DRY AIR PROTECTION OF AIR FORCE AIRCRAFT

It is very common in any operational air force that the aircraft are frequently stored in hangers. The main reason for this is to rule out weather influences on the aircraft body and internal equipment. These hangers, in a variety of sizes, can be found on any airfield and occasionally on board naval vessels. Although the use of hangers rules out the effect of direct rainfall on the aircrafts body, moisture in the air ensures corrosion and degradation of the electronics still occurs. For this reason dehumidification is used.

BENEFITS
• Increased aircraft readiness
• Reduced operating costs
• Reduced component replacement costs
• Low equipment operating & Maintenance costs
• Extended service

INCREASED AIRCRAFT READINESS
Trail results show a large increase in the Mean Time Between Failures (MTBF) and Mean Time Arising (MTA)

REDUCED OPERATING COSTS
Percentage man-hour reduction for selected avionics systems was:
• Missile Control System 22%
• Inertial Navigation System 23%
• Communication System 25%
• Total man-hour reduction for 1st line fault arising, all causes was 27%

REDUCED COMPONENT REPLACEMENT COST
The reduced incidents of corrosion on engine components and airframe results in longer life expectation of components, and allows a lower level of component stock to be maintained.
