Abstract

The present invention provides a balloon assembly and related hole alignment systems and methods. The bladder assembly (10) includes an inflatable bladder (12) comprising an elongated body (30) defining an interior volume (31), the body (30) being formed into a layered structure (50), The layered structure (50) includes an elastomeric layer (52) defining an inner surface (58) of the body, a friction reducing layer (56) defining an outer surface (60) of the body (30), and an a jacket layer (54) between said elastomeric layer (52) and said friction-reducing layer (56); and a source of pressurized fluid (14) selected from said internal volume (31) in fluid communication.

Description

technical field [0001] This application relates to hole alignment devices, and more particularly, to the use of inflatable bladders to achieve alignment of more than two holes. Background technique [0002] Mechanical fasteners such as pins, rivets, bolts, etc. have long been used to connect one member to more than one other member. In a typical example, a first hole formed in the first member is aligned with a second hole formed in the second member. A mechanical fastener (eg, a pin) is then inserted through the two holes, thereby inhibiting displacement of the first member relative to the second member. A securing feature such as a nut or cotter pin may engage the mechanical fastener to inhibit accidental removal of the mechanical fastener from the hole. [0003] Various aircraft components are joined together by means of mechanical fasteners. For example, the wings of an aircraft may be secured to the fuselage by means of mechanical fasteners such as bolts. Unfortunat...
