Method and device for controlling additional takeoff thrust of plane

Abstract

The invention relates to a method and device for controlling additional takeoff thrust of a plane. The method includes: receiving a first instruction for activating the additional takeoff thrust from a pilot of the plane, responding the first instruction, and sending activating signals for activating the additional takeoff thrust to each engine of available engines of the plane. After the additional takeoff thrust is activated, the pilot only needs to push a throttle lever to a normal takeoff position, and the additional takeoff thrust can be achieved. The pilot only needs to send one instruction to activate the additional takeoff thrust of each engine, and single-activation misoperation in a traditional scheme is avoided. Additionally, the first instruction can be received by a software button, and the activating signals are transmitted through a bus of the plane. Activation and closing of the additional takeoff thrust can be achieved without special buttons and transmission lines, and therefore a weight problem and an arrangement problem in the traditional scheme are solved.

Description

technical field [0001] The invention relates to the field of aircraft thrust control, in particular to a method and device for controlling the extra take-off thrust (Bump Rating) of an aircraft. Background technique [0002] Under certain conditions such as plateau, high temperature, and / or heavy aircraft weight, the normal take-off thrust level of the aircraft cannot meet the take-off performance requirements of the aircraft. In this case, the extra take-off thrust level should be used to provide greater take-off thrust. This extra takeoff thrust is often referred to as BumpRating. [0003] In the traditional scheme, the control of the extra take-off thrust is carried out through a plurality of physical buttons (also called hard buttons) arranged on the throttle console, and each physical button corresponds to an engine. figure 1 The conventional extra takeoff thrust control buttons are shown, where figure 1 (a) and figure 1 (b) shows the throttle consoles of A320 and A3...

AI Technical Summary

Problems solved by technology

[0008] 1) Special buttons and transmission lines are required, which brings weight and layout problems;

[0009] 2) When activating the extra take-off thrust, the pilot needs to manually press the physical buttons corresponding to all available engines. Once the pilot only presses the physical buttons corresponding to some of the available engines, it will cause a single-engine activation misoperation
