Abstract
The Fly-By-Light Advanced Systems Hardware (FLASH) program is developing Fly-By-Light (FBL) and Power-By-Wire (PBW) technologies for military and commercial aircraft. FLASH consists of three tasks. Task 1 is developing the fiber optic cable, connectors, testers and installation and maintenance procedures. Task 3 is developing advanced actuators. Task 2, which is the subject of this paper, focuses on integration of fiber optic sensors and data buses with cable plant components from Task 1 and PBW, smart and thin wing actuators from Task 3 into complete centralized and distributed flight control systems. Laboratory demonstrations will show applicability to widebody transport and tactical aircraft. Products include high throughput processors, neutral network applications to maintenance diagnostics and reconfiguration, hardware upset recovery, active sidestick controllers and application of the SAE AS-1773A protocol to the flight control system bus. This paper overviews the requirements, objectives, key technologies and demonstrations for each of the FLASH flight control system developments. Companion papers provide additional description of the Tasks 1 and 3 as well as further details on the individual developments within Task 2.
