Abstract:

The results of experiments to determine the longitudinal dynamic stability characteristics of a quad configuration, ducted-propeller VSTOL aircraft at four low-speedhigh-duct-incidence trim conditions i sub d 80, 70, 60, and 50 deg are presented. Longitudinal transient responses in various degrees of freedom were measured using a dynamic model on the Princeton Dynamic Model Track. The data presented include time histories of the model motions in various longitudinal degrees of freedom that occur when the model is disturbed from trimmed flight. Responses are presented both with and without pitch rate feedback. The dynamic model employed in these experiments is a generalized research model arranged to represent closely the X-22A VSTOL aircraft.
