In-Service Reliability Data of Continuously Active Ballscrew and Geared Flight Control Actuation Systems
An industry survey has been completed to determine the incidence of jam and excessive backlash in rotary and linear mechanical actuators subject to "primary flight control like" 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.
Rationale: The lack of in-service relevant data on unacceptable wear/backlash and jam failure rates of ballscrew and geared flight control actuation systems has been identified as one factor preventing electromechanical actuators from being more thoroughly considered as a primary control surface actuator. This document is written to satisfy this in-service reliability data need.
