Abstract

The paper presents a numerical simulation of an automatic go-around of an aircraft with a failed engine. When an engine fails, it reveals additional resistance force as well as entails unbalanced forces and moments at a roll and a yaw rotation. To quantify an automatic go-around of an aircraft with a failed engine, the value of the steady climb full gradient should not be lower than its minimum set point. Thus, for a four-engine airplane the minimum set value of the full steady climb makes up 2.7 %.

An automatic go-around of an aircraft with a failed engine (with no regard to the failure compensation) is characterized by a decreased full gradient of the steady climb and the current gradient as well as a “sluggish” acceleration of the aircraft speed and climb.

The synthesis of the law of automatic compensation for a failed engine is based on the principle of direct measurement of disturbances and their application in a loop control of the rudder. The measured disturbances typical of an engine failure include deviation of the set rotor speed of low-pressure fans for the left and right engines as well as a lateral acceleration in the direction of the failed engine.

The devised law of automatic compensation for a failed engine in the rudder channel allows to increase the supply of a complete steady gradient of an aircraft climb by 2.0-3.0 % and improve the dynamics of velocity acceleration and the aircraft climb.
