Product Code:SAE AIR5713
Title:In-Service Reliability Data of Continuously Active Ballscrew and Geared Flight Control Actuation Systems
Issuing Committee:A-6b3 Electro-Mechanical Actuation Committee
Scope:An industry survey has been completed to determine the incidence of jam and excessive backlash in rotary and linear mechanical actuators subject to 驴primary flight control like驴 duty cycles. The data is valuable for understanding how existing mechanical actuators behave in service, identifying areas for potential improvement and possibly being used as a reference to support future primary flight control system trade-off studies.【英文标准名称】:Leather.Testsforcolourfastness.Colourfastnesstoperspiration
