SprayCool worked with Naval Air Systems Command (NAVAIR) to complete a Proof of Concept demonstration of a SprayCool enclosure onto one of the Navy's tactical aircraft. PMA-234, the program management office for the Navy's electronic warfare aircraft, immediately showed interest in the technology. SprayCool and PMA-234 discussed possible projects and settled on the EA-6B Aft Power Supply (APS), which had a reputation of being the highest reliability offender on the airplane. Located in the tail section of the aircraft, the APS was subject to high temperature and vibration, and was experiencing a mean-time between removal (MTBR) of approximately 150 hours. SprayCool developed a replacement APS which was subjected to stringent testing for shock and vibration, temperature and altitude, high positive and negative G force, electro-magnetic interference, catapult launch, and arrested landing. The SprayCool variant APS accumulated over 600 hours during the testprogram. Further, the SprayCool APS afforded a 22% decrease in weight which was immediately reengineered back into the unit to expand its capability on deck... functionality that was not possible prior to the SprayCool enclosure.
