An Investigation of the Dynamic Stability Characteristics of a Quad Configuration, Ducted-Propeller V/Stol Model. Volume IV. The Longitudinal Stability Characteristics of a Quad Configuration, Ducted-Propeller V/Stol Model at High Duct Incidence

Abstract

Data that pertain to the longitudinal dynamics of the vehicle at five duct incidences were analyzed to determine the stability derivatives of the vehicle. The analysis and the resulting stability derivatives are presented and discussed in this report. The measured time histories indicated that the data could be analyzed on the basis of linearized small perturbation equations. Root locus techniques were used to analyze the data. The full-scale derivatives determined from the analysis that correspond to a vehicle very similar to the Bell X-22A are presented.
