Project Title:

Integrated Design and Optimization of

Thermal/Structural/Optical Systems

Technical Abstract (Limit 200 words)

Without an ability to share design tools, the

disciplines of thermal control, structures, and optics

levy worst-case performance requirements on each

other such that each specialty can contribute to a

design independently. This results in a stack-up of

margins and inevitably to over-design to the point

of rendering advance missions such as the NGST,

with its cryogenic large aperature optics, difficult to

achieve without an integrated design approach. For

example, temperature gradients in a mirror support

structure are inconsequential as long as the

required optical performance is achieved, yet

derived limits on such gradients often become a

design driver for thermal control specialists.

Recent innovations by the proposed development

team have eliminated many of the stumbling blocks

that stymied previous attempts to achieve a tight

integration between thermal control, structures, and

optics. These advances include a finite

element-compatible thermal radiation analyzer,

thermal tools compatible with CAD databases,

optimizing thermal/fluid solvers, and integrated

structures/optics design and optimization. It is now

possible to achieve not only an integrated tool suite,

but also one that can automatically find the

mimimum mass design that meets required optical

performance under all structural load cases and

thermal environments. Revolutionary designs are

expected from a revolution in the design process.

Potential Commercial Applications (Limit 200 words)

The demand for high-performance designs with

tight alignment requirements is not limited to

optical systems. Mortorola's next-generation

Iridium project, for example, is expected to employ

a small phased-array antenna with over 6kW of

dissipation and little tolerance for deflections. This

and other commerical demands for high-level

design optimization tools will assure the

commercialization of the resulting software,

including the results of the Phase I project.
