WAY AND ADJUSTMENT ELEMENT OF THE TARGET VALUE OF THE PARAMETER THAT AFFECT ON GAS-TURBINE ENGINE DRAFT Russian patent published in 2017 - IPC F02C9/28 

FIELD: engines and pumps.

SUBSTANCE: there is a way of target value adjustment of at least one parameter that affect on a draft of a gas-turbine engine that sets in motion an air vehicle during the air vehicle flight stage. It comprises: a stage at which one obtains a current value of at least one engine target variable, a stage at which one derives a decrement value for the at least one noted parameter from the predetermined table; the noted parameter is connected with the current value of at a minimum one mentioned engine target variable. The method also comprises a stage at which one regulates target value of at least one noted parameter by virtue of applying the decrement value to this parameter. The decrement value is derived from the table. Besides, the appliance for the gas-turbine engine draft control is presented. It sets in motion an air vehicle during the flight stage. The appliance also regulates the target value for at least one parameter that affect on the noted draft which is regulated with the aid of the claimed adjustment method.

EFFECT: invention allows to reduce the air vehicle draft by simultaneous numerous target values adjustment without being limited to one particular engine type.
