Wireless sensors reach the sky

Novel wireless sensors for aircraft security systems are set to increase the competitiveness of Europe's aerospace industry.
Wireless sensors reach the sky
Efficient aircraft monitoring systems are crucial for air safety, and new wireless technologies in these systems can help raise the level of safety significantly. The EU-funded project 'Integrated wireless sensing' (WISE) studied how to integrate cutting-edge wireless technologies, where power sensors must be autonomous, into aircraft.

Today, aircraft monitoring systems rely on sensors that are hardwired within their electronic acquisition unit, a design which doesn't allow sensing to cover all parts of the aircraft. To overcome this limitation, the project worked on enabling the monitoring of new physical parameters that were not previously possible. This would increase safety, as well as reduce power consumption and emissions.

WISE also studied how to replace or simplify complicated wireless solutions that already existed with physical links when the need arose. It found ways to isolate important sensing information that contributes to aircraft safety in novel ways.

The project team successfully developed radio frequency transmission that remotely powers the sensing element. It achieved this in an open-air environment as well as in an environment comprising a metal or composite structure.

The improvements included reducing installation and operating costs, in addition to simplifying maintenance. In particular, the WISE team was able to save on installation testing by removing unnecessary wiring. It improved air intake temperature sensing accuracy, error rate, and related man-machine interface, giving way to more precise safety measures than ever before. The European aerospace industry is on the road to becoming more competitive, thanks to these safety improvements.
