Patent ID: 6921244

Claim:
A system for controlling the operation of gas turbine engine bleed valves, comprising: first equipment adapted to sense the pressure of a gas turbine engine and to produce and send electronic signals representative the pressure of the gas turbine engine; a control device adapted to receive and process the electronic pressure signals, and to output control signals responsive to the electronic pressure signals; and second equipment adapted to receive the control signals from the control device and to control operation of at least one bleed valve within the engine, the second equipment including: a control valve manifold in communication a programmable logic device and adapted to receive the additional signals from the programmable logic device, wherein the control valve manifold is in communication with an air source and includes at least one solenoid valve, and wherein the programmable logic device provides signals to the control valve manifold to control the opening and closing of the at least one solenoid valve such that at least some of the air supplied to the at least one solenoid valve by the air source will flow through the at least one solenoid valve when the at least one solenoid valve is open.
