Multidisciplinary Optimization
At
Langley Research Center, research is underway to apply
high-performance computing technologies to the multidisciplinary
design optimization (MDO) of Reusable Launch Vehicles
(RLV). Various analysis codes are being integrated
using a commercially developed framework such as iSIGHT.
The framework allows the use of networked heterogeneous
workstations, vector supercomputers, and a scalable
parallel testbed.
The
framework also allows easy addition or deletion of
analysis codes and facilitates changes in the control
flow of the MDO process through a graphical user interface.
 Initially,
coarse-grained parallelism is being used to generate
many vehicle designs simultaneously for trade studies.
This capability to perform conceptual MDO using low-fidelity
codes will be demonstrated on a full RLV configuration
during the coming year.
Later,
high-fidelity analysis codes will be incorporated,
giving RLV designers, for the first time, the capability
to perform preliminary vehicle design with complex
multidisciplinary interactions in a reasonable amount
of time.
