RESULTS OF MAIN ROTOR RADAR BLADE FLIGHT TESTS, MODEL UH-1B, S/N AF622023

Abstract

Main rotor blades configured with leading edge radar antennas were installed on a Model UH-1B Helicopter, S/N AF 62-2023, Bell No. 543, for both ground and flight tests. Load level tests and basic electromagnetic radiation pattern tests were successfully completed. Load level tests confirmed previous measurements. All measured loads and vibrations were identical to production 204 blades. Flight characteristics are identical to a production UH-1B helicopter. Radiation pattern tests were very successful and proved that the use of rotor blade antennas as a radar transmitting device is feasible. Based on preliminary analysis of flight test data, it is concluded that use of the main rotor blades for radar transmissions is practical.
