RESEARCH AND DEVELOPMENT FOR FAULT TOLERANT FLIGHT CONTROL SYSTEM - PART 2 FLIGHT EXPERIMENTS

摘要

This paper describes flight experiments of a fault tolerant flight control system to guide and land an airplane suffering from reduced controllability or other restrictions caused by unexpected failures safely to a suitable airport. The system aims at a further reduction of the fatal accident rate and preventing the number of fatal accidents from increasing in proportion to the number of operations. An online flight trajectory optimization system, an intelligent collision avoidance system, an adaptive control system with neural network, and flight control by engine thrust are proposed as essential technical elements of the fault tolerant control system needed to accomplish emergency landings safely.This paper outlines the aircraft used for flight evaluation of the technical elements and introduces typical flight experiment results that demonstrate the applicability of each element to the proposed fault tolerant flight control system.
