Commercial aviation will benefit significantly from this technology. For example, wide spread area fatigue damage has been determined to be a major source of problem for commercial aviation. Federal Aviation Administration (FAA) Regulations require that aircraft structures critical to their safe operation must not fail during flight due to damage caused by the repeated (cyclic) loads typical to its operations. This requirement generates the need for evaluating the fatigue life of critical aircraft structures. IFOS's proposed approach addresses such needs of FAA. In addition to aviation other commercial application areas of the proposed methodology include automotive, wind and gas turbines, the oil industry and land and marine vehicles qualification.
All aviation companies and other entities within this market benefit from in-flight health monitoring of their aircraft structures. An acoustic emission monitoring system attached to the aircraft structure, in the areas susceptible to fatigue and impact damage provides the data that can be used reliably to determine the health status of the aircraft structure in real time. IFOS commercialization strategy is to provide a robust and economically feasible AE monitoring system to both government and private sector fleet aircraft owners and operators. The U.S. government customers for the proposed calibration system include organizations such as NAVY, AIR FORCE and NASA.","description":"Intelligent Fiber Optic Systems Corporation (IFOS) proposes to prove the feasibility of innovations based on ultra-light-weight, ultra-high-speed, multi-channel, optical fiber sensor system for acoustics emissions (AE) monitoring for detection of impact damage and cracks in structural components in Aerospace structures. The project goals are to design an ultra-high-speed/high resolution with a small foot print fiber Bragg grating (FBG) sensor interrogator, construct a system model, test platform including embedded FBG sensors and develop signal processing algorithms to identify and measure AE signals in the presence of a quasi-static background strain field. The system model will demonstrate proof-of-principle and the test results will provide proof-of-functionality of the proposed sensor system for monitoring AE including using the advanced fiber optic sensor signal processing algorithms. AE will be simulated in an Aluminum by performing pencil break or impact hammer tests. The model test results will be compared to the measurements made concurrently by a standard single channel piezoelectric AE transducer. IFOS and its collaborators in this project will develop a Phase II strategy plan that includes development and integration strategy, potential demonstration opportunities, program schedule, and estimated costs. The key proposed innovation is a modular, light-weight, ultra-high-speed, multi-channel, optical fiber sensor system for AE monitoring.","startYear":2010,"startMonth":1,"endYear":2010,"endMonth":7,"statusDescription":"Completed","principalInvestigators":[{"contactId":479655,"canUserEdit":false,"firstName":"Vahid","lastName":"Sotoudeh","fullName":"Vahid Sotoudeh","fullNameInverted":"Sotoudeh, Vahid","primaryEmail":"Vs@Ifos.Com","publicEmail":true,"nacontact":false}],"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}],"projectManagers":[{"contactId":76557,"canUserEdit":false,"firstName":"Christine","lastName":"Jutte","fullName":"Christine V Jutte","fullNameInverted":"Jutte, Christine V","middleInitial":"V","primaryEmail":"christine.v.jutte@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":65888,"projectId":8530,"transitionDate":"2010-07-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":305999,"fileName":"SBIR_2009_1_FSC_A4.02-8652","fileSize":18860,"objectId":65888,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"18.4 KB"},"transitionId":65888,"fileId":305999}],"infoText":"Closed out","infoTextExtra":"","dateText":"July 2010"}],"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.
