩分配器使第一毂相对于第二轮毂旋转，直到第一组转子叶片围绕公共水平轴线与第二组转子叶片对准。
