Experimental investigation of center elevator deflection on aerodynamics of UiTM's Baseline-I Blended Wing Body (BWB) unmanned aerial vehicle (UAV)

This paper describes the wind tunnel testing of a Blended Wing Body (BWB)-Baseline I with elevator developed in Universiti Teknologi MARA (UiTM). The experiment work was carried out in UiTM low speed wind tunnel using 1∶7 scaled model of BWB at Mach 0.1. The testing is conducted for center elevator angle between −10° to +10° until stall angle. The result show similar trends with zero elevator deflection case in terms of lift curve, drag curve and pitching moment curves.
