A Close-Coupled Canard, Technology Demonstration Aircraft for General Aviation Applications 871883

From the literature, theoretical analyses and subscale windtunnel aerodynamic investigations of canard aircraft configurations indicate benefits which are enhanced by close-coupling the canard to the wing. To properly evaluate the advantages and to investigate some solutions to the problems associated with the close-coupled canard, a full-scale aircraft development was initiated. A dual purpose of this development was to create a proof-of- concept vehicle designed to satisfy a general aviation requirement, and demonstrate a subsonic, close-coupled canard technology. This paper describes the development together with the aerodynamic considerations of the design. Ultimately, flight-test data are to be used in establishing correlations with windtunnel model data and analytical methodology.
