Embodiment Construction

[0020] An "aero-engine start-up control system in off-plane state" designed by applying the method can realize the start-up control process of the aero-engine in the off-plane state.

[0021] 1. Overall plan

[0022] The start-up control system of an aero-engine off-board is mainly composed of a signal acquisition device, an interface circuit device, an A / D conversion device, a main control computer, a display operation device, a power supply, and a chassis, etc., such as figure 2 shown.

[0023] 2. Hardware system

[0024] (1) Master computer

[0025] The main control computer is the control core of the entire starting control system. In order to make the system have strong stability and reliability, we choose Advantech IPC-610 industrial control computer, which has a passive backplane structure and can provide 8 ISAs and 4 PCI slots, integrated 100M network adapter, with high reliability and anti-interference ability.

[0026] (2) Signal acquisition module

[0027] In ...

Abstract

The invention discloses a method for realizing starting control under the state of deplaning of an aero turbo fan engine. In the method, a main control computer is employed to collect, process, convert, display and monitor the starting parameters of a turbo starter and the turbo engine such as temperature, rotating speed, fuel delivery and the like, thus realizing control of the turbo starter andthe turbo engine and starting process under the deplaning state of the engine (deplaning state refers to the state in which the engine works independently out of control of the plane). The method integrally uses virtual instrument technology, computer control technology, signal testing and processing technology and the like to replace all the functions of an installing aero turbo fan engine automatic starting device and partial functions of an engine comprehensive regulator; the method realizes the starting control of the aero turbo fan engine under the state of deplaning for the first time and greatly enhances the cost performance and reliability of the system.

Description

technical field [0001] The invention relates to a ground start control method of an aero engine, in particular to a start control method of an aero turbofan engine in an off-machine state. Background technique [0002] The aircraft engine is the heart of the aircraft, and the performance of the engine is directly related to the safety of the aircraft. Ensuring that the engine is in good working condition is a very important task in the maintenance process of aeronautical engineering. [0003] The main features of aviation turbofan engines are high thrust, low fuel consumption and high reliability. The aviation turbofan engine is normally installed on the aircraft, and the engine start is realized jointly by the turbine starter and its control system and the engine starting system on the aircraft. [0004] In the off-plane state (off-plane state refers to the state in which the engine is separated from the control of the aircraft and works independently), the engine is sepa...
