A. Background The Fabrication Division’s provides valuable service balancing services for agency and center level programs. They include Advanced Air Transport Technology NASA Electric Aircraft Testbed (N.E.A.T.), Quiet Spacecraft Cabin Ventilation Fan, Revolutionary Vertical Lift Technology (RVLT) Icing Research as well Reimbursable GE Aviation’s work.

The actuals balance hardware system which is still is end very good condition however the control system is some 40 plus years old and has long reached the end to it life cycle. Most parts any no longer manufactured. This makes repairs and spare parts increasing difficult to obtain. This are usually causing delays or equipment availability. This has impact schedule for the project that are being supported.

The Fabrication Division plan to replace two Cab 690 Measuring Unit with a SCHENCK MODEL CAB 925 Instrumentation Unit. Each controller are use for a SCHENCK TREBEL CORP. Model Number: HQ5UB, Serial Number: AHG0095 and a SCHENCK TREBEL CORP Model Number: HQ5UB, Serial Number:

AHG0095. The Cab 690 unit is a dual control unit able to control both balancers with increase capabilities.

B. Deliverables

• One (1) SCHENCK MODEL CAB 925 Instrumentation, to included Vector and numeric display, Measuring dynamic unbalance in 2 planes, static unbalance and couple unbalance, Automatic tolerance comparison, Polar display or in equally/ unequally distributed components, Averaging of the measured values over time rotor type-related, Tolerance calculation according to ISO 1940, drive control for automatic measuring cycle, Monitoring measuring signals, at least touch screen Active 15" TFT color display with high luminosity, Speed range at of least 100 to 5,000 rpm, optional 40 to 100,000 rpm, USB for peripherals Interface with Customer configured -specific report, Averaging over runs/marking of values, Electronic protractor for angle indication, Extensive balancing corrective software, e.g. milling, applying weights, Overlapping cycle, Rotor-specific calibration, Measurement during runup with marking, Averaging over runs, Vibration velocity measuring mode with single and double (2f) reference frequency, Additional measurement channels for runout measurement, Printer, Two Machine operation

• One Day for commissioning of the instrument and operator training and Online Fundamentals Training

• To included Single Compensation Software - is used to null out residual unbalance prior to running a rotor assembly with an additional rotor stage. Biasing is also useful for troubleshooting balancing problems.

• To included Index Balancing Software to compensate for residual unbalance and eccentricity of tooling. This option is required for setups employing rotating balancing tooling.

• To included Phase Reference Generator, with extension cable and two (2) pickup cables.
