METHOD OF GAS TURBINE ENGINE CONTROL Russian patent published in 2009 - IPC F02C9/00 

FIELD: engines and pumps.

SUBSTANCE: invention is related to the field of aviation propulsion engineering and may be used in electronic-hydromechanical systems (SAU) for automatic control of gas turbine engine(GTE). Substance of invention consists in the fact that additionally in ER depending on engine control lever (RUD) and control system parameter values according to control laws realised in GMR, ER reserve control action is calculated, in case ER fails, possible consequences of failure for gas turbine engine and aircraft are analysed, if due to failure it becomes impossible to control engine according to control laws realised in ER, ER reserve control action is sent to IE, calculated according to control laws realised in GMR, if due to failure engine control from ER becomes totally impossible, with the help of selector ER control action is interrupted, and control action of GMR is supplied to IE and engine is controlled from GMR.

EFFECT: higher quality of SAU operation and accordingly higher reliability of gas turbine engine and aircraft safety.
