Abstract
Official abstract text for this publication.
A turbine engine shutdown temperature control system configured to foster consistent air temperature within cavities surrounding compressor and turbine blade assemblies to eliminate turbine and compressor blade tip rub during warm restarts of gas turbine engines is disclosed. The turbine engine shutdown temperature control system may include one or more casing temperature control housings extending along an inner surface of a casing at an outer diameter of the casing and at an upper side region of the casing. The upper side region may be positioned above a horizontally extending centerline of the casing. Fluids may be exhausted from one or more exhaust slots in the casing temperature control housing to isolate the upper side region of the casing from buoyancy effects of hot gases within the casing after shutdown of the gas turbine engine.
First claim
Opening claim text (preview).
I claim: 1. A turbine engine shutdown temperature control system for a gas turbine engine, comprising: a casing forming an outer structure surrounding at least one turbine component, the casing a first half coupled to a second half, the first and second halves of the casing being positioned on opposite sides of a centerline of the casing; one or more casing temperature control housings extending along an inner surface of the casing and at an upper side region of the casing, wher…
