Description
Digital Turnover Tool (DTT) is designed to improve the efficiency of aircraft engine borescope inspections by automating the process of rotor shaft positioning.
The DTT provides greater efficiency than manual turnover by eliminating the need for a second technician to rotate the engine shaft. The DTT also provides a constant rotation speed, overshoot-free operation and automatic blade counting, all of which are unattainable with manual turnover.
There are three major components to the DTT system: the controller, the power unit, and the drive unit. All engine inspection functions reside on the controller, with a second user interface housed on the power unit.
Click on downloads for a complete list of engines served and available components.
Benefits:
- Reduced manpower eliminates the need for an additional person to hand crank the engine
- Reduced inspection time, automatic vs. manual
- Improved quality of borescope inspection
- Easily relocate damaged blades
- Electronically stored inspection reports
- Printer interface via serial communications port
- Electronics that can be easily updated in the field
- Easily adapted to various engines
- Power unit will accept shop or aircraft electrical supply voltage
- Quick installation and hook-up
- These tools can be operated by a single person
