An aircraft anti-icing system includes a source of high temperature gas, a housing, at least one conduit to carry the high temperature gas from the source to the housing, the at least one conduit coupled to the housing and the source, at least one nozzle coupled to the at least one conduit, at least one nozzle configured to impart a rotational motion to the high temperature gas before exhausting the high temperature gas into the housing, and a port for exhausting air from the housing.

Method and apparatus for aircraft anti-icing

A method is provided for operating a gas turbine engine that includes a high pressure compressor and a water injection apparatus for injecting water into a flow of the engine upstream from the high pressure compressor. The method includes the steps of operating the engine without injecting water into the gas flow of the engine, injecting water at a first flow rate into the gas flow for power augmentation once engine full power is about reached, and injecting water into the engine at an increased second flow rate for evaporative cooling of engine components downstream from the high pressure compressor.

Methods for operating gas turbine engines

A heat shield mechanism for thermally protecting a casing located in a turbine engine having a plurality of honeycomb cells which are connected to a support plate. A spring in contact with the support plate and in contact with a vane liner exerts a force on the support plate which causes at least one of the plurality of honeycomb cells to be pressed against the casing.

Heat shield for a compressor/stator structure

A stator vane liner assembly includes seal keys supported in slots in the ends of vane liner segments in an engine casing. Stationary vanes supported in the liner segments for directing an engine airflow are urged against the keys by the engine airflow gas loads. The seal keys engage the ends of adjacent vane liners for sealing, and prevent further motion of the vanes with respect to the liner segments due to the engine airflow gas loads. Secondary seal means can be slidably captured between the seal key and vane liner segment to prevent axial and radial leakage around the seal key. The liner assembly reduces leakage of engine airflow and helps to isolate the engine casing from the thermal effects of leakage of engine airflow.
