Boeing 767 Trailing Edge Flap Drive Test Stand
This trailing edge flap drive is a rotary actuator with planetary gearbox and an integral torque limiter.
The test stand uses a VSD electric motor to drive the actuator while a hydraulically actuated rack and pinion oscillator provides dynamic loading and no-back torque drive. Input torque is measured by an inline rotary torque sensor. Output torque is measured by a hollow reaction torque sensor.
All data such as torque, speed, lockup torque and mechanical efficiency are automatically recorded by the Opto 22 data system. A PC workstation provides the GUI.
Test procedure may be run automatically or may be done individually in semi-automatic mode. Test reports are generated automatically or on demand and feature pass/fail notification.
