A preliminary evaluation of the Navion as a lateral-directional flight simulator for use in the investigation of flying qualities criteria

摘要

A preliminary evaluation was made of a modified North AmericanNAvion airplane for use as a lateral -directional flight simulator inthe investigation of flying qualities criteria. Modification of thetest airplane was accomplished by installation of a three axis, variablefeedback autopilot and associated controls and sensing transducers. Ananalytical development, based on servo-analysis methods, suggested theratio of the numerator and denominator frequency terms in the roll angleto aileron control deflection transfer function as a possible flyingqualities criterion.
