EFFECT OF EROSION RESISTANT BOOTS ON UH-1B/D TAIL ROTOR BLADES

Abstract

The report presents the results of a flight test program conducted to evaluate erosion boots installed on the outboard 18 inches of the UH-1 helicopter tail rotor blades. The report is not concerned with the erosion resistant qualities of the boot, but with the effect of the boot installation on the balance, operation, and fatigue life of the UH-1B/D tail rotor dynamic components. Loads as measured during flight tests of the tail rotor with the boots installed are compared to loads measured using a standard tail rotor. In both the balanced and unbalanced conditions no detrimental effects were encountered. The oscillatory loads recorded in either condition would not cause fatigue damage and no problems in operation were obtained with the boots installed.
