Public award description
A SYSTEMATIC TESTING OF UAV-TYPE PROPELLERS SHALL BE CONDUCTED THAT PRODUCES A BENCHMARK FAR FIELD ACOUSTIC DATABASE APPROPRIATE FOR PROPELLER NOISE VALIDATION. SIMULATED FLIGHT CONDITIONS SHALL BE USED FOR THESE TESTS USING AN OPEN JET ANECHOIC WIND TUNNEL. ADHERENCE TO PROPER OPEN JET PROPELLER WIND TUNNEL CONDITIONS THAT PRODUCE MEANINGFUL AERODYNAMIC DATA SHALL BE REQUIRED. AERODYNAMIC LOADS FOR A RANGE OF PROPELLERS WITH CLEAN INFLOW THAT HAVE DIFFERENT BLADE NUMBERS, DIFFERENT PITCH, AND DIFFERENT DIAMETERS SHALL BE GENERATED USING BOTH A BLADE ELEMENT APPROACH AND A COMPUTATIONAL FLUID DYNAMICS (CFD) APPROACH. IN ADDITION, INSTALLATION EFFECTS SUCH AS ENGINE EXHAUST FLOW AND BLUFF BODY WAKES INTRODUCED INTO THE PROPELLER INFLOW SHALL BE TESTED. THESE DATA SHALL BE USED AS INPUT TO NASA S ACOUSTIC PREDICTION CODE.
