UH-1N Category II Propulsion System Evaluation

Abstract

This report presents the results of the propulsion system evaluation conducted during the UH-1N Category II systems evaluation program. The propulsion system was adequate for accomplishment of mission objectives, but several improvements should be made. Flight Manual changes were considered necessary for engine starting, manual fuel control operation, engine topping parameters, and engine deterioration. Rotor overspeed occurred when the beep switch was actuated to increase rotor speed and when the collective pitch control was lowered. The fuel system should be redesigned to provide tank isolation in the event of combat damage. The fuel system should also be crashworthy. Operation, functional adequacy, accessibility, and ease of servicing of the drive and transmission components were acceptable.
