Project Title:

An Innovative Aerodynamic Engine for

the Next Generation Design System

Technical Abstract (Limit 200 words)

The key to maintaining the United States' lead in

the commercial and military aircraft markets lies in

the reduction of design cycle times. A shorter

design cycle means lower development costs, more

rapid market response, the potential for multi-point

design optimization, and the opportunity to

incorporate future high risk technologies into new

designs. Continuum Dynamics, Inc. proposes the

development of a new "aerodynamic engine" for

this next generation design system. The central

innovations in this approach are: a fast panel

methodology providing order of magnitude

reductions in both computation time and storage

requirements over existing panel methods; a

modular fast kernel which may be integrated

directly into existing panel codes, providing aircraft

manufacturers tremendously improved performance

while maintaining their existing knowledge and

design bases; and the integration of a free vortex

particle formulation into this fast panel

methodology, providing designers with an efficient

tool for modeling vortical wake and separation

phenomena. The development and integration of

these key concepts will both lead to a major

reduction in design cycle times and provide

designers with an expanded envelope modeling tool

to understand and potentially exploit unsteady,

vortical flow structures in future aircraft designs.

Potential Commercial Applications (Limit 200 words)

The ability to rapidly calculate both inviscid and

viscous/vortex-dominated flows about complex

bodies over an entire flight operating range,

constitutes a powerful new tool for assessing

performance, loads, and flow characteristics of new

and existing configurations. The technological

innovations to be developed and implemented here

will power a family of new aerodynamic design

products including: (1) a fast-panel kernel which will

be marketed directly to aircraft manufacturers and

to panel code developers for incorporation into

existing panel based design systems to yield an

order of magnitude reduction in both computation

and storage requirements; (2) a new "aerodynamic

engine" with the potential of revolutionizing the

aircraft design process, by enhancing the flow

modeling fidelity in the preliminary stages of

design; and (3) with the integration of emerging

solid modeling and optimization technologies, a

completely new preliminary design system with the

power to perform multi-point design optimization

and rapidly evaluate high risk technologies.
