Structural Applications of Advanced Composite Materials to Helicopters.

Abstract

Initial results of a continuing study have established a technical base for the application of advanced composites to helicopters. A reinforced-composite application analysis relative to two existing helicopters is presented, including the analysis of the rotor and hub systems, drive system, airframe applications. Initial efforts on the rotor blade have indicated that the anticipated advantages of composites can be achieved. Several rotor blade cross sections are evaluated on a stiffness basis to demonstrate the relative superiority of each design from a minimum weight standpoint. The position of an all-advanced-composite plastic rotor blade is identified in the parametric field, and the baseline preliminary design blade is established.
