Abstract
The impact of the electromagnetic environment upon the operational capability of aeronautic equipment, systems and platforms is known
as electromagnetic environmental effects (E3).
Their influence is becoming bigger in modern air platforms due to the increase of fly-by-wire systems in substitution of traditional
mechanical options.
Moreover, in the search of cost-effective approaches, notable parts of current aircraft are also being gradually made of composite
materials (such as carbon fiber composite, CFC, aramid fibers, fiberglass, etc) and other even more innovative materials (doped rubber,
graphene) are starting to be used for certain applications.
Unmanned aerial vehicles (UAV), who have attired the attention of manufacturers in the two last decades and have experienced a
notorious development since, are a particularly relevant example of aeronautic platforms with a high percentage of these kinds of
materials. The electromagnetic performance of these non-metallic choices has to be assessed with respect to the aforementioned
menaces. Consequently, in order to warrant the correct functioning of equipment, systems and platforms, the aeronautic industry is
required to surpass different electromagnetic compatibility (EMC) certification processes based on military and aeronautic standards which
traditionally rely on experimental testing.
Bearing this in mind, the UAVE3 project hereby presented aims to develop innovative, cost and time-effective analysis and testing
methodologies integrating advanced electromagnetic modelling and simulation approaches, for use across the whole life-cycle of new
generation composite unmanned aerial vehicle (UAV), including design, prototyping, certification, maintenance, overhaul and continuous
airworthiness.
To do so, a bottom-up methodology is suggested, meaning that a number of incrementally difficult scenarios with different test cases will
be proposed and then built, measured and simulated to help and conceive a final technology demonstrator. The rationale for the
demonstrator is to construct a rigorously controlled and characterized generic object that incorporates features of interest to the aeronautic
community, such as composite and other innovative materials, coupling through apertures and joints, coupling to transmission lines, etc.
And among the different electromagnetic disciplines encompassed in the E3 denomination the focus will be made on the most relevant
ones in terms of potential threat to aircraft safety, namely, lightning indirect effects (LIE), electromagnetic pulse (EMP) and high-intensity
radiated fields (HIRF).
The partners of this project (INTA, UGR, UPC) and the fully-supporting companies (Airbus Defense and Space (Airbus DS), ONERA and
CIMNE) have wide experience in the matters related to the expressed challenges and, in particular, they have collaborated together in past
national (MINECO UAVEMI) and international (FP7 HIRF-SE) research projects centred in the application of EM simulations to E3/EMC
problems. The achievement of the above mentioned expected results can be attained by the synergic effort of the UAVE3 partners, who
will develop and issue a work of excellence on research and cutting-edge development on EM modelling, EM characterization of materials
and discontinuities, EM testing and air vehicle EMC certification.
