Applying Controlled Pressure Distributions to Complex Curved Surfaces

A technique for applying controlled test pressures to curved surfaces is based on a principle similar to that of a compartmented pilot's or astronaut's pressure suit. The technique involves the use of airbags that accommodate geometric complexity in both the surface under test and in the spatial variation of the pressure to be applied. This method also provides the enhanced capability to vary the pressure locally, refining the load distribution at the airbag interfaces.
