3、his commercial item description (CID), for all federal agencies. 1. Scope. This commercial item description covers a permanent back shop test stand designed to check the function of linear and rotary electro-mechanical actuators. The test stand should be capable of interfacing with 42 different actu
4、ators from seven different aircraft (C-5, C-141, F-15, F-16, KC-135, T-38, and T-39). The LREATS should be capable of accommodating the size, stroke length, physical mounting interface, and electrical connectors of each actuator. The LREATS should also be able to supply the correct power input type
5、and the precise amount of resistance to motion required for each individual actuator. 2. SALIENT CHARACTERISTICS. 2.1 Design. The LREATS design shall consist of a linear test stand (LTS), an instrument test stand (ITS), and a rotary test stand (RTS). 2.1.1 Linear test stand (LTS). The LTS shall be d

The RTS shall be designed with an independent control panel which will be mounted onto a swing arm and shall provide the means to control and monitor the operation of each load system as well as torque and speed of the UUT. The RTS shall be designed with
12、a rotary test load fixture that includes two adjustable mounting facilities to test rotary devices. One of the two lighting facilities shall be capable of applying and measuring a 5 inch-pound torque (in-lbf) load and 0 - 25.000 rpm input. The second mounting facility shall be Provided by IHSNot for

The ITS shall provide complete instrume
16、ntation for reading the results of the RTS and LTS. The ITS shall interface with the RTS and the LRS. The ITS shall provide means of energizing or de-energizing the system panels. The ITS shall provide complete instrumentation for controlling and monitoring the LTS and the RTS. The ITS shall have a
17、28 volts direct current (DC) section and connection in order to provide power to UUT when required. The DC section shall have display that will indicate when the DC circuit is activated, as well as display voltage and current reading. The ITS shall have an alternating current (AC) section and connec
18、tion provide 208VAC, 400 Hertz (Hz) power to the UUT. The ITS shall have the ability to adjust the AC voltage to the desired levels by the operator. The AC section shall have a display that will indicate AC voltage, current and power to the user. The AC sections shall allow for forward, reverse, and
19、 limiting actuator motion controls. The AC section shall provide indicator information for the UUT phase characteristics.
