Abstract
A component for a gas turbine engine includes a component body formed of ceramic matrix composite lamina and has at least one hook. The at least one hook has an attachment region radially inward of the at least one hook. The attachment region is radially thinner from a hook end of the at least one hook to a remote end, and then becomes radially thicker. A slot is formed through a radial thickness of the at least one hook from the hook end in a remote direction, such that there are two sections of the attachment region. A gas turbine engine is also disclosed.
Claims15
A gas turbine engine comprising:
- at least one turbine blade, and a blade outer air seal mounted radially outwardly of said at least one turbine blade;
- the blade outer air seal formed of ceramic matrix composite lamina and having at least one seal hook, said at least one seal hook having an attachment region on a radially inward portion of said at least one seal hook, said attachment region being radially thinner from a hook end of said at least one seal hook to a remote end, and then becoming radially thicker;
- a slot formed through a radial thickness of said at least one hook from said hook end in a remote direction, such that there are two sections of said attachment region;
- wherein there are at least two of said at least one seal hook each formed with a distinct one of said attachment region and a distinct one of said slot;
- and
- the blade outer air seal being attached to a static structure through a mount member, said mount member having at least two mount hooks each received in a space under one of said at least two seal hooks, with each said mount hook contacting one of said attachment regions, and spanning said slot.
A component for a gas turbine engine comprising:
- a component body formed of ceramic matrix composite lamina and having at least one seal hook, said at least one seal hook having an attachment region radially inward of said at least one seal hook, said attachment region being radially thinner from a hook end of said at least one seal hook to a remote end, and then becoming radially thicker;
- a slot formed through a radial thickness of said at least one seal hook from said hook end in a remote direction, such that there are two sections of said attachment region;
- and
- wherein said at least one seal hook has a vertical portion downstream of an end of said slot extending vertically to connect into a base of said component body, and said slot not extending entirely through said vertical portion to the base.
