Aerospace Fluid Power - Materials and Characteristics of Flight Control Servoactuators of Various Aircraft
This SAE Aerospace Information Report (AIR) defines the materials, strength, and finishes utilized in current linear hydraulic flight control actuators. To keep the information at a relevant minimum, only cylinders (barrels), glands, and pistons are listed. Also identified are the reasons for the material selection and any pertinent comments. All data were collected from the respective suppliers.
This document is a list of commonly used materials and associated characteristics for key components of linear flight control servo actuators for most current aircraft. Since the last revision, many new fixed and rotary wing aircraft have entered service warranting their inclusion in this five year update.
