WITNESSS "WIreless Technologies for Novel Enhancement of Systems and Structures Serviceability"

A consortium of UK aerospace companies is developing wireless sensors that can transmit data from inside aircraft engines during flight, replacing the heavy cables currently used for testing and monitoring. Today, monitoring the structural health of aircraft components—such as engine casings, rotor blades, or wing joints—requires physical wiring. These cables add weight, increase fuel consumption, and are difficult to install in hard-to-reach areas. The problem is especially acute for aero engines and helicopters, where vibration and heat make wired connections unreliable. WiTNESSS aims to prove that wireless data transmission can work reliably under those extreme conditions. If the technology succeeds, aircraft manufacturers could reduce weight, simplify maintenance, and monitor critical components continuously throughout a flight rather than only during ground inspections. The £1.6m project, led by TRW Conekt with partners from across the UK aerospace sector, focuses on de-risking the wireless approach for certification. The immediate impact is on testing and structural health monitoring—not passenger connectivity—but lighter, more efficient aircraft would ultimately reduce fuel costs and emissions for airlines and travellers.
