VIBRATION TEST REPORT

Thli t«sr rtport contains fh« results of th« vibration t«sts porformtd on the AN/rRN-41 TACAN Navigational Sot.

1. Test Idonttflcatlon. Vibration test as defined In Appendix V-C of the Equipment Test Plan for Navigational Set, TACAN, AN/rRN-41.

2. Functional Purpose of Test. AN/rRN-41 system qualification.

3. Test Objectives. To demonstrate that the system meets the requirements of Specification No. 404L-701-5017A, Part 1, Paragraph 3.2.5.2.3 (20 August 1976).

4. Description of Test Article. The AN/rRN-41 system In the manportable configuration Is made up of three packages consisting of the following:

Receiver-Transmitter, Radio, RT-1202/r

Antenna, AS-3132/r

Ancillary Group

Each of these three units and the Direct Current Power Filter, F-1439Af were subjected to the vibration test as described In the equipment test plan.

5. Summary of Test Results.

a. Pre and Post Vibration Operational Tests. All pre and post vibration operational tests were run successfully.

b. Vibration Tests. There were no resonances observed during the search made on any of the units tested. Therefore, sinusoidal cycling was performed per the procedure.

c. Visual Inspection. The visual Inspection showed that there was no damage Incurred to the units as a result of the vibration test.

6. Description of Test Setup. Each of the units under test was separately strapped to the vibration fixture and vibrated on three mutually perpendicular axes. The vibration fixture was a Ling Vibration Exciter Model 290 and a Ling Sine Wave Controller Model SCO-100. Pictures showing the vibration test set up are found In attachment 1 of this report.

7. Photographs. See Attachment 1.

8. Test Equipment. See Attachment 2.

9. Test Data. See Attachment 3.

10. Test Conditions. The tests were conducted In a test laboratory environment.

11. Ttrt- Results Analysts. Th« AN/rRN-41 system passed successfully the vibration tests as disecrfbed In the equipment test plan. The vibration tests revealed no design weaknesses within the system.

Because the antenna and filter box were vibrated when a complete system was not available for system operational testing r individual operational tests for these units were run before and after vibration. The proceedures for these Individual unit tests are included In Attachment 4.

12. Certification. The data sheets shown in Attachment 2 have been signed by a Montek Quality Assurance representative and a DCAS representative, certifying that the test results are authentic, accurate/ current and In accordance with the related test plan.

FILTER, DIRECT CURRENT POWER, F-1439A

Operational Tests - For Pre and Post Mechanical Tests

1. Resistance Test. Using the digital voltmeter measure the resistance from J1-1 to J1-2. Record on data sheet. It should be 35.7 ± 4Ci.

2. Current limit the 28 volt power supply to .5 amps and connect the +28 VDC to Jl-2 and the return to J1-1 and observe that because of current limiting the power supply voltage is reduced to less than 1 volt. Check data sheet.

3. Turn the power supply off and connect the +28 VDC lead to J1-1 and the return to Jl-2. Observe with an oscilloscope J2-1 when the power supply is turned ON. The voltage should rise to 28 VDC and obtain this voltage in not leu than 10 M seconds.

4. Connect a 2.80 resistor as a load across J2 pins 1 and 2. Apply 28 VDC to the input of the filter box J1-1 and the return to Jl-2. Measure the voltage from JM to J2-1. Record on data sheet. It should be less than 1.5 volts.

ANTENNA OPERATIONAL TESTS FOR PRE AND POST MECHANICAL TESTS

I. Ant«nna SpMd cmd Reference Trigg«n.

To perform this subtest, proceed as follows:

a. Connect the equipment as shown in Figure 1 with the test box ANT POWER switch in the OFF position.

b. Adjust the power supplies for input voltages of 4-24 ± 0.5 Vdc and +5.0 ± 0.1 Vdc and place the ANT POWER Switch in the ON position.

c. With the counter, measure the period of the 15 Hz, 135 Hz and 1350 Hz TRIGGERS at the test box and observe these triggers with the oscilloscope. Record the following characteristics on the data sheets.

(1) Period between triggers

15 Hz trigger 66.666 ± .133 ms 135 Hz trigger 7407 i 14.8 ps 1350 Hz trigger 740 ± 10 ps

(2) Trigger base line level ^ "^.5 Vdc

(3) Pulse Amplitude Z. 3.0 Vdc negative from base line

(4) Pulse rise time - (10 - 90%) I. 20 ps

II. Antenna Speed Error. To perform this test, proceed as follows:

a. Connect the equipment as shown in Figure 1.

b. Energize the equipment and monitor the antenna speed error on the test interface box. After the antenna gets up to speed, the signal should be low (0.7 Vdc Max.)

c. Cause an antenna speed error by momentarily switching off the antenna on signal at the antenna interface test box and observe that the antenna speed error signal goes high (3.5 Vdc min.). Check data sheet.

III. Voltage Standing Wave Ratio (VSWR). To perform this subtest, proceed as follows:

a. Remove pedestal from base of antenna assembly and connect the equipment as as shown in Figure 2.

b. Place the signal generator in the square wave modulated mode and adjust the frequency to 1151 MHz. With gain and vernier controls set at approximately 1/2 minimum on the SWR meter, adjust the probe penetration of the slotted line to obtain an on-scale reading on the SWR meter. Move the probe along the slotted line until a maximum indication is obtained. By interacting adjustments of gain, vernier, and frequency controls on the SWR meter and by interacting adjustments of probe penetration and probe location on the slotted line, obtain a SWR m eter reading of 1.0.

c. Move the probe along the slotted line until a minimum voltage is displayed on the SWR meter. Record meter SWR reading on data sheet. The VSWR should be less than 1.5 to 1.
