Research abstract
TWO MECHANISMS ARE IDENTIFIED BY WHICH AN ELECTRICALLY CHARGED ROTORCRAFT MIGHT ACT AS A SOURCE OF ELECTROMAGNETIC RADIATION. THESE ARE NARROW BAND ELF RADIATION PRODUCED BY CURRENTS INDUCED BY ROTOR ROTATION AND BROADBAND ELECTROMAGNETIC RADIATION FROM P STATIC. IN ORDER TO DETERMINE WHETHER OR NOT RADIATION DUE TO THESE MECHANISMS IS DETECTIBLE A COMBINATION OF NUMERICAL MODELLING TECHNIQUES IS PROPOSED. THE GOAL OF THE ANALYSIS EFFORT IS TO PROVIDE ESTIMATES OF THE AMPLITUDES OF THE ELECTROMAGNETIC RADIATION DUE TO THESE TWO MECHANISMS AS A FUNCTION OF DISTANCE FROM THE ROTORCRAFT AND TO IDENTIFY THE BEST MEANS OF DETECTION OF THAT RADIATION.
