A Comparative Analysis of Tilt Rotor Aircraft versus Helicopters Using Simulator Results

Abstract

This thesis conducts a comparative analysis of the tilt rotor aircraft with conventional helicopters using simulator results from LHX- representative missions. Results regarding inter-aircraft differences using Ordinary Least Squares regression analysis are discussed. Also examined are single versus dual piloted airframe configurations, cockpit designs, varied background inter-pilot differences, those transitions from the helicopter to the tilt rotor causing the most difficulties, those flight missions causing the most operator overloads, and what automated features best help relieve these workloads. Pilot opinions from a questionnaire concerning these subjects are also presented. Results show the tilt rotor superior in hard, maximum effort turns and in firing at elevated and depressed targets, while the helicopter has the advantage in lateral movements and quick hover up/hover down maneuvers. The two-man cockpit configuration is notably safer with significantly less operator overloads. Pilot differences between communities were found to be negligible in this study.
