Description

Sources Sought Notice: The Air Force Flight Test Center (AFFTC), Edwards Air Force Base, CA is seeking potential sources capable of providing thirty (30) Wheel Speed and Hubcap Assemblies. The assembly consists of the items as listed: 30 each Wheel Speed Transducer, and 30 each Hubcap. The function of the entire assembly is to sense wheel speed at landing to prevent skid on a runway by communicating with an on-board control unit that monitors brake application pressure. Other salient characteristics are described below: Two wheel speed transducers provide individual wheel velocity measurement for each of the braked wheels. The transducers have axle adapters to allow them to be mounted inside the axles. The transducer-adapter assembly is secured by threaded fasteners protruding through the axle and castellated wheel axle nuts. The transducer shaft extends from the transducer toward the hubcap. On the shaft a drive coupling is installed, which is driven by the hubcap drive mechanism. The field-proven hubcap-transducer drive interface is of sufficient rotational stiffness and strength to prevent transmission of erroneous wheel speed velocity signals. The coupling design can accommodate angular and parallel misalignment and axial assembly tolerance without degradation such as premature bearing or drive coupling wear. The transducer is a variable reluctance alternator with 36 polies (teeth) on the rotor with 36 matching poles (teeth) on the stator. The magnetic field is provided by a coaxial coil energized by the control unit transducer bias current. With the excitation applied, a static magnetic field is established between the north and south poles of the rotor, air gap, stator and return path iron of the transducer, and no output is produced. As the wheel rotates, rotor teeth pass the stator slots and teeth, causing variations in the reluctance of the magnetic circuit, which causes a change in the flux linking the coil. The transducer output is, therefore, a sinusoidally varying voltage, with a frequency directly proportional to wheel rotational velocity. Transducer Weight: The weight of the wheel speed transducer is 1.1 pounds. The weight will be further defined after final axle adapter design. The transducer weight does not include the weight of the hubcap, which is included in the total system weight estimate. Please note that this synopsis is for planning purposes only and does not constitute a solicitation for competitive bids/proposals and is not to be construed as a commitment by the Government. However, all interested parties who believe they can meet the requirements are invited to submit in writing complete information describing their ability to provide complete Wheel Speed and Hubcap Assemblies listed above. Firms responding to this synopsis must identify their company’s capabilities to perform the requirements described herein, reference the synopsis number and indicate whether or not that they are a small or small disadvantaged business concern as defined in FAR 52.219-1. The NAICS code is 336413. The Small Business size standard is 1000 employees. The information received as a result of this notice will be considered solely for the purpose of determining whether to conduct a competitive procurement. A determination by the Air Force not to open the requirement to open competition, based on response to this sources sought synopsis, is solely within the discretion of the Air Force. The Government does not intend to pay for any information provided under this sources sought synopsis. It is anticipated that a Firm Fixed Price contract will be awarded in Jan of 2006. All responses may be sent via e-mail to Philip.cheng@edwards.af.mil or mailed to 412 TW/PKDB, 5 South Wolfe Ave, Edwards AFB, CA 93524-1185, Attention: Philip W. Cheng. Fax Number: 661-275-7827. Responses to this sources sought synopsis are due in the office by Close of Business (COB), 9 Dec 2005. NOTE: THIS NOTICE WAS NOT POSTED TO WWW.FEDBIZOPPS.GOV ON THE DATE INDICATED IN THE NOTICE ITSELF (25-NOV-2005); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE. PLEASE CONTACT fbo.support@gsa.gov REGARDING THIS ISSUE.
