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

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.
