Rotor blade with structurally-integrated conduit assembly

Structurally-integrated conductive conduits for rotor blades are disclosed. In one embodiment, an elongated rotor blade (100) includes a body having a root portion (102) and a distal portion (106) spaced apart from the root portion (102), a device coupled to the body, and a conduit assembly (120) disposed within the body and extending between the root portion (102) and the device. The conduit assembly (120) includes a main body assembly (121) having at least one of a conductive lead, a fluid line, and an optical fiber disposed within a matrix material, the conduit assembly (120) extending from the root portion (102) to the device. In alternate embodiments, the device may comprise an actuator, a smart actuator, a piezoelectric material, an electromagnetic device, an electromechanical device, a hydraulic actuator, a pneumatic actuator, a light, and a sensor.
