AMSTE-TA-G   (70)
SUBJECT:   Operation Desert Shield (ODS), Lessons Learned


1.   Item:   DOD Generator sets (XEP 005A1 NEP 009B)
     Problem:  The ventilation louvers which allow air to flow into the engine
compartment do not always open automatically causing the generator to over-
heat.
     Solution:  Before operating the generator, manually open the v~entilation
louvers by pulling the lever just inside the access doors.
     POC:  Dennis Craham, CSTA, DSN 298-2624.

2.   Item:   Smoke Generator ?(l059
     Problem:  High temperatures reduce the viscosity of fog oil causing the
fog oil pump pressure to be reduced.  Fog oil pressure switch is a rheostat,
when pressure is reduced, voltage is dropped across rheostat.  Heat is gener-
ated in the rheostat and is dumped onto control panel. Temperatures of oil
panel are hot enough to cause second degree burns.
     Solution:  Operators must wear gloves
     POC:  John Mallamo1 HQ TECOM, DSN 298-3766.

3.   Item:   Smoke Generator M1059
     Problem:  Lower temperatures cause fuel lines to freeze and fog oil to
congeal.
     Solution:  Use dry gas in fuel lines.  Mix fog oil with kerosene.
     POC:  John Mallamo, HQ TECOM, DSN 298-3766.

4.   Item: M17 SANATOR, Lightweight Decontamination System
     Problem:  High temperatures cause vapor lock in burner and engine.
     Solution:  Keep fuel in shaded area or use evaporative cooling techniques
such as blankets soaked in water wrapped around fuel supplies.
     POC:  John Mallamo, HQ TECOM, DSN 298-3766.

5.   Fiber Optic Cable Connectors.  When we conducted a sand and dust test on a
high speed (19.2 Mb/s) fiber optic transmission set for PM, MSCS, we found
that the connectors could be cleaned by vigorously shaking out the sand, rins-
ing them in clean water, and then shaking the water out before re-mating the
connectors.   This field cleaning method may be a suitable substitute when nor-
mal cleaning methods are not available.   In most cases, measured attenuation
following this procedure was approximately equal to that when using normal
cleaning methods.

6.   Shelter Air Conditioners.  When we conducted FAT of the Co=unication Cen-
tral, AN/TSC-99. we found that the air conditioner compressors would not oper-
ate when ambient temperatures were above 1200F.   Investigation revealed that
the ECU high pressure cutoff valve was engaging.   The ECUs were made to oper-
ate by bleeding freon from the system, thus relieving the high pressure and
allowing the compressors to engage.

7.   AVIONICs L~p Indicators.   When we performed ACES/AD FA/PPT, we found that
the Cockpit Kill Indicator lamps would not operate properly following the dust
test.   Fail~re analysis revealed that dust was on the lamp contacts, because
  press to test" switches were not properly tightened during assembly.  The
switches were tightened and the dust test repeated without problem.
