SALT FOG TEST REPORT

for the

NAVIGATIONAL SET, TACAN, AN/TRN-41

This report describes the salt fog test as defined in the Equipment Test Plan for Navigational

Set, TACAN, AN/TRN-41, 131500-415.

1. Test Identification. Salt fog test as defined in Appendix IV-F (salt fog test procedure)

of the Equipment Test Plan for Navigational Set, TACAN, AN/1TRN-41.

2. Functional Purpose of Test. This test forms a part of the AN/TRN-41 system qualification

tests.

3. Test Objectives. To demonstrate that the AN/TRN-41 will meet the salt fog requirements

of paragraphs 3.2.5.1.5 and 4.2.1.4.3.6 of Specification No. 404L-701-5017A, Part I of 2

parts (20 August 1976).

4. Description of Test Article. The AN/TRN-41 system consisting of the following was used

for the tests:

Receiver-Transmitter RT-1202/T

Antenna AS-31 32/T

Antenna Support AB-1237/T

Filter, DC Power F-1439/TInterconnecting Cables

5. Summary of Test Results. The AN/TRN-41 showed no functional degradation during the

salt fog test. Some parts showed rust during the test. This was further degradation from the

humidity tests.

6. Description of Test Facilities and Procedures. The test facilities and test procedures are

described in Appendix IV-F of the Equipment Test Plan.

7. Test Setup Diagrams. The test setup diagrams are provided in Appendix IV-F of the

Equipment Test Plan.

8. Test Equipment. See Attachment I for test equipment used for the salt fog test and the

pretest, test and post test operational tests.

9. Test Data. Attachment 2 contains the data sheets for the salt fog test, pretest, test

and post test operational tests.

10. Test Conditions. The system was in a salt fog chamber at 35oC with a salt fog being

applied for 48 hours.

11. Test Results Analysis. Comparison of pretest, test and post test operational data showed

no functional degradation during the salt fog test. Some parts as described on the salt fog

test data sheet in Attachment 2, exhibited rust. These parts were expedited for use on the

preproduction systems and did not meet the requirements of the specification control drawings.

The parts used on production will have proper corrosion resistant characteristics.

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.-.

RF AARKS At the conclusion of the talt fog test, the system operated properly. There was n5

degradation in performance based upon Icomparison of test data. Listed are the noted mechanical

discrepancies observed during visual inspection. Mechanical Engineering is presently evaluating

the parts for corrective action and resolution prior to production.

Note: The items noted as discrepant on the tripod had deteriorated during humidityand accelera-

tion or further degradation occurred during salt fog testing.

DISCREPANCIES Tripod--The spring pin, P/N MS16562-216, shows evidence of rust.

The thumb screw, P/N 910569-001, shows evidence of rust.

The 1/4 turn fastener D-Ring, P/N 930048, used for mounting the receiver-transmitter to the

tripod is rusted.

I lP DC Filter-The MS35650-304 nut used for mounting clamp 919594-001 shows evidence of rust.Tka mryntjnQ rlnmp 910594-001 shows minor evidence of rust at the spot welds.
