Abstract
THIS IS A PROPOSAL TO PRODUCE AN ACOUSTIC ARRAY DESIGN SUITABLE FOR MAKING ACOUSTIC MEASUREMENTS OF MODEL HELICOPTERS IN A WIND TUNNEL. THIS "FEASIBILITY DESIGN" WILL DEMONSTRATE THE THEORETICAL FEASIBILITY OF SUCH A WIND TUNNEL ARRAY, AND WILL QUANTIFY THE PERFORMANCE OF SUCH AN ARRAY. THE WORK WILL INVESTIGATE THE DESIGN TRADEOFFS AVAILABLE AND WILL ESTABLISH THE COMPUTATIONAL REQUIREMENTS FOR ARRAY SIGNAL PROCESSING AS WELL AS MECHANICAL AND ELECTRICAL TOLERANCES FOR ARRAY FABRICATION. THE REQUIRED ARRAY SIGNAL PROCESSING WILL BE UNIQUE IN THAT IT WILL TAKE INTO ACCOUNT THE SIGNIFICANT MACH NUMBERS OF THE WIND TUNNEL AIRFLOW. IT IS EXPECTED THAT THE DESIGN WILL BE ABLE TO PROVIDE FREQUENCY COVERAGES OF 5 - 6 OCTAVES, SIGNIFICANT REJECTION OF AMBIENT NOISE AND REFLECTED NOISE, AND ACOUSTIC IMAGING CAPABILITY.
