Embodiment Construction

[0107] In the following specification and claims, reference will be made to a certain number of terms, which shall be defined to have the following meanings.

[0108] The singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise.

[0109] "Optional" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event occurs and instances where it does not.

[0110] Approximate language, as used herein throughout the specification and claims, may be applied to modify any quantitative expression that can be permissibly changed without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms such as "about", "approximately" and "approximately" is not to be limited to the precise value specified. In at least some cases, the approximate language may correspond to the precision of the in...

Abstract

A composite blade assembly and a method of assembling a composite blade are provided. The composite blade assembly includes a composite blade having a radially inner root. A composite blade assembly includes a first platform and a circumferentially adjacent second platform abutting the first platform at a platform joint. Each of the first platform and the second platform includes a radially outer surface and a radially inwardly extending attachment member. The platform joint includes a slot extending through adjacent edges of the first platform and the second platform. The slot is configured to receive the radially inner root and the radially inner root is configured to be sandwiched between the attachment members. The blade assembly includes an adhesive system configured to join the radially inner root of the composite blade and the attachment members into a unitary structure, and a retaining clip configured to bias the attachment members towards each other.

Description

technical field [0001] The field of the present disclosure relates generally to gas turbine engines, and more specifically, to methods and systems for strengthening bonded joints in rotatable components of blades. Background technique [0002] At least some known gas turbine engines use composite materials, for example, in compressor blades. In many respects, composite materials are superior to conventional materials used in gas turbine engines. In many applications, they are at least as strong as conventional materials, and the weight savings achieved when using composite components make their use very attractive. However, in various applications, the properties of composite materials alone may be insufficient. For example, foreign debris entering the core engine inlet will encounter the blades of the booster compressor or high pressure compressor. Such events typically cause damage to the compressor's blades. In some cases, portions of the blade may be separated from o...
