Problems solved by technology

[0004] 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

Embodiment Construction

[0012] figure 1 Shown is a flow chart of the automatic control ignition method according to an embodiment of the present invention. The process includes:

[0013] Start step (101), mainly comprises the initialization of data,

[0014] Carry out the judgment (112) of whether lower limit reports to the police, if the oil supply quantity has reached the lower limit, then terminate operation and enter exit step, otherwise enter oil filter alarm (113) judgment, if oil filter alarm, then terminate operation and enter exit step. If there are no two alarms, start the oil pump and carry out the (102) step, and obtain the initial oil supply flow (103) step by querying the expert database. Query the fuel supply expert database (104), adjust the fuel flow of the auxiliary combustion chamber (105) and the fuel flow of the main combustion chamber (106) to be the ignition flow. Start ignition (107), including setting timer (as setting 45s) and opening auxiliary combustion chamber, main co...

Abstract

The invention discloses an ignition and temperature control method for a combustion chamber. The function realizing method has the characteristics of automatic ignition and automatic high-precision temperature control of the combustion chamber for a blowing experiment of a hypersonic aircraft. The expert control mainly means that engineering control is guided by using an expert intelligent technology to reach the expert control level. The combustion process is complex and relates to multi-parameter and multi-loop coordinated control, so that knowledge of combustion expert is summarized to a knowledge base; and testing site data are reasoned by experts to obtain corresponding expert decision or control output. The control method has the advantages of higher reliability and stability and favorable economic benefit; the requirement for modern management tests is met and the test time and funds are saved; and the ignition and temperature control method can be used for a thermal environment simulation test of a hypersonic aircraft structure.

Description

technical field [0001] 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 [0002] 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. [0003] 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 process, and there is a complex nonlinear law between the outlet temperature and the inlet air temperature o...
