Louver systems (100,200,300) for gas turbine bleed air systems (40) are disclosed. An example louver system (100) may include a bleed system discharge opening (48) arranged to vent bleed air (2) from a bleed flow conduit (44) and a plurality of pivotable l...

Bleed air systems for use with aircrafts and related methods are disclosed. An example apparatus includes a turbo-compressor including a compressor having a compressor inlet fluidly coupled to a low-pressure compressor of the aircraft engine and a compress...

The method involves driving a rotor to a predetermined rotor speed, and carrying out combustion of a gaseous fuel within a stationary gas turbine. A hot driving gas is supplied to the rotor by the turbine. Compressor air is discharged into an exhaust chann...

A gas turbine engine (20) includes a low spool (3 8) along an engine axis with a forward fan section (22) and a low pressure turbine section (30). A high spool (40) along the engine axis has a high pressure turbine section (28) and an aft core driven fan s...

The exhaust gases (19) in an exhaust gas stream (21) of the gas turbine power plant are sent for recirculation into a suction flow of the gas turbine (6), and the exhaust gas stream (24) is discharged to the environment. A control element (29) is arranged ...

A bleed air power assist system is coupled to a gas turbine engine (100) that includes a high pressure turbine (126), a low pressure turbine (128), and an electrical generator (138) driven by the high pressure turbine (126). The bleed air power assist syst...
