Abstract
Official abstract text for this publication.
A gas turbine engine includes a fan shaft and a support which supports the fan shaft. The support defines at least one of a support transverse and a support lateral stiffness. A gear system drives the fan shaft. A flexible support at least partially supports the gear system, and defines at least one of a flexible support transverse and a flexible support lateral stiffness with respect to at least one of the support transverse and the support lateral stiffness. An input to the gear system defines at least one of an input transverse and an input lateral stiffness with respect to at least one of the support transverse and the support lateral stiffness. A method of designing a gas turbine engine is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A gas turbine engine comprising: a fan shaft; at least one bearing that supports the fan shaft; a support configured to support at least a portion of the fan shaft, the support defining at least one of a support transverse stiffness and a support lateral stiffness; a gear system configured to drive the fan shaft; a flexible support configured to at least partially support the gear system, the flexible support defining at least one of a flexible suppo…
