Analysis of the motion simulation capabilities of reduced-degrees-of-freedom flight simulators

This thesis presents the results of a study conducted at the UTIAS Flight Simulation Laboratory on June 29-30, aimed at investigating the simulation realism that can be achieved using reduced-degrees-of-freedom flight simulator motion bases. The quality of motion produced by two different three-degrees-of-freedom motion bases was compared to that produced by a conventional six-degrees-of-freedom Stewart platform. The study involved two helicopter test pilots. The UTIAS Flight Research Simulator was used to simulate a Bell 205 helicopter for four different ADS-33 maneuvers and a Sea King helicopter for helicopter deck landings on a Canadian Patrol Frigate. Cooper-Harper handling qualities ratings for each maneuver were collected, along with motion rating scales, TLX workload ratings, questionnaires and pilot performance measures. The analysis of the results revealed that reduced-degrees-of-freedom motion bases are more than capable of producing motion quality comparable to that produced by the six-degrees-of-freedom motion base and serious thought should be given to the design of these potentially cheaper alternative motion bases for the application in modern flight simulation.
