The application of metal matrix composite materials for helicopter transmission housings has many potential benefits including decreased deflections, increased dynamic component life and reduced vibration/noise levels. These improvements result from the selective stiffening of identified areas of high strain density. The effects of substituting metal matrix composites for a monolithic magnesium transmission housing has been evaluated bot analytically and experimentally. Noise levels and accelerations were mesured on a CH-47C forward transmission which was selectively stiffened. In addition, basic housing elements have been fabricated using high-modulus fibers (Fiber FP) via direct casting technology and tested to determine material properties. Initial test results indicate a three time increase of the modulus of elasticity of magnesium by the use of a Fiber FP/magnesium metal matrix composite material. (Wassmann)
