Air Force Special Operations Command and industry, sponsored two programs to demonstrate how nucleated foam washing on the CV-22 Osprey and KC-135 engines reduces specific fuel consumption and exhaust gas temperature, lowers maintenance costs, decreases carbon dioxide emissions, and extends time-on-wing. Preliminary results from the KC-135 testing, which occurred in November 2020 at Rickenbacker Air National Guard Base, Ohio, indicate a significant reduction in engine temperature using nucleated foam as opposed to water; a good indication of the potential for improved engine performance. Testing and analysis of the CV-22 foam wash began in December at Hurlburt Field, Florida, and is expected to continue through December 2021.
