Jet blast at and near airports poses a risk in areas where aircraft are operating in proximity to vehicles, equipment, employees, passengers, and the public (e.g., aprons, near construction sites, adjoining public areas). Incorporating jet blast assessment in the design and layout of these areas would enhance safety, but literature and data on jet blast exposure are limited, and little guidance has been developed on jet blast hazard assessment. Research is needed to develop a tool to help practitioners improve their estimates of jet blast exposure based on local parameters.
The objective of this research is to develop a jet blast estimation tool and accompanying user guide. The tool should, at a minimum:
Specific airport conditions (e.g., terrain, meteorology);
Typical air carrier, general aviation, and military aircraft/engine makes and models; and
Common thrust settings (i.e., idle, breakaway, multi- and single-engine taxi, and takeoff);
Provide an easy-to-use interface (e.g., dropdown menus, text boxes, callouts);
Permit input and output to be presented in imperial and metric units; and
Produce output in tabular and graphic (e.g., isotherms, isobars, grids) formats capable of being exported, to the extent feasible, to airport planning and design tools (e.g., ArcGIS, AutoCAD).
Note: See Special Note A.
The user guide should include, at a minimum:
Instructions for using the tool and exporting output to airport planning and design tools;
Suggested default settings;
Description of tool data sources, assumptions, and limitations; and
The ACRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective. The work proposed must be divided into tasks, and proposers must describe the work proposed in each task in detail.
The research plan should include, at a minimum:
1. Technical memo summarizing literature, potential data sources for tool development, and recommended aircraft/engine makes and models to be included in the estimation tool and a rationale for their inclusion;
2. Technical memo documenting the proposed methodology for calculating jet blast output values;
3. Interim report describing work to date, including a description, framework, logic of the tool, and a validation and Beta test plan; and
4. Technical memo presenting the results of the validation and Beta test plan with recommended improvements.
The research plan should also include, at a minimum, the following checkpoints with the ACRP project panel: (1) kickoff web meeting to be held within 1 month of contract execution to discuss the amplified work plan; (2) web meeting to confirm the aircraft/engine makes and models to be included in the estimation tool; (3) interim meeting to review the results of the interim report; and (4) web meeting to review results of validation and Beta test plan and confirm proposed tool refinements.
Note: Following receipt of the interim report, there should be 2 months for ACRP review and comments and for the interim meeting.
The final deliverables will include:
Jet blast estimation tool;
Tool documentation and code;
Technical report documenting the research process and results;
Summary of Key Findings (see Special Note F);
Further Recommended Research Memo (see Special Note G); and
Memo titled “Implementation of Research Findings and Products” (see Special Note H).
Note: Following receipt of the draft final deliverables, there should be 3 months for ACRP review and comments and for contractor preparation of the final deliverables. For budgeting purposes, proposers should assume that ACRP will provide access to web-enabled teleconference services and will pay panel members’ travel costs for the in-person interim meeting. Proposers should assume that the meeting will be held in Washington, DC.
A. The tool must use readily available, commercial, off-the-shelf software (e.g., Microsoft Excel, Microsoft Access, interactive PDF). The tool software shall not require users to install executables files on a local computer.
B. The proposed research team should include expertise in technical writing, fluid dynamics, and software development.
C. Proposals are evaluated by the ACRP staff and project panels consisting of individuals collectively very knowledgeable in the problem area. Selection of an agency is made by the project panel considering the following factors: (1) the proposer's demonstrated understanding of the problem; (2) the merit of the proposed research approach and experiment design; (3) the experience, qualifications, and objectivity of the research team in the same or closely related problem area; (4) the plan for ensuring application of results; (5) how the proposer approaches inclusion and diversity in the composition of their team and research approach, including participation by certified Disadvantaged Business Enterprises; and, if relevant, (6) the adequacy of the facilities.
Note: The proposer's approach to inclusion and diversity as well as participation by Disadvantaged Business Enterprises should be incorporated in Item 12 of the proposal.
D. Proposals should include a task-by-task breakdown of labor hours for each staff member as shown in Figure 4 in the brochure, "Information and Instructions for Preparing Proposals" (http://onlinepubs.trb.org/onlinepubs/crp/docs/ProposalPrep.pdf). Proposals also should include a breakdown of all costs (e.g., wages, indirect costs, travel, materials, and total) for each task using Figures 5 and 6 in the brochure. Please note that TRB Cooperative Research Program subawards (selected proposers are considered subawards to the National Academy of Sciences, the parent organization of TRB) must comply with 2 CFR 200 – Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards. These requirements include a provision that proposers without a “federally” Negotiated Indirect Costs Rate Agreement (NICRA) shall be subject to a maximum allowable indirect rate of 10% of Modified Total Direct Costs. Modified Total Direct Costs include all salaries and wages, applicable fringe benefits, materials and supplies, services, travel, and up to the first $25,000 of each lower-tier subaward and subcontract. Modified Total Direct Costs exclude equipment, capital expenditures, charges for patient care, rental costs, tuition remission, scholarships and fellowships, participant support costs and the portion of each lower-tier subaward and subcontract in excess of $25,000.
E. Item 4(c), "Anticipated Research Results," in each proposal must include an Implementation Plan that describes activities to promote application of the product of this research. It is expected that the implementation plan will evolve during the project; however, proposals must describe, as a minimum, the following: (a) the "product" expected from the research, (b) the audience or "market" for this product, (c) a realistic assessment of impediments to successful implementation, (d) the institutions and individuals who might take leadership in applying the research product, (e) the activities necessary for successful implementation, and (f) the criteria for judging the progress and consequences of implementation.
F. The Summary of Key Findings will be a stand-alone document. It should (a) convey the most pertinent and applicable results of the project’s research; (b) be geared toward the airport industry practitioner while minimizing technical language; (c) present results using text and graphics as appropriate; and (d) encourage readers to explore the primary project deliverables. The Summary of Key Findings should be limited to no more than 4 pages.

It should (a) identify logical follow-on research that would benefit the industry yet was beyond the original scope and budget of the project; (b) describe how the proposed follow-on research relates to ACRP’s research roadmaps, if applicable; and (c) for the highest priority research needs, include research ideas and/or problem statements to be added to ACRP’s IdeaHub, the program’s online repository of research needs.
H. The technical memorandum titled, “Implementation of Research Findings and Products” should provide: (a) recommended tactics to facilitate implementation; (b) possible institutions/partners and their potential implementation role; (c) potential impediments to successful implementation; (d) metrics to measure extend of product use and benefit; (e) related FAA guidance; and (f) appendices as needed. An annotated template for the memorandum is found here: http://onlinepubs.trb.org/onlinepubs/acrp/ACRP_Implementation_TechMemo_Template_2019.docx.
I. Item 5 in the proposal, "Qualifications of the Research Team," must include a section labeled "Disclosure." Information relevant to the ACRP's need to ensure objectivity and to be aware of possible sources of significant financial or organizational conflict of interest in conducting the research must be presented in this section of the proposal. For example, under certain conditions, ownership of the proposing agency, other organizational relationships, or proprietary rights and interests could be perceived as jeopardizing an objective approach to the research effort, and proposers are asked to disclose any such circumstances and to explain how they will be accounted for in this study. If there are no issues related to objectivity, this should be stated.
