  • Integrated bleed load compressor and turbine control system
    Patent number: 5117625
    Abstract: Unstable operation of a gas turbine engine subject to variable shaft loading and bleed air loading may be avoided in a gas turbine (12, 22, 40) having first and second stage compressors (12, 22) on a common shaft (10) with a turbine wheel (40) and by providing the inlet (14) to the first stage compressor (12) with variable inlet guide vanes (16). Bleed air flow is controlled by a bleed air valve (60) connected to the interface (24) of the first stage compressor outlet (18) and the second stage compressor inlet (20). A controller (66) is operative to control the position of the inlet guide vane (16) in response to bleed air flow sensed by a sensor (58).
