These test technologies include advanced pressure and temperature measurement, qualitative and quantitative off-body measurement techniques, advanced static and dynamic pressure sensitive paint, advanced load balances, including flow-through balances for powered testing, and model deformation measurement systems for aeroelastic test. Flight testing leverages similar technology and extends into remote thermal imaging techniques for direct aerothermodynamic measurements of flight vehicles and technologies like background oriented Schlieren techniques for off-body flow measurement, visualization and interaction.","hasChildren":false,"hasInteriorContent":true}],"startTrl":2,"currentTrl":4,"endTrl":4,"benefits":"Our proposed technology has broad applicability across NASA's Aeronautics Research Mission Directorate (ARMD) and is especially relevant to the Airspace Operations and Safety Program and Advanced Air Vehicles Program. When fully developed, our technology can provide continuous, lightweight, rain-erosion resistant icing protection without adding manufacturing complexity or affecting payload for fixed and rotary wing vehicles. Our proposed technology is also in close alignment with NASA's Unmanned Aerial Systems (UAS) research. By mitigating the hazards of flight into icing conditions, our technology will dramatically increase options for flight path, range, altitude and duration of unmanned missions.
Icephobic coatings have numerous potential commercial applications within civil aviation, rail, wind energy, maritime transport, and logistics industries. Potential applications include airframes, rail infrastructure, railcars, switches, wind turbines, shipboard structures, and transit equipment. An economical, reliable, readily renewable, and long-lasting passive anti-icing solution could potentially improve the overall safety, performance, and efficiency of the future transportation system.","description":"Existing aircraft ice protection systems operate at the expense of other payload and add significant weight, power requirements, system complexity, or cost. A completely passive technology that would prevent ice accretion is highly desired, but no known technique has reached a level of effectiveness, durability and cost-efficiency to merit commercialization. Helicity Technologies proposes to integrate our proprietary icephobic liquid into a durable, easily renewable, environmentally friendly, icephobic composite that does not distort airflow and adds negligible weight. In Phase I, we will develop a cellulose nanopaper base layer for the storage and replenishment of our functional fluid to dramatically extend its useful life. Methods for increasing cellulose nanopaper strength and elasticity, and improved control of porosity will be explored. The resulting icephobic composite prototype will be tested for performance under simulated icing conditions in an icing wind tunnel.","startYear":2016,"startMonth":6,"endYear":2016,"endMonth":12,"statusDescription":"Completed","principalInvestigators":[{"contactId":292322,"canUserEdit":false,"firstName":"Liang","lastName":"Wang","fullName":"Liang

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.
