FIELD: aviation.
SUBSTANCE: group of inventions relates to a device and method for controlling an auxiliary engine, a multi-engined aircraft structure, a helicopter comprising such a structure. Auxiliary engine control device contains gas generator, free turbine, proportional-integral controller made with possibility to receive signal characterizing error rate of free turbine of auxiliary engine. To implement the method, a signal characterizing the auxiliary turbine free turbine speed error is received, method includes generating a signal for correcting the speed of rotation of the auxiliary engine gas generator in a certain manner. Structure of multi-engine helicopter comprises power plant and auxiliary engine, auxiliary engine control device.
EFFECT: enabling control of auxiliary engine depending on main engines.
