Problems solved by technology
[0002] At present, our company does not have a special tester for the calibration of finished products, which cannot meet the requirements of the radio compass system for pre-installation calibration. It cannot test the various functions and detailed technical indicators of the radio compass system. If it is installed directly, it cannot guarantee the finished product. the quality of
When the system is powered on to check that the system fails, there is no effective means to judge whether it is the fault of the finished product itself or the fault of the on-board circuit or other cross-linking equipment. The fault can only be eliminated on the plane, and the fault phenomenon cannot be reproduced on the ground.

Embodiment Construction
[0013] The invention provides a radio compass orientation sensitivity test device, such as figure 1 shown, including:
[0014] The UHF signal generator 3 is connected with the ADF signal simulator 2 by a radio frequency cable, and sends a radio frequency signal to the ADF signal simulator 2;
[0015] The radio compass orientation sensitivity test module 9 is connected with the compass receiver 1, receives the audio output produced by the compass receiver 1 according to the radio frequency signal, and sends the audio output to the earphone 5;
[0016] Audio power meter 6 is connected with radio compass orientation sensitivity test module 9, and displays the power value of audio output to earphone 5;
[0017] The wireless electromagnetic indicator 10 is connected with the radio compass orientation sensitivity test module 9, and displays the azimuth angle when the ADF signal simulator 2 demodulates the received radio frequency signal and forwards it to the compass receiver 1;

The invention provides a testing apparatus for directional sensitivity of a radio compass, which belongs to the field of aircraft avionics. The testing apparatus comprises: an UHF signal generator 3, which is connected with an ADF signal simulator 2 through a radiofrequency cable and sends a radiofrequency signal to the ADF signal simulator 2; a radio compass directional sensitivity testing module 9, which is connected with a compass receiver 1 and used for receiving audio output generated by the compass receiver 1 according to the radiofrequency signal and sending the audio output to an earphone 5; an audio power meter 6, which is connected with the radio compass directional sensitivity testing module 9 and used for displaying the power value of the audio output sent to the earphone 5; and a radio magnetic indicator 10, which is connected with the radio compass directional sensitivity testing module 9 and used for displaying an azimuth angle when the radiofrequency signal demodulated by the ADF signal simulator 2 is transmitted to the compass receiver 1.
Description
technical field [0001] The invention belongs to the field of aircraft avionics and relates to a radio compass orientation sensitivity test device. Background technique [0002] At present, our company does not have a special tester for the calibration of finished products, which cannot meet the requirements of the radio compass system for pre-installation calibration. It cannot test the various functions and detailed technical indicators of the radio compass system. If it is installed directly, it cannot guarantee the finished product. the quality of. When the system is powered on and checked for failures, there is no effective means to determine whether it is the fault of the finished product itself or the failure of the on-board wiring or other cross-linking equipment. The failure can only be eliminated on the plane, and the failure phenomenon cannot be reproduced on the ground.
