Rolls-Royce secures research contract with US Navy to develop innovative debris detection technology
Rolls-Royce has been awarded $1 million of research funding from the US Government for digital foreign object debris (FOD) detection technology, the company said in its release.
The year-long research contract from the US Navy, will help to further develop and validate Rolls-Royce’s FanSenseTM debris monitoring system, which is currently supporting the Pegasus engine.
FanSense works by analysing the shaft speed signal of an engine and is able to detect any disruptions that arise as a result of a small object, such as stones or screws, striking an engine fan blade. The innovative technology applied as part of this service offering, will allow customers across Civil and Defence industries to detect much smaller debris entering the engine, enabling them to build a clearer picture of FOD damage and engine wear over time and will help to identify airfields that need to improve their FOD prevention practices.
FOD is estimated to cost the global aviation industry billions of dollars per year in damage and disruption. The vast majority of ingested debris currently goes undetected - only when very large items are ingested do operators have any indication that something has made its way into the engine. Rolls-Royce will continue to work with a long-standing industrial partner, Roke, to deliver the contract.
The FanSense technology adds to Rolls-Royce’s portfolio of FOD prevention offerings, including the FOD App, the FOD cloud data analysis service and FOD officers. The vision for FOD technology is to build a digital system that is able to predict FOD events before they occur by analysing data collected from the app and using vehicle tracking sensors and debris tracking radars. FanSense adds a key missing piece to this system, determining the exact time and location of historic FOD events, which will enable customers to predict the conditions in which ingestion of a harmful object is likely to occur.
