Problems solved by technology

[0009] In this Advanced Model B, all four engines share a backup mode switch and there are no warning lights to indicate that the engines should go into backup control mode, so the pilot has no way to intuitively know when one of the engine control systems loses atmospheric data Understand that the backup control mode should be entered at this time, which may bring potential threats to the flight process of the aircraft

Embodiment Construction

[0028] Below, refer to figure 1 The backup mode switch capable of realizing the method for triggering the engine backup control mode of the present invention will be briefly described. figure 1 It is a schematic diagram of a backup mode switch capable of realizing the method of triggering the engine backup control mode of the present invention.

[0029] figure 1 The backup mode switch 10 shown is a double-layer switch, and at the same time, the backup mode switch 10 can control two engines at the same time.

[0030] The upper layer of the backup mode switch 10 is an indicator light 20, which is marked as "automatic (AUTO)". When the indicator light 20 is on, it means that one or both engines in the two engines automatically enters the soft backup control mode.

[0031] The lower layer of the backup mode switch 10 is a push switch 30, which is marked as "manual (MAN)". When the pilot presses the push switch 30, it means that the two engine controllers enter the hard backup...

Abstract

Provided is a method of triggering an engine back-up control mode. In the situation that a push switch of a back-up mode switch is not pressed down and controllers of engines do not receive effective atmosphere data, the controllers of one or more engines losing the atmosphere data automatically enter a soft back-up control mode, and if the push switch is still not pressed down after the soft back-up control mode lasts for set time, the controllers of the one or more engines losing the atmosphere data automatically enter a hard back-up control mode. In the situation that the push switch is pressed down, the controllers of the engines enter the hard back-up control mode simultaneously; when the engine back-up control mode is executed, once the effective atmosphere data can be received, the controllers quit the engine back-up control mode, and an engine normal control mode is executed.

Description

technical field [0001] The invention relates to a method for triggering an engine backup control mode of an aircraft, and more particularly to a trigger method and an engine backup control system for triggering an engine to enter a backup control mode when the aircraft loses atmospheric data. Background technique [0002] Atmospheric data (mainly total temperature, total pressure and other parameters) are important parameters in the flight process of the aircraft. The aircraft needs to collect flight atmospheric data regularly to control the aircraft engine. Once the atmospheric data during flight is lost, the aircraft engine It is impossible to output thrust to the engine according to the normal control mode. [0003] At this time, in order to allow the engine to work normally and ensure the basic flight safety of the aircraft, the engine should enter the backup control mode to work when the aircraft loses the atmospheric data during flight. [0004] As the engine backup c...
