An Experimental Investigation of the Aerodynamic Characteristics of Nose Mounted Canard Configurations at Supersonic Mach Numbers (1.5through 4.5).

摘要

Experimental aerodynamic investigations were conducted in a supersonic wind tunnel to determine the aerodynamic characteristics of several nose mounted canard wing configurations. Canard position,geometry,angular orientation,and model nose shape were varied systematically to determine their effects on model aerodynamics. The model was tested at angles of attack of -5to 13degrees and Mach numbers of 1.5to 4.5. Aerodynamic loads were measured separately on four canards and tail panels,and the total model. The vapor screen method was used to trace the paths of the vortices shed from the canards. Roll control effectiveness of canards,both with a planar tail and a ring tail was investigated.
