Abstract:

CONTRACTOR WILL EXAMINE THE FEASIBILITY OF UTILIZING ITS PIEZOCERAMIC CHIPS AS ACTUATORS FOR VARIABLE TWIST PROPELLERS IN UAV APPLICATIONS. THESE ACTUATORS WILL BE UTILIZED TO OPTIMIZE THE TWIST OF RIBSTIFFENED ELASTOMERIC PROPELLER BLADES ON A BLADE-ELEMENT-BY-BLADEELEMENT BASIS SO THAT EACH SEGMENT OF THE BLADE IS OPTIMIZED WITH RESPECT TO HELICAL INFLOW ANGLE INDEPENDENTLY OF EACH OTHER SEGMENT. THUS A BLADE-ELEMENT TUNED OPTIMUM WILL BE SOUGHT. THE LOAD ABSORBED BY THE PROPELLER IS PROPOSED TO BE VARIED ELECTRICALLY; THE PROPELLER HUB CONTAINS A BUILT-IN GENERATOR TO PROVIDE POWER TO THE SYSTEM WITHOUT COMMUTATION.
