초록

An exemplary embodiment of the invention is a spinner for a front end of a fan assembly of a gas turbine engine. The spinner includes a single piece substantially conically shaped hollow body circumscribed about a centerline extending aftwardly from a tip to an axially aft spinner end. A plurality of bolt holes extend axially parallel to the centerline through the hollow body at an axial location between the tip and the aft spinner end. The hollow body may include a forward conical section extending aftwardly from the tip to a transition section, an aft ...
