Description
Technical Field
The invention relates to the technical field of airplane testing, in particular to a method and a system for testing and analyzing airplane severe weather environment faults based on BowTie.
Background
The airplane and the ground protection equipment thereof inevitably encounter severe weather conditions such as high temperature, high cold, damp heat, rainfall, snowfall, fog fall, freezing rain, blowing, solar radiation and the like in the service process, and the complex severe weather conditions can cause adverse effects on the physical or chemical characteristics of the airplane and the ground protection equipment composition materials thereof, cause performance degradation and function limitation, and even threaten combat enabling, and on the other hand, the severe weather can directly cause the use function failure of the airplane to cause major flight accidents. For example, when an airplane takes off under severe weather conditions such as snowfall, fog fall, rainfall and the like, a pilot crashes the airplane due to low visibility misoperation, a transporter freezes due to the fact that the transporter meets with freezing rain, and the airplane can take off to execute tasks after large-area ice melting is carried out.
One fault survey in the united states on coastal air force bases shows that the climate causes 73% of faults and other factors cause 27% of faults. The problems that an aileron shaft is frozen, an Auxiliary Power Unit (APU) and an engine cannot be started, an undercarriage moves slowly and asynchronously, oil of a hydraulic system leaks, the capacity of an environment control system is insufficient and the like exist in the American C-5 'silver river' transport plane under the high and cold condition, and the environmental adaptability of other models of the American air force is found in different degrees in the using process. These environmental compliance issues threaten normal use of the aircraft.
BowTie analysis (also known as "BowTie analysis") is based on the initial performance of risk analysis in the manner of bowties using a "triangular model" (Tripod Beta Models). The BowTie method is mainly used for risk assessment, risk management, accident investigation and analysis, risk audit and the like. The status of a particular risk can be better accounted for to help people learn about the risk system and the prevention and control measure system. In the BowTie analysis model, the top-level event is taken as a core, the possible reason for the occurrence of the top-level event is analyzed forwards (accident tree analysis), the possible subsequent events after the top-level event occurs are analyzed backwards (event tree analysis), and then a barrier is set in a targeted mode for prevention and control (Swiss cheese model).
As China does not have a laboratory and test simulation equipment for the comprehensive environment test of the whole airplane, the comprehensive environment adaptability test of the airplane before test flight can be carried out only in the field for waiting for proper meteorological conditions, so that the test period is long and the cost is high.
The invention provides an airplane fault analysis method based on a severe climate environment, which is used for establishing an airplane climate environment fault mathematical analysis model and a fault tree model, researching an airplane fault prediction method based on airplane climate factor related accident/accident symptom statistical analysis and providing support for development of laboratory airplane climate environment adaptability test design and test verification.

Further, the fault tree in step S1-2 classifies the faults of the aircraft under the severe weather conditions into five major categories, i.e., a mechanical fault, an air path fault, an oil path fault, a communication fault, and a circuit fault, and the severe weather corresponding to the mechanical fault includes: high temperature, low temperature, freeze, snowfall, sand and dust, salt fog, the bad weather that the gas circuit trouble corresponds includes: low temperature, freeze, sand and dust, the bad weather that oil circuit trouble corresponds includes: high temperature, low temperature, sand and dust, the bad weather that communication trouble corresponds includes: icing, rainfall, sand and dust, the adverse weather that circuit fault corresponds includes: the method has the advantages that the method can be used for directly selecting corresponding airplane climate tests according to different fault types, such as damp heat, icing, rainfall, snowfall, sand dust and salt fog.

Preferably, the left side of the BowTie graph is used to show climate environmental factors, the center point of the BowTie graph is the top-level event, and the right side of the BowTie graph is used to show the corresponding potential consequences.
BowTie is a risk analysis and management method, which adopts a visual and concise structured method to analyze risks, and focuses the security risk analysis on the connection between risk control and management systems. Therefore, the system not only can help a security manager systematically and comprehensively analyze the risks, but also can really realize the management of the security risks. This method combines the analysis of the cause (on the left side of the bow-tie) and the consequence (on the right side of the bow-tie) to make a detailed analysis of the events with security risks (called top-level events, located in the center of the bow-tie). The complete BowTie diagram can illustrate the risk (source), top-level events, the cause and potential consequences of the top-level events, and the risk control measures (measures taken to maintain an ideal state with respect to adverse impact or intent) that are established to minimize the risk.
Further preferably, the aircraft climate test comprises: the simulation system comprises a low-temperature environment simulation system, a high-temperature environment simulation system, a temperature daily cycle environment simulation system, a humidity environment simulation system, a solar radiation environment simulation system, a rain/wind-rain environment simulation system, a snow/wind-snow environment simulation system, a fog environment simulation system and an ice/freezing rain environment simulation system, and can cover all severe climate environments possibly encountered during the service period of the airplane as far as possible, so that a better prevention effect is achieved.
The existing common risk analysis methods include an accident tree analysis method and an event tree analysis method, but the accident tree analysis method and the event tree analysis method have limitations, which mainly include two reasons: firstly, as the accident tree and the event tree become larger, bulkier and more complex, the method is difficult to understand and use by the application personnel; second, in the work environment where the fault tree or event tree analysis is performed, there are too many variables, interferences and unknown factors. For example, even if the devices are identical, there may be different failure rates for different companies installed. How to handle facilities and processes, how operators and managers make decisions cannot be quantified. The only way is to manage such risks qualitatively. And qualitative risk analysis can be carried out on the complex operation environment by adopting the BowTie method.
The invention has the beneficial effects that:
(1) the invention aims at the design requirements of airplane environment adaptability tests, statistically analyzes airplane accidents/accident symptoms caused by severe weather environments, establishes a BowTie model diagram of airplane severe weather environment faults, analyzes the influence of airplane fault events caused by severe weather, and provides a pre-prevention main measure and a post-control method. The method has good correspondence between reasons and consequence forming mechanisms, is simple and easy to understand, provides reference for ensuring safe service of the airplane in severe weather environment, and lays a foundation for development of adaptability test design and test verification of the airplane climate environment in a laboratory;
(2) the method has good correspondence between the failure reasons and consequence forming mechanisms of the airplane severe climate environment, is beneficial to making preventive measures and control methods, is simple and easy to understand, and ensures that the mapping relation between the airplane severe climate environment failure and the environment factors is clear on the basis of data in a domestic and foreign flight accident database;
