Title:
HELICOPTER ROTOR BLADE RADAR ANTENNA
Corporate Author:
BELL HELICOPTER TEXTRON INC FORT WORTH TX
Report Date:

Abstract:
The use of the helicopter main rotor blade as a scanning radar antenna can achieve significant reduction in weight, along with greatly improved performance, compared with conventional antennas. Material is cut from the existing blade to install the antenna so that no additional weight is added. The natural rotor motion scans the antenna so that the usual scanning motor and associated drive are completely eliminated. No radome is necessary an important point because helicopters are now being designed with speeds of over 200 knots. The narrow beamwidth can make possible a radar with much greater resolution than any available for helicopter use today.
