Abstract:

The metal tail section of the Cobra AH-1G HELICOPTER WAS ANALYZED TO DETERMINE AREAS NEEDING STRUCTURAL IMPROVEMENT. Three design concepts were selected for preliminary studies. Parameters affecting cost effectiveness and performance of fiber- reinforced composite fuselage structure were determined. Sensitivity analysis for reducing tail-section life-cycle costs were made and a math model for life-cycle costs, performance of composite fuselage and optimum design utilization was developed. Structural concepts selected for preliminary design study included monocoque sandwich clamshell, thin sandwich shell with longerons and frames, and integrally molded skinstringer clamshell.
