Unlike Pitot-static and other pressure-based devices, which experience serious limitations in accuracy, pneumatic lags, and frequency response in thin upper atmospheres and at low speeds, FASS will measure airspeed all the way to zero knots and flow angularity to a fraction of a degree with practically zero-lag. It will perform equally well at sea level as well at high altitudes and even in the thin Martian atmosphere with relative immunity to EMI and RFI. Calibrated hot-film gages could also be used to simultaneously obtain total temperature. FASS addresses important flight-operation and flight research problems that have crucial impact on vehicle performance, stability & control, structural loads, and pilot action. FASS will permit direct integration with aircraft avionics systems including conventional instruments used for pressure, temperature, and density measurements. Hot-film gages are coated to withstand harsh environment and for protection from rain and ice. FASS is developed both as a stand-alone probe and as an embedded, non-intrusive system. Applications include aerospace and ground vehicles, submarines, ships, and measurements in the atmosphere, ocean, and in internal flows.

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.
