Abstract: Revolutionary IsoCool™ technology from Frontline Aerospace can save more than $2 Billion for the US Air Force and provide sustainable range, endurance and operational performance for the C-130 fleet – the backbone of the global military tactical transport system. This new compressor enhancement will improve fuel efficiency for cruise or provide more power for hot, high altitude take offs when needed. This bolt-on retrofit, with no engine rebuild required is complementary and additive to the Rolls-Royce C-130 Series 3.5 program.
