Control of thrust parameters of twin-shaft turbojet engines with their thrust asymmetry

Novichkov V. M., Burova A. YU.

The questions connected with the solution of problems of correction of asymmetry of thrust of turbojet engines of power plant of the twin-engine plane by software and hardware of electronic blocks of control system of its power plant in flight are considered.

A series of frequent recent aviation accidents of medium-haul and long-haul aircraft due to the asymmetry of the thrust of their engines during takeoff or landing actualized the solution of these problems to improve the algorithms of software and hardware of the automatic control system of the power plant of a twin-engine aircraft with turbojet engines. As thrust parameters of such engines, it is proposed to use the rotor speed of low-pressure compressors of its engines and the rotor speed of high-pressure compressors of the same engines. Automatic control of these thrust parameters according to the proposed algorithm of their control allows to reduce the asymmetry of the thrust of the two-shaft turbojet propulsion system of a twin-engine aircraft by equalizing the rotor speeds of low-pressure compressors and equalizing the rotor speeds of high-pressure compressors of its engines. The proposed algorithm of control of thrust-shaft turbojet engine power plant of twin-engine aircraft provides the opportunity to enhance their traction on the results of a comparative assessment of the relative rotor speeds low pressure compressors and comparative evaluation of the ratio of frequencies of rotation of the rotors of the high-pressure compressor with respect to the first derivatives of these frequencies. The practical implementation of the proposed algorithm in the software and hardware of the automatic control system of the power plant of a twin-engine aircraft with twin-shaft turbojet engines will provide an additional opportunity to reduce the asymmetry of their thrust in flight and the corresponding increase in flight safety. Such a solution to one of the problems of correcting the asymmetry of thrust of these engines on the basis of the proposed algorithm for controlling the parameters of their thrust can be considered a further development of the idea of reducing the asymmetry of thrust of the same type of turbojet engines in terms of their serial production at the factory and operation on mainline aircraft.
