Development of Laser-based Tools Techniques for Turbine (GT) to Reduction Gear (RG) and RG to Shaft Alignment.

Currently, the conventional methods (mechanical dial gauge) are being used for alignment of GT to RG and RG to shaft line on-board IN warships.

This technique has a number of significant drawbacks including-

• Conventional methods are tedious and time consuming which require multiple iterations and are inefficient.
• During capture of readings, no concurrent work can be progressed in Engine Room.
• Special tools required for carrying out alignment are nonstandard and different across all platform/ ships.

Future Expectation from the prototype / Technology developed

The laser-based GT to RG and RG to Shaft Line Alignment tools/ techniques should be able provide a universal solution to overcome the existing issues experienced while using the conventional methodology.

The results will be more precise and able to capture sufficient readings to avoid multiple iterations.
