This is not a request for proposals. This is a Request for Information (RFI) released pursuant to Federal Acquisition Regulation (FAR) 15.201(e). This RFI is for information and planning purposes only and is not to be construed as a commitment by the Government. This is not a solicitation announcement for proposals and no contract will be awarded from this announcement. The information provided in this RFI is subject to change and is not binding on the Government. All submissions become the property of the Federal Government and will not be returned. The United States Coast Guard is requesting information from industry regarding an Environmental Control System (ECS) that could replace the vapor cycle refrigeration system currently installed in the H-65 Helicopter. Replacement systems must be lighter in weight and have greater cooling capacity than the system installed presently. This solicitation has been issued to survey the market to identify suitable candidate systems and suppliers for consideration. Note: this RFI pertains to cooling systems using any technology available to include but not limited to vapor cycle, bleed air, and electrically or mechanically driven. Please respond to the following questions in additions to submission of your company’s capability statement: Company Information Please respond to the following questions: (1) Is your business a large or small business? (2) If small, does your firm qualify as a small, emergent business, or a small, disadvantaged business? (3) If disadvantaged, specify under which disadvantaged group and is your firm certified under Section 8(a) of the Small Business Act? (4) Is your firm a certified "hub zone" firm? (5) Is your firm a woman-owned or operated business? (6) Is your firm a certified Service-Disabled Veteran-Owned? (7) Is your product listed on a GSA schedule? (8) Do you have other government agencies using the product, and if so which agencies, POC's and contract numbers? (9) If possible, any POC's for civilian users for general usage of product questions. General Description The USCG H?65 Short Range Recovery (SRR) helicopter, a product of Aerospatiale Helicopter Corporation (now Airbus Helicopters), is designed for short range search and rescue operations. Secondary mission roles are patrol and observation, passenger transport, and cargo hook operations. It is capable of operating from prepared and unprepared areas in visual and instrument flight conditions, day or night and is configured with Night Vision Goggle (NVG) compatible cockpit lighting. The main sections of the fuselage are the forward section consisting of the cockpit, cabin area and baggage compartment, and the aft (tail boom) section. The forward section is constructed primarily of longitudinal, aluminum alloy beams and non?metallic honeycomb, laminated with fiberglass cloth. The aft section consists of a truncated cone of composite honeycomb fiberglass with a metal covering which supports the vertical fin and a fixed horizontal stabilizer. Cockpit entrance is through two hinged doors located forward of the cabin next to the pilot’s and copilot’s stations. Entrances to the passenger area are a hinged door on the left side of the cabin aft of the copilot’s station and a sliding door on the right side of the cabin aft of the pilot’s station. A baggage compartment door is located on the right side aft of the cabin for exterior access to the baggage compartment. The side?by?side cockpit arrangement is equipped with dual flight controls augmented by an Automatic Flight Control System (AFCS). Each station has a full instrument panel and controls for the avionics systems. Refer to figure 5?1 for general cockpit arrangement. The passenger?cargo area is designed to accommodate a rescue basket, litter configurations, and a hoist operator station. Seats may be installed for five passengers and a crew of three. The propulsion system, consisting of two turbo shaft engines and a drive system, is mounted above the fuselage on a platform located above the aft cabin area. The engines and drive systems are enclosed by a cowling which may be swung open or removed for access. The rotor system consists of a single 4?blade main rotor, which may be folded for shipboard parking or storage, and a multi?bladed shrouded tail rotor located within the vertical fin. Two independent hydraulic systems provide power for the flight controls, retractable landing gear, wheel brakes, and a 600 pound capacity rescue hoist. The electrical system includes dual AC and DC generating systems: two 10.5 KVA alternators to supply 400 Hz AC power (115V single phase), and two starter/ generators for 28 VDC power. In addition, each engine has a dual channel alternator to run its Full Authority Digital Engine Control (FADEC) computer. Electrical power can also be supplied by an internal battery or transformer/rectifier for emergency DC power, or AC and DC external sources. A Common Avionics Architecture System (CAAS) Avionics Management System integrates multiple communications, navigation and mission subsystems, automatic cockpit management, and flight guidance and control through selection of special sensors, and use of data stored in on?board Control Display Units (CDU). The Flight Director System (FDS) may be coupled to the AFCS to enhance airborne control of the helicopter. Additional equipment includes weather and search radar, an Environmental Control System (ECS), emergency pop?out flotation system, a 2,000 pound capacity cargo hook, and a controllable searchlight. The maximum unrestricted gross weight of the helicopter is 8,900 pounds. Restricted operations may be conducted up to a maximum weight of 9,480 pounds. Performance Objectives 1.Cooling: 3 or more Tons required , Airflow: 600 total CFM Desired. 2. Operating Environment: Normal operations: Outside: 103? F/50% RH. Cabin: 73? F/50% RH. The system must be capable of cooling avionics up to the H-65 maximum operating temperature of 122? F (50? C). 3. Design Details: 100 CFM cooled air directed into avionics compartment. The avionics cooled air will be supplied at 38? F desired, 73? F required. Separate temperature sensor and control for avionics compartment and cabin. Mixing duct with conditioned air, sensors and controls for cabin air temperature outlet 38? -170? F. Water separation. Low and high temperature protection (38?-170? F) Airframe equipment: air distribution system. 4. Weight: 35 lbs. desired, 100 lbs. maximum. Note: weight includes the heat/cooling unit and controls. Airframe ducting is calculated separately. 5. Size: 11.5 in x 28 in x 28 in desired. See attached depiction and CAD model of the current ECS compartment. Note: There is ducting, and other equipment located in the adjacent compartments. Closing date and time for receipt of response is October 16, 2024 at 12:00pm EST. Telephone responses will not be accepted. Responses should be submitted to alyson.s.harrison2@uscg.mil. Please indicate 70Z03825IB0000001 in the subject line.
