A system (20) for a gas turbine engine includes a flowpath wall (30, 32) and a deflector (78). The flowpath wall (30, 32) includes a surface (56) and an opening (72) to a blind aperture (68). The surface (56) forms a peripheral boundary of an internal engi...

A statorless axial turbine for a turbocharger has a turbine housing assembly defining a meridionally divided scroll extending circumferentially and surrounding the turbine wheel, the meridionally divided scroll defining a first scroll extending substantial...

Provided is a turbocharger that compresses combustion air in an internal combustion engine and that force-feeds the high-density air into a combustion chamber of the internal combustion engine. The turbocharger includes a turbine rotor blade that is rotati...

A gas turbine engine (20) includes a flow control mechanism (60) operable to direct at least a portion of a fan airflow from a secondary flow path (56) into a core flow path (58).

A power extraction system (200) is disclosed having a forward fan stage (52) configured to pressurize an airflow (1), an aft fan stage (60) having a tip-fan (70) configured to pressurize a first portion (3) of a pressurized air flow (2) from the forward fa...
