The Flight Research Laboratory at Princeton University is engaged in an experimental program to investigate a variety of approaches to digital control by actual flight test. Experimentation is being conducted with 6 DOF variable-response research aircraft (VRA), which is equipped for direct side-force control, direct-lift control, feedback of all motion variables, and multiple pilot command modes. VRA avionics have been augmented by a microprocessor digital flight control system (Micro-DFCS). The digital control laws operate in conjunction either with the 'bare airframe' dynamics of the VRA or with the dynamics of a simulated aircraft. The initial flight control computer program CAS-1 provides three longitudinal control options: direct (unaugmented) command, pitch rate command, and normal acceleration systems designed by linear-quadratic control theory.
