Reliability of the SST Wing-Sweep Actuation System

The United States SST must be capable of equaling or exceeding the reliability of today's subsonic jets to be profitable in scheduled revenue passenger service.

This paper describes reliability aspects of the wing-sweep actuation system for the Boeing SST in terms of (a) the hardware interfaces, functional purposes, and basic design concepts; (b) the basic requirements and design criteria established by Federal Air Regulations, Tentative Airworthiness Standards, FAA-established numeric goals, and Boeing-evaluated airline economic goals; and (c) reliability analyses relating the hardware design to specific requirements.
