“…The interactions between canard and other elements are also hard to predict well in initial design. Although some corrected theoretical and semi-empirical methods developed by previous studies [4][5][6][7] can successfully predict canard-wing and canard-body interaction effect on static aerodynamic force and moment increment for some axisymmetric canard configurations, it has difficulty in expanding to predict some nonaxisymmetric configurations and has to depend on specific experiment data at some speeds. Those methods also fail to predict the stability and control characteristics variation well when canard reflects, which is very important to the control system design.…”

This paper presents an aerodynamic study for a target unmanned air vehicle with controlled canard, at cruise Mach number between 0.7 and 0.85, using a solid rocket motor as power. The results of semi-empirical method (DATCOM), computational fluid dynamics (CFD) were compared with wind tunnel tests to evaluate perdition accuracy. Here DATCOM shows big discrepancy in pitching-moment coefficient; the CFD estimation of static aerodynamic force and moment agree well with wind tunnel data. An analysis was focused on the longitudinal data for complicated controlled canard-elements interactions and canard vortex behavior. The canard vortex interaction with tail wing of initial configuration concept with a thick canard (NACA0012) and the final improved configuration with a thin canard (NACA0007) were reviewed. It is proved that the stability and control characteristics of whole TUAV are sensitive to the thickness of canard in transonic peed regime because of different canard vortex intensity and effect generated.

An aerodynamic study is presented for controlled canard configuration of a target unmanned air vehicle (TUAV) at cruise Mach number between 0.7 and 0.85, using a solid rocket motor as power. The analysis was focused on the longitudinal wind tunnel test data for learning complicated controlled canard-elements interactions and canard vortex behavior. The canard vortex interaction with tail wing of initial configuration concept with a NACA0012 canard and the improved configuration with a NACA0007 canard were reviewed and discussed. The experiments prove that the stability and control characteristics of whole TUAV are sensitive to the thickness of canard in transonic peed regime because of different canard vortex intensity and effect generated. The flight experiment shows that the final improved controlled canard configuration satisfies the request of the control system.
