Propulsion airframe integration design and
analysis has many challenges as we move into
the 21st century. Along with the conventional
challenges of integrating a propulsion system on
an aircraft, new technologies and new business
drivers dictate innovative approaches to the
design process be developed and applied.
On the technical side, new innovations in jet
noise suppression and new aircraft concepts
such as the Blended Wing Body (BWB) will give
rise to many challenges in propulsion system
performance, operability, and meeting system
requirements such as thrust reverse capability.
Aircraft engine and aircraft manufacturers must
have the appropriate design and analysis tools in
place which provide the ability to react quickly
to inevitable design changes, driven by
constantly changing requirements, during the
product development cycle.
On the business side, the rapid globalization
of the business dictates that the latest electronic
technology be utilized to enable speed in
communication with global customers as well as
revenue sharing partners. More than ever, cost
and schedules dictate the use of analytical
methods to minimize the amount of qualification
testing. Design and analysis software must be
flexible and capable of integrating CAD/CAM
and CAE tools while maintaining configuration
control of the product.
The following paper describes some of the
new technical challenges facing the industry.
Innovative methods of addressing those
challenges are described.
