ENGINE BLEED POWER RECOVERY SYSTEMS AND RELATED METHODS

Engine bleed air power recovery systems (202) and related methods are disclosed. An example power recovery system (202) for an aircraft engine (110) includes a power recovery turbine (250) coupled to a shaft-driven device (204). A bleed air valve (534, 536, 538) coupled between the power recovery turbine (250) and a bleed air source (242, 244). A controller (500) configured to operate the bleed air valve (534, 536, 538) to allow bleed air to flow to the power recovery turbine (250) when the aircraft engine (110) operates in a predetermined mode of operation.
