What this opportunity is
The NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking a custom 3-channel constant-temperature-anemometer (CTA) system for supersonic and hypersonic flow measurements. This project is suitable for small businesses with expertise in research-grade systems, specifically those with experience in developing high-bandwidth flow measurement systems. As a Special Notice, this opportunity is not a formal solicitation and may be a call for information or a request for a proposal, so interested parties should track the notice closely for further details. The project has a 5-month work schedule and requires a system with better overall performance than commercially available options in the US.
Analysis by Mindy, grounded in the SAM.gov notice.
Description
Statement of Work
1. Introduction/Background: Current CTA systems that are commercially available in the US
from companies like Dantec Dynamics and TSI Incorporated do not meet our required
specifications for high-bandwidth, research-grade systems applicable for high-speed flow
applications. The commercial systems are now overly simplified for plug-and-play type
applications and are more tailored for university laboratories. This new CTA system
promises the flexibility needed for expert users. We have commercial CTAs currently on the
market in our organization that are more applicable to lower speed flows and the older
commercial units with higher performance are no longer on the market. We have
attempted to work with these manufacturers in past years to deliver a system for our
current needs, but we have been unsuccessful. The older commercial systems from the
previously named companies that met our needs are no longer available and the units we
have are failing due to age (units are 30+ years old).
2. Scope of Work: This project will result in a custom-built 3-channel constant temperature
anemometer (CTA) system that promises to address our needs for supersonic / hypersonic
flow measurements.
3. Objectives: Provide high-bandwidth flow measurements in supersonic / hypersonic flow
regimes while maintain low system noise. Goal is to provide a CTA system with better
overall performance than commercially available systems in the US.
4. Description of the Work/Contractor Tasks: Project is to develop a 3-channel CTA system
based on the earlier functional 3-channel CTA system developed by this contractor Minor
adjustments will be implemented to improve the user experience versus the first 3-channel
CTA system. See the accompanying specification document for more details.
5. Deliverables: The primary deliverable for the proposed project is a second three-channel
CTA system consisting of three CTA Modules and a single Power Supply-Oscillator Module.
Additional deliverables will include a user manual along the lines of the one delivered with
the first 3-channel CTA system. Work schedule is expected to be approximately 5 months
from contract award.
