As the regional and business jet markets steadily rebound, so too
do the propulsion technologies that will provide airframers and
their customers competitive advantage.
Getting it right with composites
With composites now a mainstay in most new aircraft designs, the
engineering emphasis has switched from understanding if they work
to thinking through the most efficient way to manufacture them,
such as using design-for-manufacturing software.

MRO providers are discovering ways to innovate their procedures
while remaining viable and profitable through the current downturn
in government spending.
Commercial programs are flying high
With economic regeneration underway this year, the rate of ordering
new aircraft has been at an all-time high, with the result that
backlogs for undelivered new production stretch well into the next
decade for some popular models.
Europe's aerospace industry looking
Apart from Airbus's highly visible presence in defense and
commercial aircraft, Europe also has successful capabilities in
helicopters, business jets, and aero engines, and in all these
areas their global market share is growing.
Comparing blade-element momentum modeling to 3-D
Many small unmanned aerial vehicles (SUAVs) are driven by small
scale, fixed blade propellers, and the flow produced by the
propeller can have a significant impact on the aerodynamics of the
Rapid prototyping has the potential to play a beneficial role in
unconventional autonomous airship design. By reducing model cost,
build time, difficulty of construction, and maintaining acceptable
surface quality and finish, designers have greater ability to
analyze several configurations of airships and to change the
geometry to increase stability, reduce drag, or fulfill mission
Simulating lightweight vehicles operating on discrete
Researchers characterize the mobility of autonomous reconnaissance
vehicles on terrain considered to be deformable, and represented as
a collection of bodies of spherical shape.

and minimize pilot workload.
Into the DEAP
The Distributed Electrical Aerospace Propulsion project looks
toward a future optimized integrated propulsion system that will
allow cleaner, quieter, and more efficient performance to be
incorporated into a radically innovative airframe that will feature
enclosed electrically powered fans.
Managing the deluge of data
The model-based development (MBD) process has been a key enabler of
technical advancement in the transportation industry; however, the
MBD process leads to the generation of large volumes of data
artifacts and work products. To maintain efficiency while
continuously improving the quality of products, it is necessary to
be able to manage this data in an efficient manner.
