Composite Main Rotor Blade AH-64 Guardian

摘要

The AH-64E Apache Guardian was fielded in 2012 and implemented several tactical improvements over the AH-64D Apache Longbow. Aircraft performance was greatly improved by the addition of 701D engines, an improved rotor drive system with split face gear technology, and new composite main rotor blades (CMRB). While composite secondary structures are not new to the Apache, the introduction of a primarily composite main rotor blade was new to the AH-64 platform and its maintenance program.
