Automatic ignition and temperature control method for aviation kerosene and gas generator

Abstract

The invention provides an automatic ignition and temperature control method for an aviation kerosene and gas generator, and relates to an ignition and temperature control method for a combustor. A function implementing method has characteristics of automatic ignition of a combustor in a blowing experiment for a hypersonic aircraft and characteristics of automatic high-precision temperature control. Adoption of expert control mainly comprises that an intelligent technology of an expert is used to guide engineering control, and the engineering control is required to reach an expert control level. Because a combustion process is complicated, and multi-parameter and multi-loop coordination control is related, the knowledge of the combustion expert is summarized in a knowledge base, and after field data are reasoned by the expert, corresponding expert decisions or control outputs are obtained. The control method has high reliability and stability, meets the requirement of a user on a modern management test, and can be used for a thermal environment simulation test of a hypersonic aircraft structure; the testing time and the testing cost are saved; and the economic benefit is high.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 201110098384.1. technical field [0002] The invention relates to a method for realizing the ignition and temperature automatic control functions of an aviation kerosene gas generator. The invention belongs to the field of computer automatic control and intelligent control method design. Background technique [0003] A gas generator mainly utilizes aviation kerosene combustion to generate high-temperature gas flow, and can be used in the field of high-temperature environment simulation. [0004] The ignition process of aviation kerosene is very complicated, and the timing of fuel supply and sparking is required to be in place, otherwise it is easy to fail to ignite, and if the ignition fails and the fuel supply is not stopped in time, it is likely to cause "flashback" and endanger the safety of the fuel system. On the other hand, aviation kerosene combustion is a complex and dangerous proc...

Problems solved by technology

[0005] For this reason, at present, the existing aviation kerosene gas generating equipment in my country often has ignition problems, and most of them manually adjust the fuel flow according to the temperature requirements of the outlet gas flow, which can neither realize continuous automatic control nor accurately control the oil / gas ratio, which seriously affects Temperature Control Accuracy
