Abstract : A 12-month engineering study was conducted to define a digital flight control system capable of performing pilot-assist (augmentation) and pilot-relief (autopilot) functions. Basic control laws were synthesized and analyzed to satisfy current and projected requirements for high-performance naval aircraft. Software analysis procedures were applied to determine sample rates, word lengths, and memory capacity. A redundancy and monitoring approach was identified to further assess computer characteristics. Implementation options in areas of processor structure, input/output, and instruction repertoire were resolved. Representative portions of the overall flight control system were programmed on a small airborne computer (HDC-201) and verified by open- and closed-loop testing in conjunction with an analog simulation of the aircraft. A partial system specification was prepared reflecting overall study results. (Modified author abstract)
