대표청구항 ▼

1. A communication system comprising: a first communication module within a rotating frame of reference;a second communication module within a fixed frame of reference; anda hollow shaft at least partially within said rotating frame of reference, said first communication module and said second communication module in wireless communication at least partially through said hollow shaft, wherein said hollow shaft is a main rotor shaft of a rotary wing aircraft, said main rotor shaft rotatable about an axis of rotation. 2. The communication system as recited in claim 1, wherein said first communication module is a transmitter and said second communication module is a receiver. 3. The communication system as recited in claim 1, wherein each of said first communication module and said second communication module is a transceiver. 4. The communication system as recited in claim 1, wherein said hollow shaft is of a non-constant inner diameter formed within said main rotor shaft. 5. The communication system as recited in claim 1, wherein said hollow shaft is of a constant inner diameter. 6. The communication system as recited in claim 1, wherein said wireless communication is at a frequency above a waveguide cutoff frequency defined by said hollow shaft. 7. The communication system as recited in claim 1, further comprising a sensor within said rotating frame of reference, said sensor in communication with said first communication module through a communication line, said first communication module in close proximity to said second communication module. 8. The communication system as recited in claim 1, further comprising a communication line connected to said first communication module and a first antenna within said rotating frame of reference, said first antenna in close proximity to a second antenna of said second communication module. 9. The communication system as recited in claim 8, wherein said first antenna is a rotating disk antenna and said second antenna is a fixed disk antenna. 10. The communication system as recited in claim 8, wherein said first antenna is a probe and said second antenna is a coil, or probe. 11. The communication system as recited in claim 8, wherein said communication line is an optical fiber. 12. A method of wireless communication comprising: wireless communicating between a rotating frame of reference and a fixed frame of reference at a frequency above a waveguide cutoff frequency defined by a hollow shaft at least partially within the rotating frame of reference, wherein the hollow shaft is a main rotor shaft of a rotary wing aircraft.
