In practically all studies to date involving configuration multidisciplinary shape optimization, dynamic AE/ASE constraints were left out, thus, rendering the design results incomplete. Flutter, gust stresses, vibration, fatigue, ride comfort, handling qualities -- all extremely important -- still cannot be accounted for in an automated design process involving configuration shape variations. Proposed here is the creation of a comprehensive design-oriented CFD-based unsteady-aerodynamic methodology to enhance current flight vehicle shape MDO capabilities by the creation of AE/ASE shape sensitivities and efficient approximations tailored for large-scale design optimization. ZONA Technology's proven ZEUS code serves as the aerodynamic base for this development. In Phase II aerodynamic shape sensitivities for AE/ASE shape optimization will be developed for general 3D configurations made of lifting surfaces and bodies. The subsonic, transonic, supersonic, and hypersonic flight regimes will be covered. Integration with shape optimization finite-element structural codes will be demonstrated, covering diverse AE/ASE constraints including flutter and gust response. This new general capability will fit any aerospace vehicle MDO environment, and will provide a critically needed MDO building block.","startYear":2009,"startMonth":12,"endYear":2011,"endMonth":12,"statusDescription":"Completed","programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":863,"projectId":8680,"transitionDate":"2011-12-01","path":"Closed Out","infoText":"Closed out","infoTextExtra":"","dateText":"December 2011"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
