The ultrasonic motors developed on this program will be targeted for use in passive optics positioning systems and interferometers in IR remote sensing and space telescope applications. The above metrics were achieved during the Phase I program using a traveling wave ultrasonic motor with single crystal drive elements. Motor operation was also demonstrated at 77K. In Phase II, motor torque and speed will be increased and size, weight, and power will be further decreased by optimizing the motor design and crystal element configuration. Drive electronics optimized for operation from 300 to 77K will also be developed. Finally, the motor and electronics will be extensively tested at cryogenic conditions and under thermal cycling for reliability and repeatability. At the conclusion of the Phase II program TRS and our partners will have optimized and characterized piezoelectric ultrasonic motors capable of operating over a very broad temperature range (400 to < 77K) with significant performance improvements (torque, speed, precision, and power) over competing technologies with narrower temperature ranges.","startYear":2007,"startMonth":11,"endYear":2009,"endMonth":11,"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":164,"projectId":6212,"transitionDate":"2009-11-01","path":"Closed Out","infoText":"Closed out","infoTextExtra":"","dateText":"November 2009"}],"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.
