Aerodynamics ( flap question)
Hello everybody I have a question on flap deflection
What I understand is when we lower the flaps ,It changes the camber of the aerofoil and this cause an increases both lift and drag.
Now more lift means more induced drag , With more induced drag wingtip vortices formation will be more. And also downwash also increases when we deflect flaps downwards.
Now what I know is if we have more wingtip vortices and downwash on the wing , it reduces effective angle of attack and to generate the same amount of lift you need to increase angle of attack , the same case happens when we take off and comes out of ground effect.
sir now the question is that with flaps lowered your Clmax of the aerofoil increases but your stalling angle decreases.
If the effective angle of attack of the wing decreases don't we get more range of angle of attack , as the particular aerofoil will always stall on the critical angle of attack?
Please somebody explain me where I am going wrong in understanding the concept
Thanks
