Engine Compartment Thermal Eval for the Short Range Recovery Product Line

Request for Information (RFI) Purpose: The United States Coast Guard (USCG), Aviation Logistics Center (ALC), Short Range Recovery (SRR)/H-65 aircraft division is issuing this request for information (RFI) for market research purposes to identify operating heat and mass flow properties of the MH-65 engine compartments during normal Coast Guard operations and information on technologies to reduce the engine compartment temperatures to allowable levels. Any final solution offered will be accompanied by a validated computational fluid dynamic (CFD) analysis, a computer 3D model of each engine installed in its respective compartment, and all test data used in the project. Background: Each MH-65 engine compartment (2 engines - left and right) houses an Arriel 2C2CG turboshaft engine that employ a 500 cubic feet per minute (CFM) exhaust fan powered by the power turbine to help cool the compartment. Each engine is capable of producing more than 1000 shaft horsepower (SHP) during single engine operations (rare) and limited to approximately 700 SHP in twin engine operation (most common mode of operation). The engines are housed by a metallic firewall and composite cowlings. The metallic firewall (forward, aft and center) is titanium and the cowlings that open (left and right), and fixed cowling (top over both engines) are carbon fiber and honeycomb laminate structures. See below photo for reference. Heat damage has been noted on some engine control and monitoring harnesses, near the engine hot section and structural components within the confined space, near the engine exhaust pipe. The maximum continuous temperature for control and monitoring harnesses is 160 degrees() Celcius (C) and a transient (30 minutes) of 180 C. For unprotected structure, the maximum continuous temperature is 150 C and the transient (5 minute) limit is 200 C. For protected structure, the temperatures are 200 C and 250 C respectively. Coast Guard testing and damaged components show that the left side experiences slightly higher temperatures than the right. Preliminary Coast Guard testing also shows inflight temperatures exceeding engine control and monitoring temperatures. Also, the right-hand side of the airframe has a hoist assembly that effects airflow near the engine. The applicable North American Industry Classification System (NAICS) code assigned to this procurement is 336412 - Aircraft Engine and Engine Parts Manufacturing and the small business size standard is 1,500 employees. Disclaimer: There is no solicitation at this time. This RFI is not a request for proposals; submission of any information in response to this request is purely voluntary; the Government will not pay for any costs incurred nor is obligated to respond. All submissions become Government property and will not be returned. After reviewing responses to this RFI, and if the USCG still plans to proceed with the acquisition, a solicitation announcement may be published on the SAM.gov website or distributed to contract holders if a strategically-sourced vehicle is deemed appropriate. It is the responsibility of the interested parties to monitor the Contract Opportunities website. Failure to respond or submit sufficiently detailed information may result in a company not being considered a likely offeror when making a decision on whether or how to set aside a solicitation for restricted competition. Regardless of the information submitted, the Government reserves the right to consider any arrangement as determined appropriate for this requirement. No proprietary, classified, confidential, or sensitive information should be included in your response to this RFI. The Government reserves the right to use any information provided by respondents for any purpose determined necessary and legally appropriate, including using technical information provided by respondents in any resultant solicitation. Request: If your organization has heat and mass flow modeling, airframe modification and airworthiness certification experience, please provide the following information: Organization name Address Website Point of contact name Point of contact email address Point of contact telephone number Socioeconomic status Unique Entity Identifier What information and/or resources would you typically need from the government to perform this effort? Does your company currently have existing government-wide acquisition contracts (GWAC) (e.g. GSA) or other strategically sourced contracts for these types of requirements that the USCG can order off? If yes, please provide contract number, what agency it is with, and agency point of contact information. What type of contract (e.g. firm-fixed-price, cost-reimbursement, etc.) have you been issued before for this type of work? Do you recommend one type or a perhaps a hybrid (i.e. a contract that allows several types)? Provide any general comments, thoughts, and feedback your company would like to share regarding this RFI. Please provide a minimum of the following in your reply - Examples of the following: creating a computational fluid dynamic (CFD) of a system; a system or subsystem heat and mass flow problem your organization solved; and technologies employed in your organization's solutions. Submission Instructions: Interested parties are invited to submit a response to the above questions by April 5, 2024, at 4:30pm EDT. Telephone responses will not be accepted. All responses and questions regarding this RFI must be emailed to Livia Pippen at contact@example.gov. Please indicate 70Z03824IB0000012 in the subject line.
