Lift, Drag, Normal, and Axial Forces on a Flat Plate

  1. Sep 5, 2011 #1
    1. The problem statement, all variables and given/known data
    Consider an infinite thin flat plate with a 1m chord at an angle of attack of 10 degrees in a super sonic flow. Describe the angle theta between the Lift and Normal Force, is it the same as the Drag and Axial?


    2. Relevant equations
    L=Ncos(a)-Asin(a)
    D=Nsin(a)+Acos(a)


    3. The attempt at a solution
    I thought the theta would be alpha (angle of attack) but since we have a flat plate I know that something is going to be different. I emailed my prof and he mentioned that it is going to be some constant directly related to geometry.
