    Lift of an Aircraft's Wing - An Explanation

    I have been disappointed by most explanations of a wing's lift. It is not caused by the higher velocity over the top surface. Try applying an estimated velocity and see what is necessary to reflect the observed pressures. It does not work. My explanation of a wing's lift is based on the...

    Caveats of high lift airfoil

    CAUTION! To anyone considering a flying a surface close to or on a restricting surface (WIG).

However, the air velocity is...

    PSRU

    PSRU Components For a cog belt PRSU, you might try contacting Goodyear or Gates about their products. I think they both have cog belts and pulleys. However, they may not approve or support use of their belts for aircraft power transmision.
