ABSTRACT:
A novel test fixture for simulating aerodynamic loading on an airfoil is described which comprises a pair of arrays of a plurality of individual pressure controlled flexible bellows supported between a pair of platens, one array configured to contact and conform to the upper surface of the airfoil and simulate the partial vacuum distribution thereacross, the second array configured to contact and conform to the lower surface of the airfoil and simulate the pressure distribution thereacross. A compliant stabilization structure configured to provide lateral stability to the bellows arrays under pressure conditions is described.
