The longitudinal characteristics of a multi cranked wing in tandem with a canard were investigated on a 2\% scaled generic, modular wind tunnel model in the 2.85m x 2.85m Open Jet Facility (OJF) at Delft University of Technology. The experimental campaign yielded force, moment and surface oil flow data for a moderate angle of attack range of –5 to +22 °, at a free stream velocity of 30 m/s, and at a Reynolds number of 0.5 million based on the wing mean aerodynamic chord. An experimental approach was followed to understand the complex aerodynamic characteristics of the multi cranked wing. The results presented in this thesis provide the low speed trends for a canard and multi cranked wing configuration, with emphasis on the canard and wing interactions. It provides insights on optimal longitudinal and vertical placement of the canard with respect to the multi-cranked wing for maximizing improvements with respect to lift, drag and longitudinal stability characteristics of the configuration. High fidelity aerodynamic database developed as part of this thesis can be used in the design of future fuel-efficient unconventional canard aircraft configuration(s).
