P&W is to collaborate with IT giant IBM to broaden performance monitoring on 4,000 operational commercial engines. The two companies intend to provide airlines with improved information on engine performance while an aircraft is in flight. The technology borrows from developments in military aviation. “Today’s aircraft engines can generate up to a half terabyte of data per flight. This data deluge can be made into a critical resource if coupled with predictive analytics, creating a valuable asset for early warning or fault detection and improved visibility in to the overall health of aircraft engines,” said Alistair Rennie, general manager for business analytics at IBM. IBM has invested $24 billion to build its data capabilities for aerospace through R&D and acquisitions.
