- Description
- The Air Force Test Center (AFTC), Installation Contracting Division/PZIOAB, Eglin AFB Florida intends to solicit and award a sole source firm-fixed price (FFP) contract to Acutronic USA Inc., 700 Waterfront Drive, Pittsburgh, PA 15222-472. The proposed North American Industry Classification System (NAICS) code for the future acquisition is 334515 and its size standard is 500 employees. The following item(s) will be procured: CLIN Description Qty 0001 Hardware: High Speed Rotary Assembly (HSRA), High Speed Fiber, Gas, and Power (HSFGP) Assembly, refer to below technical specification requirements 1 each General Requirements The HSRA will be installed onto and become an integral part of various spinning electromechanical and electrohydraulic systems. The HSRA will be used to provide high pressure gas, electrical signals, and fiber optic signals continuously and simultaneously while rotating at maximum revolutions per minute (RPM) to laboratory items under test. The HSRA must be contained within a single, compact, lightweight package providing continuous 360 degree motion in both the clockwise and counter clockwise directions. The HSRA shall not require external cooling or lubrication for operation. The HSRA must produce smooth, stable and repeatable performance over the full range of RPM up to the specified limits and must provide reliable trouble free operation without the need for maintenance throughout its required service life. Dynamic Performance All specifications apply equally for clockwise and counter-clockwise motion. a. Maximum Rotational Speed: 2500 RPM b. Maximum Rotational Acceleration: 120,000 degrees/second/second c. Repeated bi-directional rotation from zero (0) RPM to two thousand five hundred (2500) RPM at 120,000 degrees/second/second without damage or degradation in performance. d. Provide sustained operation at 2500 RPM (objective), and for the anticipated duty cycle in Section 2.5 (threshold). Physical Size and Weight The HSRA shall be contained within a single, compact, lightweight package. Emphasis should be placed on reducing weight and physical size together without compromising performance. An example of a desirable package is one measuring less than 6" long by less than 4 inches in diameter and weighing less than 4 pounds. Compatibility with Spinning Assemblies The HSRA shall be compatible with and capable of being installed onto/into existing facility electric and hydraulic spinning assemblies. Mechanical interface specifications are available upon request. Cabling a. Electrical conductors shall be shielded single conductor, stranded tinned wire, with insulation which does not absorb oil, is not harmed by prolonged oil contact and does not separate from conductors at sustained maximum rotation rates. b. Fiber optic conductors shall be single mode fully jacketed with a jacket which does not absorb oil, is not harmed by prolonged oil contact and does not separate from conductors at sustained maximum rotation rates. Anticipated Duty Cycle The anticipated duty cycle will typically be twenty (20) test cycles in ten minutes of use followed by a six to ten minute rest over an 8-12 hour day. A single test cycle takes approximately 30 seconds and consists of: a. Acceleration at 120,000 degrees/second/second from zero to 2500 RPM and holding at this RPM for 5 seconds; b. A period of modulated speed between 1500 to 2500 RPM for 15 seconds; c. A spin-down to zero RPM lasting for 5 seconds; d. Stopped for 5 seconds. Design for Maintainability The HSRA shall be designed for ease of routine user performed maintenance, repair, and replacement of the gas, electrical, and fiber optic subassemblies and their wear components. Wear elements shall be field replaceable with minimal disassembly and without special tools. Required Service Life The HSRA and its subassemblies shall provide a service life of greater than or equal to thirty million (30,000,000) revolutions before requiring routine maintenance or replacement of wear components. System Components Quality and Lifespan All components shall be of a manufacturer/model having a well-established U. S. track record for dependability, durability and trouble free operation in an industrial environment. Due diligence shall be performed to ensure no components are used that are nearing the end of their manufacturing life cycle or are scheduled for revision. Component Spares One set of component spares containing normal field replaceable wear elements for each subassembly shall be provided. Documentation A complete set of HSRA documentation shall be provided including final electrical and mechanical drawings, user manuals, operation and maintenance manuals, and commercial off-the-shelf (COTS) equipment manuals. The documentation shall be in electronic form compatible with Microsoft Office products with at least one full set of documentation in printed form. Warranty A one year parts and labor warranty for all parts and components of the HSRA system shall be provided. Technical Support Technical support in the form of two years of hardware technical support via phone and/or email shall be provided. Nitrogen Gas Subassembly Specifications The HSRA shall contain a rotary gas subassembly possessing the following characteristics: a. Continuously supply 3,500 psi (Threshold) 6,000 psi (Objective) high purity nitrogen, argon or Freon gas to the test unit. b. Contain no elements that will contaminate the high purity gas supply. c. Shall terminate on the stationary end of the HSRA into a ruggedized flare type connector installed onto the HSRA housing. d. Shall terminate on the rotary end of the HSRA into tubing three (3) feet in length. Electrical Slip Ring Subassembly Specifications The HSRA shall contain an electrical slip ring subassembly with the following characteristics: a. Provide full rated voltage and current for all circuits simultaneously with sustained operation at 2500 RPM, for the expected duty cycle in Section 2.5, and for intermittent use to the maximum rotation rate. b. Contain, at a minimum, the following circuits: a. Sixteen (16) circuits rated ten (10) amps at sixty (60) volts RMS. b. Two (2) separate shield circuits with no more than eight (8) conductors grouped to a single shield circuit. c. Slip ring noise shall be no more than 0.4 millivolts at one (1) amp and twenty (20) revolutions per minute. d. Minimum sixty (60) dB isolation at 1 kilohertz between any two rings to minimize crosstalk. e. No more than sixty (60) milliohms (Threshold) ten (10) milliohms (Objective) resistance across the brush/ring connection. f. Shall terminate on the rotary end of the HSRA into a flying lead three (3) feet in length. g. Wiring shall be terminated on the stationary end into an industrial rated twist lock connector installed onto the HSRA housing and containing pin contacts. h. Conductors shall be sixteen (16) gauge or larger. Fiber Optic Subassembly Specifications The HSRA shall contain a fiber-optic (FO) subassembly with the following characteristics: a. A single fiber commercially available single mode fiber-optic rotary assembly capable of full bandwidth single mode operation. b. Shall terminate on the stationary end of the HSRA into a ruggedized FC type fiber optic connector installed onto the HSRA housing. c. Shall terminate on the rotary end of the HSRA into a flying lead three (3) feet in length. d. Shall deliver stable signal amplitude through the assembly that does not vary more than 10% in signal amplitude throughout the full rotational speed of the assembly. The estimated delivery time is 6 months after receipt of order under contract #FA2823-15-P-0067. This purchase will be for the 782 TS/RNWG. Anticipated award date is August 2015. This notice is not a request for competitive proposals/quotes. However, the Government will consider all responses received no later than 10:00 a.m., Central Time, 5 August 2015. A determination by the Government not to compete this proposed purchase based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Contractors interested in this requirement should submit a technical package, which provides clear and convincing evidence that they can meet the Government's requirement. In addition, the response should include any special requirements for a commercial contract (i.e. Commercial Financing, Warranty Provisions, Delivery Information, etc.) in accordance with Far Part 12. Questions shall be submitted electronically to the following: Juliet.hall@us.af.mil (Contract Specialist) Willis.crouch@us.af.mil (Contracting Officer)
