Experimental Studies of the Effect of Rectangular-Shaped Canard on a Generic Blended Wing Body (BWB)

The purpose of this study is to investigate effects of canard on Universiti Teknologi Malaysia Blended Wing Body model (UTM-BWB). A model of generic blended wing body has been designed and fabricated locally in UTM. The experiment was conducted in Universiti Teknologi Malaysia Low Speed Wind Tunnel (UTM-LST) with maximum speed of 80 m/s. During the experiment, the model was mounted on the steady balance measurement equipment located underneath the wind tunnel. Two measurement techniques were employed on the wing, the first one was the turf thread to observe the flow separation above the wing while the second experiment was the steady balance measurement to obtain the aerodynamic characteristics of model. The experiment has been performed at the speed of 30 m/s in two phases. The first phase was the experiment without the canard while the second phase was the experiment with the canard. The canard has been designed with interchangeable angles of 0, 10, and −10°. The experiments were conducted at the angle of attack, α varies from −3 to 15° and sideslip angle, β from −8 to 8°. The Aerodynamic data obtained were plotted in order to obtain aerodynamic characteristics of the BWB model with and without canard configurations at certain angle of attack and sideslip angle.
