Smart Monitoring System for Aircraft Structures 2011-01-2714
TRIADE is a European Union project that focuses on the
development of technological building blocks for Structure Health
Monitoring (SHM) sensing devices in aeronautics. It is funded under
the 7th framework program. In terms of objectives, the TRIADE
project focuses on providing these technological building blocks
and fully integrated prototypes in order to achieve power
generation, power conservation, energy management and embedded
powerful intelligence for data processing and storage for SHM
sensing devices.
The principal technological building blocks that the TRIADE
project will provide are: - A low profile battery with high energy
density which will be able to function in a harsh environment, - An
energy harvester from vibration and electromagnetic RF, - Ultra low
power sensors which will be designed in SOI technology, and - A
neural network for data recording and damage assessment.
The smart tag will be the size of a credit card (dimension
85x55x4 mm) and will support remote sensors. It will be embedded
under the last composite layer or attached on the structure of the
aircraft. It will be autonomous as all the power needed will be
provided by the onboard rechargeable battery. It is wireless and
the data stored will be transferred to the base station by using
the RFID communication protocols through an RFID reader. It will
record temperature, relative humidity, pressure, strain, vibration
and acoustic emissions whenever the flight domain is overrun.
The structure health monitoring capability that the TRIADE
project offers is planned to be applied in 2 application domains:
on helicopters with Eurocopter and PZL Swidnik as end-users, and on
airplanes with EADS Deutschland GmbH and Dassault Aviation as
end-users. The different requirements from each end-user have been
unified on the smart tag with minimal compromises to accommodate
of.
