Abstract
The wheel assembly hinged heat shield (10) comprises a plurality of arcuate sectors (12) which are attached firmly to one another by hinge mechanism (14). Each hinge mechanism (14) comprises arcuate shaped hinge members (18, 20, 22) of adjoining arcuate sectors (12) which receive therethrough an axial pin (24). The axial pin (24) has a cotter key (28) engaged therewith in order to capture axially the pin (24). The heat shield (10) is disposed within an aircraft wheel (30) such that when attachment mechanisms (37) are tightened to secure each arcuate sector (12) firmly to the wheel (30), the adjoining arcuate sectors (12) are each pulled circumferentially away from adjoining arcuate sectors (12) in order to effect a chordal tensioning therebetween. The chordal tensioning defines the critical radial positioning of sector interface regions comprising the hinge mechanism (14).
