Abstract:
A Novel Coupling Technique for Solving the Euler Equations Over Complete Aircraft
To increase the design throughput of complex full aircraft configurations, a method
which is both computationally efficient and has minimal setup time is required. This
project will develop a new procedure for coupling a cartesian, multigrid Euler code
with a second Euler technique using a body-filled mesh. The method, coupled with
an iteration scheme, combines the advantages of two different gridding techniques
to produce a resulting scheme which will facilitate rapid model setup. The research
is aimed at providing a practical Euler method for complete aircraft configurations
including nozzle afterbody and inlet integration studies.
This novel technique would lead to an improved design capability for complex aircraft,
including a faster throughput of design and reduced amount of wind tunnel testing.
