According to the present invention, the flight data is recorded using the previously recorded flight data, and the validity of the corrected flight data is verified and recorded in the database, thereby eliminating the need for a separate validation process during the aircraft analysis. Relates to a device.

In general, in order to perform aircraft-related analysis, such as fatigue analysis of an aircraft, analysis of the cause of an accident, or life prediction, it is necessary to record flight data of the aircraft.

Therefore, when performing flight test or actual flight of an aircraft, a separate recording and recording device capable of storing flight data indicating the flight status of the aircraft should be installed to manage the flight operation history of the aircraft.

Such a recording device is called a flight data recording device. In general, the flight data recording device receives a flight data such as an altitude and a speed obtained from each sensor during a flight, and stores the data in a database.

At this time, the flight data recorded through the flight data recording device is used as the main input data for performing various aircraft analysis, such as aircraft fatigue analysis and accident investigation, so that the flight data recorded in the flight data recording device is the accuracy and Of course, the reliability should be high.                         

In order to secure such reliability, prior to inputting flight data recorded in a flight data recording device into an aircraft analysis system, the operator reviews the flight data one by one to determine whether the data meets predetermined criteria. Discrimination was made.

However, when the operator reviews the flight data recorded in the flight data recording device and performs the validation thereof, even a very skilled worker takes 5 minutes or more to review a single flight data. The validation and correction of flight data requires a tremendous amount of time.

In addition to the excessive time required, the verification of flight data, which is dependent on manpower as in the past, may result in different verification results according to the operator's experience, so that it is not possible to carry out consistent validation and data correction. It is unclear and unclear, and ultimately has a problem of lowering the reliability of the flight data itself.

The present invention was devised to solve these problems, and after setting the channel-based correction criteria and effective range of the flight data by using the flight data recorded initially, the flight data obtained from the aircraft meets the preset channel-specific correction criteria. By providing an aircraft flight data recording device that compensates for and validates and records the corrected flight data, it eliminates the unnecessary waste of time that has occurred in the past by eliminating the need for a separate validation process during aircraft analysis. The aim is to improve the reliability of flight data due to the elimination and automated validation.

In order to achieve the above object, the present invention provides an aircraft flight data recording apparatus mounted on an aircraft, comprising: a database storing an initial flight data record of an aircraft, and a flight altitude from flight data acquisition sensors installed in each part of the aircraft; Using the flight data input module to receive flight data such as speed, vertical load multiplier, horizontal load multiplier, and strain, and initial flight data records stored in the database, correction criteria are set for each channel, and the flight data input module is used. Flight data correction module that corrects the input flight data according to a preset correction standard, and sets the normal reference range for each channel for validating the flight data, and the flight data corrected by the flight data correction module exists within the normal reference range. Check if it is normal or fire The database includes a flight data validation module that determines data, and controls the interaction and data flow between the above-described modules as a whole, and determines whether the flight data performed through the flight data validation module and the normal and bad judgment results of the flight data are determined. A control module performing a function of storing the data into a control module, a flight data output / retrieval module that outputs an inquiry result according to a user condition and a result of determining whether the flight data is stored in a database, and a flight data validation Trigger app inspection module that checks whether the trigger channel of the flight data verified through the module is missing and the flight flight data recorder's own various setting values and the normal judgment criteria of the self-diagnosis result are set, and the self-diagnosis is performed. Read if it exceeds Self-diagnosis over diagnosis consists of the module.

As shown, the aircraft flight data recording apparatus 100 according to a preferred embodiment of the present invention is a database 170, flight data input module 110, flight data correction module 120, flight data validation module ( 130, the trigger map inspection module 140, the self-diagnosis module 150, flight data output / query module 160 and the control module 101, a plurality of flight data mounted on the aircraft installed in each part of the aircraft It is interlocked with the acquisition sensors 200.

The database 170 stores a flight data record of an aircraft recorded initially, and stores a flight data and a result of verification of the currently input, corrected and verified flight.

The flight data input module 110 receives a flight data such as flight altitude, speed, vertical load multiplier, horizontal load multiplier, strain, and the like from the flight data acquisition sensors 200 installed in each part of the aircraft.

The flight data correction module 120 sets correction criteria for each channel using the initially recorded flight data stored in the database 170, and sets the flight data input by the flight data input module 110. Calibrate according to the calibration standard.

The reason for calibrating flight data is that the standard altitude does not coincide with the standard altitude at the time of initial flight data recorder setup, so the error is caused by the air pressure. This is because the standard altitude should be changed to determine the validity of the altitude data because errors can occur up to 1500 feet.

In the case of speed data, flight data cannot be reliable at speeds of 50 knots or less due to the pressure difference maintained after the hydrostatic pressure system.

At this time, the determination of the correction method is preferably referenced with reference to about 15,000 hours of flight data stored in the database 170.

Flight data validation module 130 sets the normal reference range for each channel of the flight data, such as altitude and speed, vertical load multiplier, horizontal load multiplier and strain, and the flight corrected through the flight data correction module 120 It verifies the validity of the flight data by checking whether the data fall within the reference range and determining normal or bad data.

The trigger map inspection module 140 performs a function of checking whether the verified flight data is missing a trigger channel. Flight variables used as trigger channels are vertical load multipliers, horizontal load multipliers, and strains.If any one of these variables is not used as a trigger variable, it cannot be used as input data for subsequent flight data analysis. Must be inspected.

The self-diagnosis module 150 sets normal determination criteria of various setting values and self-diagnosis results of the aircraft flight data recording apparatus 100 itself, and conducts self-diagnosis to read whether the predetermined determination criteria are exceeded to detect device abnormalities. Perform diagnostics.

The flight data output / retrieval module 160 monitors or prints the result of the normal and bad determination of the flight data performed by the flight data validation module 130 and the result of the self-diagnosis performed by the self-diagnosis module 150. This function outputs the search result according to the condition desired by the user.

The control module 101 performs overall functions of controlling the interaction and data flow between the above-described modules 110 to 170, and the flight data validation module 130, the self-diagnosis module 150, and the trigger map inspection module. The flight data and the result data output from the 140 is stored in the database 170.
