- Description
- The Naval Surface Warfare Center, Carderock Division (NSWCCD) is issuing a Request For Information (RFI) from all potential sources who may have technologies or systems relating to the design, production, and repair / overhaul of single reduction right angle drive gearboxes that may be integrated into the Landing Craft, Air Cushion (LCAC) transmission system. Each craft contains a port and starboard machinery system. Each machinery system consists of two (2) gas turbine engines with one single reduction right angle drive gearbox for each engine (total of four (4) gas turbine engines and four (4) single reduction right angle drive gearboxes per craft), as well as shafting sections, flexible couplings, and parallel axis single reduction gear drives that transmit power to the lift and propulsion systems. Each gas turbine engine delivers 4,000-5,000 SHP @15,400-16,100 RPM. The right angle drive gearbox must reduce the engine output shaft speed by a factor of 2.76, such that the maximum gearbox output drive shaft speed does not exceed 5,833 RPM. On each side of the craft, the forward most right angle gearbox must be connected to a manually operated disconnect clutch. Gearbox designs must be able to handle a maximum continuous torque (from the gas turbine engine) of 1,565 lbs ft. All gearbox designs must incorporate an overrunnin g clutch to allow for continued operation of the lift and propulsion systems in the event of an engine shutdown. The total wet weight of each right angle gearbox must not exceed 340 lbs. Potential gearbox designs must not exceed the following dimensional constraints: length (parallel to craft centerline including gearbox drive shaft) = 27 in, width (athwartship) = 20 in, and height = 22 in. All gearbox designs must be able to operate with MIL-L-23699 (synthetic) oil. Each gearbox must incorporate a debris monitoring device (chip detector) to detect and electronically transmit wear metal information to the operator. Gearbox designs must conform to MIL-STD 271F Change Notice 1 (non-destructive inspection) and MIL-STD 167-1A (vibration). In addition, all gearbox designs must be certified in accordance with ANSI/AGMA 6032-A94 and ANSI/AGMA ISO 1328 (accuracy grade 2 to 3) for high speed marine gears, and the gearboxes must have a designed MTBO of 6,000 hours. This RFI does not bind the Government to offer contracts to responding companies. The information provided will assist NSWCCD in the development and refinement of future procurement and acquisition strategies. Defense and commercial contractors, including small businesses, veteran-owned businesses, service-disabled veteran owned businesses, HUBZone small businesses, and woman-owned small businesses are encouraged to participate. Responses Responses to this RFI should include supporting materials that details experience, competence, and an overall understanding of the requirements that NSWCCD has identified. The following information is requested (please indicate whether the provided information is estimated or actual): 1) a description of the gearbox, 2) the development timeline, 3) the non-recurring engineering costs, 3a) unit production cost estimates identified for the gearbox options, and identify sensitivity of production cost to volume of sales (quantity discounts), 4) minimum annual reduction gearbox purchases to sustain production, 5) gearbox heat rejection estimate, 6) horsepower losses, 7) gearbox dimensions, 8) gearbox weight, 9) technical constraints that are driving the ability to provide a gearbox or adding risk in terms of technical or schedule performance, 10) plan for repair and overhaul of gearbox components as necessary during craft lifecycle. The NSWCCD Power Transmission Branch (NSWCCD 9320) requests your responses no later than 30 April 2008. E-mail information to Mr. James Lambert at james.lambert@navy.mil, NSWCCD 9320, 1000 Kitty Hawk Avenue, Philadelphia Naval Business Center (PNBC), Philadelphia, PA 19112 labeled with the solicitation number and LANDING CRAFT, AIR CUSHION (LCAC) TRANSMISSION REDUCTION GEARS. All questions may be submitted electronically to james.lambert@navy.mil. All information provided will be treated as Business Sensitive and will not be shared outside of Government activities and agencies without the permission of the provider. All information shall be provided free of charge to the Government. NSWCCD may request further information regarding the capabilities of respondents to meet the requirements, and may request a presentation and / or site visit as deemed necessary.
