Abstract
A gas turbine engine includes a bushing that is non-round in cross-section, the bushing receivable within an aperture. A fastener passes through the bushing to retain a second component to a third component with respect to the first component.
Claims20
An alignment system comprising:
- a bushing with a set of tabs;
- and
- a fastener with a threaded section, an interface section and a head, said head receivable between said set of tabs.
A gas turbine engine comprising:
- a first component with an aperture;
- a bushing that is non-round in cross-section, said bushing receivable within said aperture;
- and
- a fastener which passes through a bushing to retain a second component to a third component with respect to said first component, said third component with an elongated aperture greater in size than said aperture, said elongated aperture located within a recess.
1 more element
A method of alignment assessment of clearances between features that permit a limited rotation, comprising:
- quantifying a range of rotation of a clearance interaction as a numerical value by integrating tolerances that correspond to features that permit a limited rotation to obtain a rotational assessment;
- and
- applying the rotational assessment to a tolerance stack-up.
