The present invention relates to a device for controlling the speed of the engines of an aircraft. According to the invention, the mechanical transmission (8) between the servomotor (6) and the throttle lever (4) comprises a coupling which can be overridden by the deliberate action of the hand of the pilot on the throttle lever (4), and the computer (18) comparing the speed to be reached X OBJ and the limit speed of the engine X LIM and supplying a signal which is representative of the datum speed of the engine X CONS, is linked to a computer (28), linked to the computer (22) supplying a signal which is representative of the speed of the engine corresponding to the position of the throttle lever X(TLA), said computer (28) supplying, from signals from the computers (18) and (22), a signal which is representative of the demanded speed of the engine X COM, such that: if the relation X(TLA)-DX CONS≤X (TLA)+D1) (where DX COM=X(TLA)-DX CONS(TLA)-DX COM=X(TLA)+DX CONS(TLA)+D

A device for controlling the speed of an aircraft engine, said engine of an aircraft comprising a control device, and able to be manipulated by a pilot, of the type comprising: a throttle lever (4) linked, on the one hand, to a sensor (5) of the position of the latter and, on the other hand, to a se
A device for controlling the speed of an aircraft engine, said engine of an aircraft comprising a control device, and able to be manipulated by a pilot, of the type comprising: a throttle lever (4) linked, on the one hand, to a sensor (5) of the position of the latter and, on the other hand, to a servomotor (6) provided with a control (7), by means of a mechanical transmission (8), said control device (3), allowing the pilot to choose the flight mode, being linked, on the one hand, to a first computer (9) intended to calculate the speed of the engine to be reached X OBJ and, on the other hand, to switchover means (11) with two positions, one corresponding to manual control and the other to automatic control, and comprising two inputs, “manual”(11A) and “automatic”(11B), said first computer (9) further receiving information relating to parameters external to the engine, and delivering a first signal which is representative of the speed of the engine to be reached X OBJ, to the input of a second computer (18), comparing said speed to be reached X OBJ and the limit speed of the engine X LIM, and delivering, at its output, a second signal which is representative of the datum speed of the engine X CONS, such that: 1) if X OBJ2) if X OBJ≥X LIM then X CONS=X LIM, said position sensor (5) being linked to the input of a third computer (22), supplying at its output a third signal which is representative of the speed of the engine corresponding to the position of the throttle lever X(TLA), and linked to the “manual”input (11A) of said switchover means (11), said second and third signals being supplied to the inputs of a comparator (26) whose output is linked to the control (7) of the servomotor (6), and the second computer (18) being linked to the “automatic”(11B) input of said switchover means (11), wherein the mechanical transmission (8) between the servomotor (6) and the throttle lever (4) comprises a coupling which can be overridden by the deliberate action of the hand of the pilot on the throttle lever (4), and wherein the second computer (18) is linked to the switchover means (11) by means of a fourth computer (28) linked, furthermore, to the third computer (22) and supplying, from the second and third signals, a fourth signal which is representative of the demanded speed of the engine X COM, such that: a) if the relation X(TLA)-DX CONS≤X (TLA)+D1) (where D1) is not satisfied, then X COM=X(TLA)-DX CONS(TLA)-DX COM=X(TLA)+DX CONS(TLA)+D
