Embodiment Construction

[0059] One or more specific embodiments of the invention are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developer's specific goals (such as compliance with system-related and business-related constraints), These specific goals will vary from implementation to implementation. Furthermore, it should be appreciated that such a development attempt would be complex and time consuming, but would nonetheless be a routine undertaking of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure.

Abstract

The invention relates to a seal for turbo machine segments. In one embodiment, the seal having a first sealing end portion, a second sealing end portion, and an intermediate portion between the first and second sealing end portions, wherein the seal has at least one metering hole configured to control a leakage flow across the seal.

Description

technical field [0001] The subject matter disclosed in this specification relates to seals, and more particularly, to seals disposed between sections of a turbomachine. Background technique [0002] Various turbomachines (eg, turbines and compressors) may include seals disposed between segments. For example, a gas turbine may include stationary segments arranged circumferentially around a rotor, the gas turbine including turbine blades. Unfortunately, segments experience thermal expansion and contraction, vibration, bending, and other forces that reduce the effectiveness of the intermediate seal. In addition, the seals experience large pressure differentials between the different fluid flows (eg, the hot gas flow driving the turbine blades and the air flow cooling the segments). As a result, the seals can experience uncontrolled amounts of leakage, which can reduce the performance and reliability of turbomachinery (eg, gas turbines). Accordingly, there is a need for a sea...
