reportActive / Technical Report | Accession Number: AD0785573 | Open PDF

Abstract:

The investigation was performed in order to identify deficiencies in military specifications and standards concerning electrical systems in U.S. Army helicopters. The three areas of concern that have impact on helicopter reliability and maintainability are Design requirements qualification test requirements, procedures, and practices and quality assurance provisions and requirements. The helicopters selected are the AH-1G Cobra, UH-1DH Iroquois, OH-6A Cayuse, CH-47A Chinook, and the CH-54A Tarhe. Schematics of each model helicopter electrical system were analyzed, and a composite schematic was constructed to represent all circuits, equipments, and component parts of all models. This composite schematic provided a baseline system on which to build an electrical system documentation tree.
