Flight Control Actuation System for the B-2 Advanced Technology Bomber 911112
The B-2 Advanced Technology Bomber has a very unconventional shape and unique requirements to fulfill its mission. In order to satisfy the demanding requirements for the B-2's excellent handling qualities a flight control system was developed with unrivaled performance and sophistication. A key subsystem of the flight control system is the Flight Control Actuation System (FCAS). The FCAS is a self-contained quadraplex system that includes hydraulic actuators with direct drive servovalves for all surfaces, electronic actuator loop closures, and redundancy management.
