F-14 Flight Control Law Design, Verification, and Validation Using Computer Aided Engineering Tools.

Abstract

The analog flight control computers (FCC's) in the F-14A/D airplane are currently being replaced with digital FCC's. This FCC upgrade will also include significant flight control law modifications which are designed to improve the aircraft's flying qualities throughout the operating envelope. Teamed with engineers from Grumman Aerospace, the NAWCAD was tasked as the lead activity in the total system development, integration, and testing of the new digital flight control system. These tasks included the development of improved control laws for both the up and away maneuvering flight envelope as well as the takeoff and landing configurations. These control laws engineering tools that were available on the main simulation computer system as well as desk top computer based systems. This paper specifically addresses the methods in use for the F-14 Digital Hight Control System (DFCS) program, however many of the methods used in this effort are currently being applied to the F-18E/F, V-22 and EA-6B programs.
