Spring loaded compliant seal for high temperature use

A component of a gas turbine engine exposed to a high temperature during operation of the gas turbine engine, the component comprising:

• a first seal slot;
• a second seal slot opposed to the first seal slot and forming a gap between the two seal slots;
• the two seal slots having a large misalignment from exposure to the high temperature during engine operation such that a rigid seal will not maintain an sufficient seal between the two seal slots;
• a flexible seal secured within the two seal slots;
• the flexible seal having a first outward curved seal half and a second outward curved seal half;
• the two outward curved seal halves form four seal contact surfaces to make contact with four surfaces of the two seal slots;
• and,
• a spacer positioned between the first and second outward curved seal halves.

A turbine stator vane for a turbine in a gas turbine engine, the stator vane comprising:

• a shell having an airfoil shape with a leading edge and a trailing edge and with a pressure side wall and a suction side wall extending between the leading and trailing edges;
• an insert secured within the shell;
• two opposed radially extending seal slots formed in the shell and the insert;
• an X-shaped flexible seal secured within the opposed seal slots;
• the X-shaped flexible seal having four ends that form contact surfaces with four surfaces of the two opposed seal slots;
• and,
• a spacer positioned between the first and second outward curved seal halves.
