摘要:
One example of a rotorcraft blade control system includes a mechanical linkage (117a,b) to connect to a rotorcraft blade (104) including a feather axis (150) and a pneumatic muscle (107a,b) connected to the mechanical linkage (117a,b). The system also includes a movement member connected to the mechanical linkage (117a,b), the pneumatic muscle (107a,b) and the movement member to move the mechanical linkage (117a,b) to control movement of the rotorcraft blade (104) on the feather axis (150). The pneumatic muscle (107a,b) can be a first pneumatic muscle and the movement member can be a second pneumatic muscle or a bias spring.
摘要:
Some examples of techniques to cost-effectively embed fiber optic cables (306) in laminate structures and to terminate the fiber optic cables (306) on the surface of the laminate for robust and easily-repairable connections can be implemented in rotorcraft composites (302). To position a cable (306) in the rotorcraft composite (302), a length of a fiber optic cable (306) is embedded between layers of a composite rotorcraft material (300). The length of the fiber optic cable (306) is oriented in a substantially S-shape between the layers. An end of the length of the substantially S-shaped fiber optic cable (306) is extended to an edge of the composite rotorcraft material (300). The end of the length of the substantially S-shaped fiber optic cable (306) is terminated at the edge of the composite rotorcraft material (300) in either a storage area or easily machinable embedded connection.
