An Investigation of the Longitudinal Handling Qualities of a Variable Stability Flight Simulator

摘要

An investigation of the longitudinal handling qualities of the variable stability flight simulator, converted from a C-11B Instrument Flight Trainer, found the qualities to be an unrealistic representation of aircraft motion. Nonlinearities found in the dc servo drive circuits were caused by the dc servo drive motor's starting voltage, striction, misalinement of the motor and reduction gear axles, potentiometer resolution, and gearing backlash. The equations of motion for the T-33 aircraft were simulated with the analog portion of a hybrid computer. (Author)
