Description

The Naval Air Warfare Center Weapons Division, China Lake intends to procure on a competitive basis, an additional yaw arm and roll fixture for an existing 5-axis Carco Electronics Flight Motion Table (Model S-690R-5). The requirement includes design, fabrication and integration, which includes controlling electronics, software, cabling, installation, calibration, acceptance testing, documentation and a one year warranty. The new roll fixture will include collets for units under test with 8", 10", 12" and larger diameters. The diameter of the unit under test, and thus the roll fixture itself, has a direct bearing on the maximum yaw axis angle. The yaw axis must be able to achieve an unobstructed + 45 degree displacement and leave a clear field of view + 5 degrees from center of roll axis. It is desired to have the roll fixture accommodate units under test as large as possible, up to 14" if possible, but no less than 12.5". The diameter of the roll fixture also impacts where the unit under test meets the axis of intersection of the pitch and yaw gimbals. The following are general specifications pertaining to the performance of the new roll fixture and associated control mechanisms: a) Maximum length of unit under test -- 30"; b) typical payload weight -- 80 pounds; c) typical payload inertia -- 3.9 in-lb-sec2; d) maximum acceleration -- 6000 degrees/sec2; e) maximum velocity -- 300 degrees/sec; f) maximum roll angle displacement -- + 180 degrees; g) resolution of roll displacement -- 0.036 degrees; and h) frequency response at 90 degree phase -- 20Hz. Installation of the new roll fixture and associated control electronics and software must not interfere with the use of the existing roll fixture. The exchange of the old and new roll fixture must be able to be accomplished with existing in-house equipment and technical personnel. Documented procedures must be supplied to aid in making the change. The new roll fixture must use the existing yaw actuator hub and bolt pattern as its point of mechanical connection with the existing system. Hydraulic power lines are in place for use by the new roll fixture, if needed. If not used, the hydraulic lines must be situated to maintain hydraulic system integrity when the new roll fixture is in use. Installation of additional cabling must be minimized as it may impede performance. As part of the integration of the roll fixture, and associated control software, a new high-speed data interface must be included. This interface may take the form of a reflective memory scheme that uses a common industry protocol such as ScramNet or Bit3. The contract will be procured utilizing Best Value Source Selection. A site visit will be scheduled after release of the solicitation. Details of the site visit will be provided in the solicitation. Award is anticipated in August 2001. A request for proposal (RFP) will be posted and available electronically on or around February 12, 2001 at the following Internet site: http://www.nawcwpns.navy.mil/~contract/rfp-nawc.htm. All responsible sources may submit a bid, proposal or quotation, which shall be considered by the agency. See Numbered Note 26.
