replacing typical hydraulic systems, such
as wing flaps, that power different elements
of flight. New systems will be electric
ones, with power and signal wires
delivering the controls to the wings.
Hydraulic systems are heavy, but they
have been reliably employed in aircraft
since the beginning of flight. “The aircraft
industry is very conservative,” says
Quintana
of SENER, which is designing
these new electromechanical systems.
“It’s a very safe system, very conservative.
But if you are trying to evolve into
lighter aircraft, the electromechanical
system is significantly lighter than a
hydraulic one.”
In addition, Indra is one of the top producers
of flight simulators in the world,
supplying simulation equipment all over
Europe and to the United States as well,
where they are used to train American
navy pilots. The company recently supplied
new training simulators for U.S.
Navy Seahawk helicopters. This technology
will be part of a new EADS-CASA
flight training center, which will be an
addition to the company’s manufacturing
and research centers near Seville.

Spanish companies have been involved
with the European space program for
decades, and Spain is a member of the
European Space Agency, contributing
subsystems to the launcher of the International
Space Station. Today, Spanish
companies and research institutions
have a significant and growing presence
in all major ESA scientific missions.
The Spanish government has recently
rededicated itself to the space sector’s
growth with the Strategic Plan 2007–
2011, which includes a $267 million
investment focusing on research and
development.
Some of the same companies that have
been creating new technologies for the
aeronautics sector have turned their attention
to space as well. For example, Indra,
the information systems company, has
developed control centers for satellites.
Indra is also responsible for developing
stations that process search-and-rescue
systems for Galileo, the European navigation
satellite system. GMV, a company
with more than 20 years’ experience in
engineering and software for space and
aviation, was recently selected to
provide the mission planning and scheduling
system for NASA’s Lunar Reconnaissance
Orbiter, the NASA Goddard
mission to the moon scheduled for
late 2008.
SENER has been working in space
for 35 years, developing deployment,
positioning, and pointing systems. The
company is partnering with the United
States for the Mars Sample Laboratory,
designing the pointing mechanism for
the Rover antenna.
An important project for SENER in
the space sector is a partnership with a
number of other European companies on
an in-orbit servicing system. After satellites
have been in orbit for the intended
lifetime, about 10 to 15 years, they need
to be retired from service. “The idea
behind this [system],” says Quintana of
SENER, “is to extend the life of the satellite
by sending a vehicle that will dock
with the existing satellite and provide
extra years of operation by supplying
control and fuel.” SENER is in charge of
the guidance, navigation, and control of
the vehicle; a launch is planned within
the next few years.
One small company in northern
Spain, Advanced Dynamic Systems
(ADS), has focused its research on what
are known as satellite orbit control
actuators. These systems can turn the
satellite around to orient the satellite
for a given task, such as aiming a camera
in a specific direction. ADS is working
on control moment gyros, which
provide agility and fast movement for
observation satellites. There are only a
handful of companies in the world
developing these systems. “Our project
is based on existing technology,” says
Jorge Serra, director of business development
for ADS, “but with an innovative
approach that provides better
performance than what is in use today,
and with about half of the weight and
volume of current systems.”
The idea came about when an engineer,
one of the company’s founders,
