Off course, mid term review is a moment
of reflection and revision, when it is time
to summarize the work performed and
plan forward for the future.
And it is also time to publish the first
AEROMUCO newsletter, where the
mentioned synthesizing effort is reported.

The main objective of this work package
is the development of coatings that are
able to reduce the accretion and
adhesion of ice on aerodynamic surfaces.
To achieve this goal, two main tasks have
been performed:
•
Production of nano/micro-structured
nano/
polymeric coatings (by CSEM,
CREST and PNP)
•
Surface functionalization of selected
coatings with either hydrophobic or
hydrophilic components.
•
The functionalization of the surface
with ‘antifreeze’ agent aims at
mimicking the properties of proteins
of some arctic fishes or insects
inhibiting the blood freezing.
EADS is responsible for the testing of the
developed coatings in regard to their
freezing time delay and ice adhesion
properties.
Si nano/micro-pillars

A wide selection of functional coatings
and structured surfaces has been
developed.
Preparation of structured surfaces:
•

EADS): really challenging to achieve,
since most of the polymers were
thermoset resins.

coatings (collaboration with CREST,
EADS, CASSIDIAN)
Tests of moulding of UV-curable

coatings (collaboration with EADS):

low values for the adhesion strength to
ice.
Furthermore, initial testing are undergoing
at EADS IW lab icing wind tunnel.
Significant progress has been made in
the delay of freezing of supercooled
droplets on the coatings and the
reduction of ice adhesion.
The freezing time delay tests performed
at EADS mainly show the influence of the
roughness and the hydrophobicity. The
freezing time delay of the Methacryloxy
based sol-gel coatings (CREST) is
slightly longer than that of the highly
cross-linked, the Flourinated and the PU
type coatings of CREST. The Thermally
stable sol-gel coating shows the lowest
performance in the tests. Referring to the
samples modified by CSEM, the PUR
A1+F3 coating is slightly better than the
HPUR A1+F3 sample.

Work Package 3
The primary objective of this work
package is to develop surface coatings or
surface modification processes for aircraft
leading edges (e.g. on the wing,
empennage or nacelle) that are capable
of reducing or eliminating the adhesion of
biological
contaminants,
specifically
airborne insects.
During the first 18 month following main
achievements may be listed:
•

To achieve the aims of WP 4, a broad
assessment campaign including lab tests
has been performed and flight validation
is planned.
The general work in this work package
includes:
•
Comparison and assessment of
erosion test methods including
analysis of the resulting damage
patterns for proving sustainability of
reference and developed coatings.

have
been
systematically compared.

Work Package 5
The objectives of the WP5 are related to
the management and the valorisation of
the knowledge created within the project,
with the final aim of achieving a wide
impact of the project results.
WP5, in particular, is aimed at three main
objectives:
•
Allowing easy communication and
maximum transparency for all
involved partners and increasing the
synergy of the cooperation during
the project
•
Undertaking and monitoring actions
that will pave the way for broad
dissemination of the project results
•
Setting-up
up an Exploitation plan that
will define the exploitation path and
rules related to the results
generated by the project, both
internally
within
the
project
consortium
and
