Abstract:

The purpose of this program was to develop the technology of applying fiber-reinforced composite materials to helicopter joints and attachment fittings that permit disassembly of major components. A generic design methodology approach was used to make the data developed applicable to ongoing and future helicopter programs. A detail design, analysis, and testing program was carried out on the three joint and fitting concepts selected wrapped tension fittings, gearbox attachment fittings, and seat attachment fittings. The scope of the study included analytical design tools, including finite element computer analysis fabrication techniques, with special emphasis on weight and cost effectiveness considerations structural integrity testing, including static, dynamic, failsafesafe-life, and ballistic tolerance considerations and nondestructive inspection NDI techniques.
