FORCES AND MOMENTS ON A FLAPPED WING
|

|
... Several curves were plotted using the results and it was concluded that the cambering of the wing produced greater CL for a given a. ... Flaps are high lift devices which are located on the trailing edge of the wing. ... When extended, it increases the camber of the wing, and the angle of the attack. ... A wing will stall when the airstream doesnt have sufficient energy to make the required change in direction to follow the camber of the wing. ... The aerodynamic forces on the wing will also result in pitching moments about the centre of gravity, which will vary with flap deflection as well as the amount of flap deflection. ...
The model we used consisted of a cambered wing of aspect ratio 5 (span 0. ... The wing was mounted upside down at quarter wing to avoid disturbance of the aerodynamic flow. ... For a given angle of attack, the lift force became higher as η increased, since the camber of the wing increased. ... 1mm from leading edge for this wing).
To check if reliable results were attained, after recording the lift and pitching moments for the a range, we pitched the aerofoil down to an previously used a, and checked if the same readings were again obtained. ... By attaching a plain flap to the trailing edge, higher lift can be achieved be for a given a, enabling low speed flying and also reducing the stalling speed of the wing. ...
The aerodynamic centre of the wing was calculated to be 30.
