Description

FC Load Bench Test Device {Flight Load Data Recorder Bench Test Device}

FIELD OF THE INVENTION The present invention relates to an FDial bench test apparatus that enables the FDL storage test to be performed at a simple setting prior to installing a flight load data recorder (FLDR) and a plurality of measuring devices on an aircraft.

In general, the aircraft is equipped with a flight load recording device for recording and storing the load value of each part of the aircraft separately from the flight load measurement that can be confirmed in the cockpit.

Typically, such a flight load recording apparatus is installed in each part of the aircraft, a plurality of measuring means for outputting the measured value, that is, ADM (Air Data Module), pitch rate sensor (Pitch Rate Sensor), roll rate sensor (Roll) Rate sensor), dual accelerometer, stress gauge, and the like, and the RTDL storing and recording the measurement data transmitted from these measuring means.

In order to accurately install the flight load recording apparatus on the aircraft, the FDL is mounted on one side of the aircraft, and each measurement means is distributed to each required measurement part on the aircraft, and then connected to the FDL via a track.

In addition, the FDL storage test is performed to determine whether the measured values transmitted from each of the installed measuring means are recorded correctly and without omission on the loaded RTD, thereby confirming that the flight load recording device is operating correctly. shall.

In the prior art, for such an RTD storage test, an operating power was applied from the aircraft to the FCDL during the ground test of the aircraft, and it was checked whether the measured value transmitted from the measuring means installed in each part was recorded in the FCDL. .

By the way, the following problems arise when the conventional RTD storage test is performed.

That is, if a test finds an abnormality in the RTD or the measuring means, the aircraft ground test is interrupted and the power is turned off to the RTDAL. It may need to be replaced or replaced.

Therefore, since the flight load recording device must be separated or installed a plurality of times according to the result of the FDL storage test, human and time loss is generated according to the work.

The present invention was devised to solve these problems, and it is possible to simply test whether the measured values output from each measuring means of the flight load recording device are normally stored in the FDL before installing the flight load recording device in the aircraft. It is an object of the present invention to solve the human and time loss caused by the conventional FDial bench test apparatus.

In order to achieve the above object, the present invention provides a bench test apparatus for the FDL storage test of the flight load recording device composed of the FDL and a plurality of measuring means. DC part seating groove and a plurality of measuring means seating grooves are formed at one inner side to seat a plurality of measuring means respectively, and are fixedly mounted on the tile side of the case part and are supplied with AC power from the outside. A power supply unit having a connecting cable to perform the function of converting the output signal to a power supply and supplying the DC voltage to the power supply at the time of the FRT storage. It consists of a test connection which performs the function of interconnecting the measuring means of the.

At this time, the power supply and the end of the connection cable is provided with an interface jack for convenience of connection, the case is provided with a cable fixing tab for fixing the test connection.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention in detail.

First, in adding reference numerals to components of each drawing, the same components are described so as to have the same reference numerals as much as possible even if displayed on different drawings.

1 is a perspective view showing the configuration of an FC dial bench test apparatus according to a preferred embodiment of the present invention.

As illustrated, the FDL storage test apparatus 100 according to the preferred embodiment of the present invention includes a case unit 110, a power supply unit 120, and a test connection unit 130.

On the inner side of the case 110, the FC dial mounting groove 111 and the plurality of measuring means seating grooves 112 to 116 so as to seat the RT dial and the plurality of measuring means, respectively, in the RT storage test. ) Is formed.

The power supply unit 120 is fixedly mounted on the tile side of the case unit 110, and receives the AC power from the outside to convert the DC voltage of 28 volts and outputs the DC voltage. It is provided with a connection cable 121 to supply the DC voltage to the power supply to the RT.

The test connection unit 130 is composed of a cable for interconnecting the RF dial and a plurality of measuring means during the FC storage test, the end of the cable is provided with an interface jack 131 for easy connection.

Meanwhile, in order to prevent the test connection unit 130 from being tangled in a complicated manner, the cable fixing tab 118 is provided in the case unit 110 to fix the test connection unit 130.

FIG. 2 is a block diagram illustrating a configuration of an FC storage test using the FM dial bench test apparatus 100 shown in FIG. 1. The FM dial 200 and the respective measurements are measured during the FC dial 200 test. The means 300 to 340 are respectively seated in the FDL seating groove 111 and the measuring means seating grooves 112 to 116 formed in the case part 110, and the test connection part 130 is also fixed to the cable fixing tab 118. To be fixed.

As shown in FIG. 2, a DC voltage of 28 volts output from the power supply unit 120 is supplied to the FDL 200 so that the FDL 200 operates, and the FDL 200 is operated at each angle. The driving means is supplied to the measuring means 300 to 340, ie, the MD 300, the pitch rate sensor 310, the roll rate sensor 320, the dual accelerometer 330, and the stress gauge 340.

Thus, the set state has the same effect as setting the load recording apparatus in the aircraft.

Because, as mentioned above, the flight load recording device is independent of the other devices of the aircraft due to its characteristics, and even if it is installed in the aircraft and tested as in the related art, it merely supplies the operating power of the FDL 200 inside the aircraft. Because there is no other action.

Therefore, when the RT Dial 200 and each measuring device 300 to 340 are set in the FC Dial Bench Test Apparatus 100 according to the present invention, the FC Dial 200 is stored under the same conditions as those installed in the aircraft. Tests will be available.

As mentioned above, although preferred embodiments of the present invention have been described in detail, those of ordinary skill in the art to which the present invention pertains should realize the present invention without departing from the spirit and scope of the present invention as defined in the appended claims. It will be appreciated that various modifications or changes can be made. Accordingly, modifications to future embodiments of the present invention will not depart from the technology of the present invention.

As described above, according to the present invention, the FDL storage test can be easily carried out by setting a flight load recording device, that is, a FTDL and a plurality of measurement devices, in the FTDL bench test device before installing in an aircraft. Pre-calibration repairs and replacements are possible.

Therefore, there is no need to perform unnecessary installation repetition work as in the prior art has the advantage that can eliminate the human time loss.
