FIELD: engines and pumps.
SUBSTANCE: invention can be used in electronic hydro mechanical automatic control systems (ACS) of gas turbine engines (GTE). At operation on ER (electronic regulator) the level of high-energy γ-emission is controlled by means of warning device; when the latter is actuated, ER electric power supply is switched off; control of engine is switched over to HMR (hydro mechanical regulator) and hydro locking device of temporary type (HLDTT) is actuated and the time of rerun of which from stop to stop is certainly larger than time of action of high-energy γ-emission at nuclear explosion; HLDTT rerun is fixed by means of limit switch, electric power supply of ER is switched on, tested as per programmes stored in read-only memory (ROM), and in case ER is operable, engine control is switched over to ER.
EFFECT: improving operating quality of ACS, and improving GTE reliability and aircraft safety.
