A system and method for realizing engine automatic take-off thrust control function

Abstract

The invention relates to a system for realizing the engine automatic take-off thrust control function, comprising: a first engine FADEC, a second engine FADEC, an avionics system electrically connected to the first engine FADEC and the second engine FADEC, wherein the first engine FADEC and The second engine FADECs each send the ATTCS trigger input value to the avionics system, and the avionics system performs ATTCS trigger logic judgment based on the ATTCS trigger input value to trigger ATTCS, and sends an instruction to adjust the engine thrust to the first engine FADEC or the second engine FADEC . The present invention also relates to a method for realizing the engine automatic take-off thrust control function, comprising the following steps: FADEC sends the ATTCS trigger input value of the aircraft to the avionics system of the aircraft; the ATTCS trigger input value sent by the FADEC is exchanged within the avionics system; The electrical system judges whether to trigger the ATTCS function; the avionics system sends the judgment result to the FADEC; the FADEC controls whether to increase the thrust.

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.
