    Hello every friends..:(
    I'm a student, at recently, i've research some theories for my study ('bout Air Cushion Vehicle ) without experimental practical.
    And i want to design a hovercraft with Finger skirt or Segment skirt.
    But i dont know what theory use for them.
    While I've learned some theories such as: Peripheral Jet , Plenum chamber, AA.West, Flow Rate coefficient

    Please help me.:confused:

    See Post 3 in the thread P2D: A Simple 2D-Planing Program
    http://www.boatdesign.net/forums/design-software/p2d-simple-2d-planing-program-41896.html and some of the replies.

    Search for papers by Lawrence J. Doctors who has been developing a
    method based on planing and how the skirts flex and change shape.
    I am not entirely convinced by the theory/method because it omits
    splash drag, but I might be wrong to think it is important.

    There is also a small program to calculate wave resistance and wave
    patterns of hovercraft in the thread "FLOTILLA: Hovercraft Hydrodynamics"

    Good luck with your studies!
