System and method for realizing engine automatic takeoff thrust control function

Abstract

The invention relates to a system for realizing an engine automatic takeoff thrust control function. The system comprises a first engine full authority digital engine control (FADEC), a second engineFADEC and an avionics system electrically connected with the first engine FADEC and the second engine FADEC, wherein the first engine FADEC and the second engine FADEC separately send ATTCS trigger input values to the avionics system, the avionics system performs ATTCS trigger logical judgment based on the ATTCS trigger input values to trigger the ATTCS, and sends an instruction of adjusting engine thrust to the first engine FADEC or the second engine FADEC. The invention further relates to a method for realizing the engine automatic takeoff thrust control function. The method comprises the steps that FADEC sends the ATTCS trigger input values of an aircraft to the avionics system of the aircraft; the ATTCS trigger input values sent by the ATTCS are exchanged in the avionics system; the avionics system judges whether the ATTCS function is triggered or not; the avionics system sends a judgment result to the FADEC; and the FADEC controls whether the thrust is increased or not.

Description

technical field [0001] The invention belongs to the field of aero-engine control, and relates to a system and method for realizing the engine automatic take-off thrust control function, which is used for automatically increasing the thrust of another engine when one engine fails during the take-off or go-around stage of an aircraft, and is applicable to An aircraft equipped with an Automatic Take-off Thrust Control System (hereinafter referred to as ATTCS). Background technique [0002] ATTCS is a control system equipped on the aircraft to automatically increase the thrust of the working engine when any engine fails. Meet the thrust requirements for go-around and take-off. [0003] For twin-engine aircraft, the current implementation method is to directly communicate between the engine full authority digital engine controllers (Full Authority Digital Engine Control, hereinafter abbreviated as FADEC) of the two engines (such as figure 1 shown), each engine FADEC judges whet...

AI Technical Summary

Problems solved by technology

[0004] The problems existing in the existing technology are: the direct connection between the two engine FADECs, the isolation is not high; because the ATTCS trigger logic is integrated in the FADEC, the aircraft manufacturer lacks design autonomy; for mature FADECs that do not have the ATTCS function, There is no inter-communication interface between FADECs. If you want to apply it to a new type of aircraft that requires ATTCS functions, you need to change the FADEC hardware, resulting in longer development cycles and increased costs.
