Abstract

In a system for supplying power to ROSAR transmitting and receiving antennas that are integrated into the tip of a helicopter rotor blade, wind energy is converted directly into electrical energy locally at the rotor blade tip.

Claims

1. Apparatus for supplying power to transmitting and receiving antennas of a ROSAR system that are integrated at tips of a helicopter rotor blade and operate on-line in near real time, in pulse frequency or in the cm- or mm-wavelength range, said apparatus comprising:

at least one transponder card, arranged at said tips of said rotor blade and having at least one flat channel extending therethrough; and

a plurality of fluttering bands that are integrated into said at least one flat channel extending through said transponder card, whereby wind energy is converted to electrical energy.

2. The apparatus for supplying power in accordance with claim 1, wherein:

the bands have magnetic layers; and

a flat coil having one or more turns is positioned opposite said bands.

3. The apparatus for supplying power in accordance with claim 2, wherein the bands are electrically connected to one another in series or parallel.

4. The apparatus for supplying power in accordance with claim 1, wherein:

said at least one transponder card is flat and streamlined in its outer shape; and

height of said at least one transponder card does not exceed 10 mm.

5. The apparatus for supplying power in accordance with claim 4, wherein:

the bands have magnetic layers; and

a flat coil having one or more turns is positioned opposite said bands.
