TheÂ Defense Advanced Research Projects Agency has developedÂ mathematical tools and methods to help designers understand risks associated with the design and modeling of large military systems such asÂ aerospace vehicles and engines.
Research teams under DARPA’s Enabling Quantification of Uncertainty in Physical Systems program have developedÂ uncertainty quantification tools toÂ increase chances that new military systemsÂ will perform as designed,Â DARPA said Wednesday.
“We aim to make UQ a tractable part of simulation and modeling even for the most complex of design problems,” said Fariba Fahroo, a DARPA program manager.
Mathematical tools developed underÂ DARPA’s EQUiPS program are intended to supportÂ various systemsÂ such asÂ aerospace structures andÂ integrated circuits, Fahroo added.
AÂ Brown University-led EQUiPS research group is creatingÂ theoretical foundations for theÂ Design Under Uncertainty toolÂ that aims toÂ simplify design processes for defense systems that face numerous development uncertainties.
The team — composed of the Massachusetts Institute of Technology, Virginia Tech, University of California and the Naval Postgraduate School — is also developingÂ an unconventional hydrofoil surface sea vessel designed to function atÂ a speed of more than 120 knots in calm sea states and 60 knots in extreme sea states.
Another researchÂ team,Â led by Stanford University, uses EQUiPS methods in a project that looks toÂ optimize the design for a supersonic jet engine exhaust nozzle and provideÂ maximum thrust efficiency.
Stanford collaboratesÂ with the Colorado School of Mines, University of Michigan and Sandia National Laboratories on the supersonic nozzle study,Â DARPA said.
