초록 ▼

A system for starting a gas turbine engine of an aircraft is provided. The system includes a pneumatic starter motor, a discrete starter valve switchable between an on-state and an off-state, and a controller operable to perform a starting sequence for the gas turbine engine. The starting sequence includes alternating on and off commands to an electromechanical device coupled to the discrete starter valve to achieve a partially open position of the discrete starter valve to control a flow from a starter air supply to the pneumatic starter motor to drive rotation of a starting spool of the gas turbine engine below an engine idle speed.

1. A system for starting a gas turbine engine of an aircraft, the system comprising: a pneumatic starter motor;a discrete starter valve switchable between an on-state and an off-state;a controller operable to perform a starting sequence for the gas turbine engine, the starting sequence comprising alternating on and off commands to an electromechanical device coupled to the discrete starter valve to achieve a partially open position of the discrete starter valve to control a flow from a starter air supply to the pneumatic starter motor to drive rotation of a starting spool of the gas turbine engine below an engine idle speed;an electronic engine control system comprising:a memory for recording a current heat state of the gas turbine engine at shutdown and for recording a shutdown time of the gas turbine engine; anda risk model for determining a time period (tmotoring) for motoring the gas turbine engine at a predetermined speed Ntarget wherein the predetermined speed is less than a speed used to start the gas turbine engine and wherein tmotoring is a function of the heat state recorded at engine shutdown and an elapsed time of an engine start request relative to the previous shutdown time. 2. The system as in claim 1, wherein the electromechanical device has a cycle time defined between an off-command to an on-command to the off-command that is at most half of a movement time for the discrete starter valve to transition from fully closed to fully open. 3. The system as in claim 1, wherein the electromechanical device is a solenoid that positions the discrete starter valve based on intermittently supplied electric power. 4. The system as in claim 1, wherein the electromechanical device is an electric valve controlling muscle air to adjust the position of the discrete starter valve. 5. The system as in claim 1, wherein the controller modulates the on and off commands to the electromechanical device to further open the discrete starter valve and increase a rotational speed of the starting spool. 6. The system as in claim 1, wherein the time period (tmotoring) is calculated automatically during a start of the gas turbine engine. 7. The system as in claim 1, wherein the controller modulates a duty cycle of the discrete starter valve via pulse width modulation. 8. The system as in claim 1, wherein the predetermined speed Ntarget is within a predetermined speed range NtargetMin to NtargetMax that is used regardless of the calculated time period tmotoring.
