Effect of canards on delta wing vortex breakdown during dynamic pitching

Wichita State University's 2 x 3 ft water tunnel was used to analyze the effect of a canard on delta wing vortices. Delta-shaped wing-generated leading-edge vortices improves aircraft performance at high angles of attack. Results indicate that canard and dynamic pitch motion delays vortex breakdown. However, locating canards close to the main delta wing resulted in favorable delays.
