As such, four roof modules with fully operational flaps corresponding to each right-hand flap angle
were constructed and installed on the NASCAR lift-off test vehicle.
In automatic mode, operators set the flap angle
and glue gap the first time; all other measurements are set automatically.
3) Because the Dufourmental modification employs a larger flap angle
and shorter arc of rotation, like the Webster modification, it results in more sharing of tension between the primary and secondary defects.
Thus, the essential features for airfoil's aerodynamics, in a 2-D framework, are described by a quasi-steady model for the lift, pitching moment and hinge moment; an aggregate aeroservoelastic model having three degrees of freedom (the plunge h, the pitch a and the flap angle
[beta]) is so obtained.
