and companies have created the
Center for Aerospace and Advanced
Technology (CATEC in Spanish),
which is scheduled to open this year.
The center will focus on three major
areas of research: structures and materials;
propulsion, with research both on
engines and on fuel; and equipment,
avionics, and other onboard systems.
The center will also work with EADSCASA
on research into unmanned
aerial vehicles.
Engines
Until the late 1980s, no major Spanish
company focused on the design and
production of aeronautic engines and
turbines. It was to address this deficit that
SENER, in partnership with Rolls Royce,
founded ITP. Within only about 15 years,
the company became a top world
producer of low-pressure turbines in
aeronautic engines—the turbines that
move the fans within the engines. The
company has grown into one of the largest
aerospace companies in Spain, focusing
on innovations in engine design, manufacture,
and repair.
“It’s difficult in this market to stand
out based on just one factor,” says Iñaki
Ulizar, ITP’s director of engineering and
technology. “What makes a company
attractive is a combination of great
technology and well-trained employees.
Once we receive specifications from a
customer, we can complete the entire
module from scratch.”
The low-pressure turbine accounts
for a great deal of weight in the engine.
At ITP, current research focuses on how
to reduce noise, weight, and fuel consumption.
The general approach is to
examine the mechanics of the product
and the air flow and attempt to increase
efficiency by using new materials or
changing the aerodynamic shape of
parts. “We can make optimizations in the
design that we couldn’t make even five
years ago,” says Ulizar, “because
computer capabilities today allow us to
perform simulations overnight that give
detailed information about the aerodynamics
of the component. In the past, we
could only do this kind of simulation
to understand the physical design in
physical research projects.”
ITP also does research to improve
maintenance, repair, and overhaul activities
at its facilities near Madrid, where
the company repairs aviation engines.
New techniques involve advances in
welding, cleaning, and coating applications
using thermal sprays. Researchers
there are working in partnership with
European counterparts to investigate
reducing the use of metals such as cadmium,
chromium, and nickel in repair
work. They are also developing new

coatings and improving laser welding
techniques. At the milling center,
researchers focus on how to reduce the
thickness of the casings for large components
while protecting their strength.
They are also examining ways to enhance
the performance of milling tools by using
nanotechnology in their coatings.
ITP is one of the top companies in the
sector in terms of R&D investment.
“Years ago there was a value in Spain by
being low-cost compared to other European
countries, but today that is not the
case,” says Ulizar. “So now in Spain there
is an increased understanding that the
only way to stay competitive is by investing
in research.”
Helicopters
Eurocopter, part of the EADS family, is
setting up a manufacturing center in
Spain that will provide helicopter models
such as Tigers and EC135s for the
Spanish army. “Between the army and
the civil protection unit, we see a big
potential market in Spain,” says Jesus
Ruiz, spokesperson for Eurocopter-
España. Ruiz says that research at the
moment remains in the field of industrial
transfer, building up a manufacturing
base. But research facilities will soon
investigate the possibility of using a
greater percentage of carbon fiber composites
in helicopters.
Carbon fiber parts for these aircraft
