ABSTRACT:
An apparatus for applying non-gravitational pressure to a surface includes a frame structure having a longitudinal axis, a pair of connecting members coupled to the frame structure along parallel axes normal to the longitudinal axis of the frame structure, vacuum fasteners coupled to the connecting members to secure the frame structure on an underlying surface, a vacuum pump mounted on the frame structure for activating the vacuum fasteners and a positive pressure pump mounted on the frame structure for inflating a collapsible diaphragm to apply pressure to the underlying surface. The apparatus is useful for applying doublers to aircraft components to repair localized damage.
