Simulation of Helicopter and V/STOL Aircraft, Volume 6, XC-142 Analog Computer Program Study: XC-142A Simulation Equation Mechanization

The report presents the analysis and simplification procedures that are required to define and program the mathematical model for the XC-142A aircraft in a form which is suitable for mechanization and solution on a general purpose analog computer. This program will enable the Naval Training Device Center to perform dynamic simulation studies for a V/Stol tilt-wing aircraft. Section II contains the complete mathematical model of the XC-142 with accompanying denotation and validation. In Section III, three sets of simulation equations are presented. These sets represent the complete six degrees of freedom equations, longitudinal mode equations, and lateral-directional mode equations. Section IV contains the mechanization functional block diagrams along with the patching and operating instructions required for their utilization. Section IV also specifies the analog computer installation which is required to solve the mechanizations. The subsequent sections contain: a discussion of program limitations, conclusions, and recommendations.
