Abstract

See full text

Methods and systems for adjusting a modulation characteristic of a bleed-off valve of a gas turbine engine are described. The method comprises obtaining a first setpoint configuration associated with a first modulation characteristic of the bleed-off valve, obtaining operating conditions of the gas turbine engine, determining an adjustment factor based on the first setpoint configuration and the operating conditions of the gas turbine engine, and adjusting the bleed-off valve to a second setpoint configuration associated with a second modulation characteristic based on the first setpoint configuration and the adjustment factor, the second modulation characteristic being different from the first modulation characteristic.
