Effect of end plates on the surface pressure distribution of a given cambered airfoil: experimental study
Wind tunnel experiments were carried out on a GA(W)-2 airfoil and surface pressures were measured at constant free stream speed of 30 m/sec by varying the end-plates shapes at discrete angle of attack (-10 0 to 30 0 ). These selected varied shaped end-plates had a significant affect on the aerodynamic characteristics for a given airfoil along with considerable variations in the flow phenomena involving flow separation, tip and blockage effects. These were experimentally investigated and analyzed to attain the controlled 2-D configurations thus provides an on-hand data for calculating the non-dimensional parameters indulged in the performance of varied applications involving airfoils. Present study indicates that endplate C gives the closest two-dimensional configuration. Lift curve slope increases and stall angle decreases as the end plate size increases from A to C.
