Basic Research Opportunity Towards Active Control of Noise from Hot Supersonic Jets | Apply Online

Frequently Asked Questions (FAQs)

What is this funding opportunity about?

This Office of Naval Research (ONR) basic research opportunity focuses on understanding, reducing, and controlling noise generated by hot, supersonic jet exhaust plumes that contain shock structures. The main technical aim is to improve scientific understanding of how large-scale turbulent flow features form and evolve in these extreme jets, and how those features produce both near-field and far-field noise.

Who is issuing the opportunity?

The opportunity is issued by the Office of Naval Research (ONR).

What is the Funding Opportunity Number (FON)?

The notice is labeled as a Special Notice with Funding Opportunity Number 11 SN 0007.

Is this a standard grant solicitation?

The notice is labeled as a Special Notice. However, it functions as a targeted research call and directs applicants to submit proposals under a specific ONR Broad Agency Announcement (ONRBAA11-001) rather than under the Special Notice itself.

Can an application be submitted under the Special Notice (11 SN 0007) itself?

No. The Special Notice explicitly states that applicants must not submit applications under the Special Notice. Proposals must be prepared and submitted using the instructions and package associated with ONRBAA11-001.

Which solicitation package and instructions must be used to apply?

Applicants must use the application instructions and package associated with ONRBAA11-001.

What kind of proposal is required?

The submission is for full proposals.

What are the required proposal components?

The full proposal requires two main components: (1) a technical volume and (2) a cost volume.

What is the main technical goal of the research?

The core goal is to connect the physics of supersonic, shock-containing plume dynamics to the sound that propagates away from the jet, with an emphasis on approaches that could ultimately enable active noise control.

How does the opportunity define near-field noise?

Near-field noise is defined here as noise within 20 nozzle diameters of the jet axis.

How does the opportunity define far-field noise?

Far-field noise is defined here as noise beyond 100 jet diameters.

What research areas does ONR say are of particular interest?

ONR highlights several directions, including: (1) analytical and computational work such as theory development, modeling, and high-fidelity simulation to capture instability mechanisms, shock-turbulence interactions, and coherent structures; (2) establishing clear correlations between specific flow interactions and acoustic radiation to improve prediction and suggest control strategies; (3) advanced experimental diagnostics and testing including modern optical measurement techniques, time-resolved flow field measurements, and synchronized acoustics; and (4) advanced noise control design methodologies and devices, with an emphasis on active control concepts.

Does ONR emphasize modeling and simulation?

Yes. The notice calls out analytical and computational work, including theory development, modeling, and high-fidelity simulation, aimed at capturing relevant instability mechanisms, shock-turbulence interactions, and the emergence of coherent structures in hot supersonic jets.

Does ONR emphasize experiments and diagnostics?

Yes. ONR expresses interest in advanced experimental diagnostics and testing, which can include modern optical measurement techniques, time-resolved flow field measurements, and synchronized acoustics capable of resolving the plume structure and noise sources in space and time.

Is active noise control within scope?

Yes. The opportunity specifically points toward approaches that could ultimately enable active noise control and explicitly invites advanced noise control design methodologies and devices aimed at manipulating the flow or its instabilities to reduce noise.

Are passive noise treatments the main focus?

The notice emphasizes active control concepts and methodologies rather than only passive treatments, while still framing the overall effort as basic research.

How many awards does ONR expect to make?

ONR anticipated making about five awards.

What funding instruments may be used?

The listed funding instruments include cooperative agreements, grants, and procurement contracts, indicating flexibility depending on the proposer, the nature of the work, and government needs.

What is the activity category for this opportunity?

The activity category is Science and Technology and other Research and Development.

What is the CFDA number associated with this opportunity?

The CFDA number is 12.300 (Basic and Applied Scientific Research).

Is cost sharing or matching required?

No. The opportunity states that cost sharing or matching funds are not required.

Who is eligible to apply?

Eligibility is not fully spelled out in the Special Notice text. Instead, eligibility details are deferred to ONRBAA11-001, so prospective applicants were expected to consult the broader BAA for formal eligibility rules.

What was the submission deadline?

The deadline for submission was February 25, 2011.

Were late proposals allowed?

The announcement notes that late proposals could be considered only if agency time and funding availability permit.

What are the posted and creation dates listed for the notice?

The posted and creation dates are listed as January 25, 2011.

What is the archive date for the opportunity?

The archive date is March 27, 2011.

Who is the point of contact for this opportunity?

The contact listed is Lynnette Desorcie, Senior Contracting Officer.

How can the point of contact be reached?

Lynnette Desorcie can be reached by phone at 703-696-4324.

Where should Grants.gov-related questions be directed?

The notice includes a note directing Grants.gov-related questions appropriately, indicating that Grants.gov questions should be handled through the proper Grants.gov support channels rather than the contracting officer.
