摘要： A tension torsion strap by which a blade is connectable with a hub of a propulsor is provided. The tension torsion strap includes an elongate body formed to define attachment features at opposite ends thereof, the attachment features being connectable to the blade at one of the opposite ends and to the hub at the other of the opposite ends, fibrous materials extending along the elongate body and around the attachment features and pretension flanges elastically interposable between the hub and the elongate body. The pretension flanges are configured to maintain pretension in the fibrous materials above a predefined pretension level when the attachment features are connected to the blade and the hub.

摘要： A main rotor system for a rotary wing aircraft is provided including a lower rotor hub to which lower rotor blades are attachable. The lower rotor hub rotates about an axis in a first direction. A hollow rotor shaft extends through the lower rotor hub. The first end of the rotor shaft couples to a component of the rotary wing aircraft for rotation about an axis. An upper rotor hub arranged at the second end of the rotor shaft includes a plurality of similar upper rotor members equidistantly spaced about a circumference of the rotor shaft to form an open center aligned with a hollow interior of the rotor shaft. An opening configured to receive an upper rotor blade is formed between adjacent upper rotor members and the upper rotor hub is configured to rotate in a second direction, opposite the first direction.
摘要翻译：提供了一种用于旋转飞行器的主转子系统，其包括下转子轮毂，下转子叶片可附接到下转子轮毂。下转子毂绕第一方向的轴线旋转。中空的转子轴延伸穿过下转子毂。转子轴的第一端连接到旋转翼飞行器的一个部件，用于围绕轴线旋转。设置在转子轴的第二端处的上转子轮毂包括多个类似的上转子构件，其等距离地围绕转子轴的圆周间隔开，以形成与转子轴的中空内部对准的开放中心。构造成容纳上转子叶片的开口形成在相邻的上转子部件之间，并且上转子毂被构造成沿与第一方向相反的第二方向旋转。
