Special Power Train Requirements for the Next Generation of Rotary-Wing Aircraft,

Abstract : The omnipresent rotary-wing drive system requirements for minimum weight with maximum reliability will be compounded in the future by additional restrictions on size, damage tolerance, cost, and ease of assembly and maintenance. The authors present their view of the form of these restrictions and provide some broad insight into possible approaches designed to improve the performance of rotary-wing drive systems. We also provide specific examples of extensions of current technology and some speculation about potential applications.
