Apparatus and methods for structurally-integrated conductive conduits for rotor blades

An elongated rotor blade, comprising:

• a body having a root portion and a distal portion spaced apart from the root portion;
• a device coupled to the body;
• and
• a conductive conduit disposed within the body and extending between the root portion and the device, the conductive conduit having at least one conductive lead formed within a matrix material, the conductive lead being adapted to transmit at least one of power and data signals between the root portion and the device.

An aircraft, comprising:

• a fuselage;
• and
• a propulsion system operatively coupled to the fuselage and including a rotor having at least one elongated blade for generating aerodynamic lift, the elongated blade including:
• a body having a root portion and a distal portion spaced apart from the root portion;
• a device coupled to the body;
• and
• a conduit assembly disposed within the body and extending between the root portion and the device, the conduit assembly including a main body assembly having at least one of a conductive lead, a fluid line, and an optical fiber disposed within a matrix material, the conduit assembly extending from the root portion to the device.

A method of operating a rotor driven aircraft, comprising:

• providing an elongated blade operatively coupled to a fuselage, the elongated blade including a body having a root portion and a distal portion spaced apart from the root portion;
• providing a conduit assembly disposed within the body and extending between the root portion and a device coupled to the elongated blade and spaced apart from the root portion, the conduit assembly including a main body assembly having at least one of a conductive lead, a fluid line, and an optical fiber disposed within a matrix material, the conduit assembly extending from the root portion to the device;
• rotating the elongated blade to produce an aerodynamic lifting force;
• and
• providing at least one of electrical power, low-voltage signals, hydraulic pressure, pneumatic pressure, and optical signals through the conduit assembly to the device.
