 Purpose and Capabilities The aircraft generator test stand is designed to test the operation and performance of 28-volt and 120-volt d-c genera-tors and 120-volt, 350 to l00 hertz, single-phase, a-c generators which are used in aircraft electrical Systems. Skids are provided on the frame to permit movement of the unit from one site to another. The unit is manufactured in accordance with Specification MIL-T-6333A. 1-5 General Description The generator test stand consists of a variable speed drive with related electric drive motor and a speed actuator or changer; a control panel to monitor and control operation; a load bank with resistive load units, cooling fan and contactors; and electric motor-driven blower with duct work for generator cooling; Contactors are pro-vided for motor starting as well as current trans-formers and circuit breakers for circuit protection. Components are supported and located on the welded steel, cabinet type frame which is provided with skids for transportation. Removable panels are provided for access to enclosed components. 1-6 Variable Speed Drive The variable speed drive is a reversible, motor-driven variable speed transmission contained in a cast iron housing mounted on the frame. The drive is a double belt type operating through four variable pitch pulleys, two on the lower drive motor shaft and two on the upper intermediate shaft. Gearing connects the inter-mediate shaft to high and low speed output shafts which are located at the generator mounting faces. The front (high speed) position range is from 3000 to 11600 rpm and the rear (low speed) position range is from 2350 to 9000 rpm. The speed of the output shafts with speed ratios of 6.21 and 4.92 to 1, is varied by changing the pitch diameter of the pulleys as regulated by the speed changer. Output shaft rpm is read on the tachometer at the control panel.  US Varidrive, HP: 30, PH: 3, Volts: 220-440,  Type: VEU-GS-DT, RPM Min: 3000 RPM Max: 9000, Frame: 53-404-1-5 Code: f, Design: B, Gear Ratio: 3.517-4.250 Serial: 2252439, Cycles 50 - 60, Motor RPM 1500-1800, HP Amps 55-46, Hi Volts 110 Lo Volts: 92 Item Dimensions W: 30" D: 55" H: 37" Weight: 3000 lbs.  I CAN HELP ARRANGE FREIGHT SHIPPING AT BUYERS EXPENSE, FREE FORKLIFT LOADING AT SITE.
