A four degrees of freedom, cockpit motion machine for flight simulation

Abstract

This Report gives a detailed account of the development of a machine for reproducing aircraft motions on a flight simulator cockpit. The four freedoms of the machine are actuated by hydraulic servos. The equipment is part of the piloted flight simulator facility used for research and development studies in the Aerodynamics Department of the Royal Aircraft Establishment at Bedford. The information presented concerns the engineering design and servo drive considerations involved. A description is given of the control and safety procedures used when operating the machine within the simulator facility. The limitations of the performance achieved are discussed both with a view to finding ways to improve the existing machine, and to point out those particular aspects of design which need careful attention and uncompromising implementation on any future project.
