    <!-- taken from the lift curve figure -->
    <!-- alpha_0 is 5 degrees -->
    <!-- alpha_stall is 19.3 degrees -->
    <!-- slope of the lift curve to the left of the stall angle -->
    <!-- slope of the lift curve to the right of the stall angle -->

    <!-- below are just random values in this example -->
    <forward>-1 0 0</forward>
    <upward>0 -1 0</upward>
    <cp>0 0 1</cp>
