Abstract: Disclosed is a combined antenna and helicopter rotor blade 101. The antenna comprises one or more electrically non-conductive rotor blades 101, each having an electrical conductor 210, 310 positioned parallel to the major axis of a respective rotor blade 101. A connection means 410, 412, 510, 521, 620, 623 is provided to connect the antenna to apparatus for the reception or transmission of radio waves which is located in the fuselage 102. Also disclosed is a communications system including apparatus for the transmission or reception of radio waves.

Abstract: Disclosed is a combined directional antenna and rotor blade for a helicopter. The antenna comprises three or more electrically non-conductive rotor blades, 801-805, each having an electrical conductor positioned parallel to the major axis of a respective rotor blade. Two of the electrical conductors on blades 801,805, having angular positions nearer to a predetermined angular position are connected via a connections means e.g. slip rings and brushes to apparatus for transmission or reception of radio waves. The remaining conductors on blades 802-804 may either be connected to the body of the helicopter or supplied with a signal out of phase compared to that supplied to the two electrical conductors. Also disclosed is a communications system including apparatus for the transmission or reception of radio waves. As the rotors rotate, different pairs of blades are selected to maintain the antenna pattern in the predetermined position. The antennae conductors may be formed from the metallic anti-erosion layer on the rotor leading edges or from heater coils embedded in the rotors under that layer (Fig 2 not shown).

Abstract: An antenna arrangement for a helicopter 100 comprises one or more electrically non-conductive rotor blades 101, each having an electrical conductor (210, 310, Fig 2) positioned parallel to the major axis of a respective rotor blade 101. Means are provided to connect the antenna to apparatus for the reception or transmission of radio waves which is located in the fuselage 102. The electrical conductor may be embedded within or affixed to the surface of the rotor blade or it may be a surface coating. The electrical conductor may also be used as a heater filament.
