Abstract
Система управления потоком воздуха, который вводится в оболочку газовой турбины авиационного двигателя, причем поток воздух регулируется регулировочным вентилем (60), положение которого определено первым управляющим сигналом (SC10), вычисленным на основе первого заданного значения (VC10), которое соответствует заранее определенной величине зазора между ротором и оболочкой турбины. Система дополнительно содержит средства (20; 30) вычисления, по меньшей мере, одного второго управляющего сигнала (SC20; SC30) на основе второго заданного значения (VC20; VC30), которое отличается от первого заданного значения (VC10), соответствующего величине зазора в турбине, и средства (50), предназначенные для выбора второго управляющего сигнала для управления регулирующим вентилем в зависимости от значений, по меньшей мере, одного параметра двигателя. Данная система дает возможность осуществлять управление потоком воздуха, который вводится в оболочку, соответственно нескольким логическим схемам.
