Abstract
The invention belongs to Computer Simulations, flight simulation technology field, and in particular to a kind of aircraft fuel system fault simulation method.Aircraft fuel system fault simulation method mainly passes through system modelling technology and equipment/component of fuel system is built up independent equipment/partial model, the performance pipe net leakage rate of system is established according to aircraft fuel system pipe network working mechanism, finally, establishing fuel system comprehensively control model in conjunction with fuel system comprehensively control logic.For the system failure and special feelings, system comprehensively control model is injected into after generating constraint and failure performance formal classification by defect content, failure.This method plays an important role to aircraft fuel system modeling and simulation.Meanwhile such method applies also for similar aircraft system emulation, such as hydraulic or power supply system, while being suitable for the research and development of ground flying training equipment.It is also extrapolated to the fields such as automotive fuel oil system and carries out simulation analysis, for design verification.
Description
Technical field
The invention belongs to system modelling, Computer Simulation and flight simulation technology fields, and in particular to a kind of fuel system
Fault simulation method.
Background technique
In system modelling, Computer Simulation and flight simulation technology field, the fault condition of fuel system depending on be must can not
It is few, especially in the ground flyings such as flight training device training cartridge is standby.By taking flight training simulator as an example, the indispensability of fuel system
In system function, it is desirable to which system has the function of this special feelings of fuel dump.In addition, system there are also amount of fuel low, fuel oil low temperature,
The fault mode of the influence of many places such as system oil leak, fuel pump failure, delivery valve failure flight management and flight safety.Therefore, exist
The operating condition of fuel system, the system emulation being determined including fault mode are directed in airplane design, ground flying training
And simulation.
Summary of the invention
The purpose of the present invention is: it realizes the mathematical simulation of failure of fuel system, passes through Computer Simulation and mathematical modeling skill
Art models aircraft fuel system, while can also record to the operation and maintenance situation during engineering simulator use.It should
Method can be applied to other similar large complicated experimental enviroments or production environment.
The technical scheme is that a kind of aircraft fuel system fault simulation method exists primarily directed to fuel system
The flight that ground carries out is special please to train expansion.According to the fault type of training goal research system, then pass through mathematical method
The fault model of fuel system is established, appliance computer emulation technology develops the fuel system for meeting flight training.This method
Mainly comprise the steps that
Step 1: combing the system structure of aircraft fuel system, decomposes to the artificial tasks of system, in general,
It is broadly divided into the system architecture of fuel system, function and performance requirement, systems operational mechanism and redundant configurations, the work of main component
Make parameter and operating condition monitoring.
Step 2: according to system unit working principle, in conjunction with emulation demand, analyse item by item emulation demand, establishes component
Mathematic simulated mode.
Step 3: according to System Working Principle and aircraft redundant configurations, fuel system pipe network simulation architecture, creation system are built
System simulation model；
Step 4: according to fault list, config failure is constrained in system simulation model.
Step 5: system development is completed according to system function and error listing.
Step 6: it is tested according to the two-stage that the design requirement of system completes system related content.
The utility model has the advantages that the present invention realizes Fuel System by system modelling and computer simulation technique caused by of the invention
The fault condition of system emulates.As airplane design divide supplementary means, failure of fuel system simulated implementation aircraft fuel system is complete
The simulation and monitoring that operating conditions management, system are run provide verifying means and verification platform for system design；Fly from ground
For row training, the fault simulation of fuel system is on the basis of the fuel system established works normally, in addition to can be carried out just
Normal system operation procedural training, moreover it is possible to the training that is free from risk be carried out to separate procedures such as the special feelings of system, failures, significantly
Reduce training cost.The technology applies also for other system emulations, such as aviation power supply and plane hydraulic system；It can also answer
Use other industries, such as automotive fuel oil system simulation analysis etc..
Detailed description of the invention

As shown in Figure 1, a kind of aircraft fuel system fault simulation method, completes system according to system simulation technology scheme
Mathematic simulated mode includes 2 steps altogether:
1) structure for combing aircraft fuel system, decomposes the artificial tasks of system: by taking twin as an example, fuel oil
System, can be with intercommunication fuel oil by the middle defeated valve of port valve-friendship equipped with 2 isolation fuel tanks.Each fuel tank is equipped with a set of independence
Oil supply system to corresponding engine oil.In addition, system also has the function of fuel dump, cross feed and injection oil transportation function
Energy.Each oil supply system is 2 remainings.By system control panel FCP open system equipment, into operating mode.In Mechatronic Systems
Monitored picture can see the pipeline fuel feeding of fuel system, oil mass information, equipment working state.
2) according to system unit, analyse item by item emulation demand, establishes the mathematic simulated mode system parameter of component.Fuel feeding system
The equipment of system mainly includes 2 oil feed pumps, a fuel feed stop valve.No. 2 fuel tanks are provided with independent APU fuel feeding system
System, direct current oil feed pump and APU fuel feeding stop valve.In addition, fuel system is equipped with fuel measurement computer FQP；In addition also match
The various kinds of sensors of system-specific is set, especially low fuel-quantity transducer；Fuel system control panel.Therefore, it is necessary to establish combustion
Fuel tank, fuel-cut valve, check valve, hands over defeated valve, oil transportation mouth, jet pump, fuel sensor and fuel oil control panel at oil feed pump
The mathematic simulated mode of FQP.
According to Fig. 2, classify to defect content, config failure constrains in system model；Complete system development.System
Special feelings class includes that fuel dump and amount of fuel are low；Failure classes include fuel feeding failure of pump, fuel feeding stop valve failure, fuel tank oil leak
