This invention relates to the development of a novel method to coat wear resistant material on gas turbine engines parts. In gas turbine engines, there are components such as gears, bearing seats, bushes etc., that act as a seating for different shafts which rotates at very high RPM which requires high wear resistan...

Lapping of top loaded flank of the blade is very important to improve the load sharing by the root lobes. Failure of the turbine blades normally occur due to top serration loading and to obviate the lapping of blade root are introduced which ensure that all serrations touch and share the load under the engine runnin...

This invention relates to the development of a novel method for preparing an aluminium silicon powder for giving protective diffusion coating on gas turbine engines parts operating in medium and high-temperature operating environments. In gas turbine engines, there are components such as turbine blades, discs, liner...

This design innovation is on integrating the Oil pump assembly of gas turbine engine with novel gasket to avoid leakage. The oil pumps made in light alloys, having plate stack up configuration, leaks at mating interface. The leak is observed mostly after few hours of servicing, raising a serious reliability issues, ...

There is a serious issue of failure of, "Attachment Screws", integrating the axial diffuser vane segments with the casing, on the aero engines operated in corrosive or saline atmosphere. There are number of cases reported on gas turbine engines, where it is observed that the attachment screws are getting sheared off...

Metallo ceramic composite coatings are being used on certain hot end components of jet engines for imparting dry wear resistance. Some of the engine components were sent to Original Equipment Manufacturer (OEM) sources for coatings like cobalt chromium carbide coatings. Deposition of such composite requires equipmen...

In the aerospace industry, as in many other industries, there is currently a strong interest in maximising the utilisation of existing assets. Hence there is a strong need on maximum utisisation of the engine as a whole and to" know any spares capacity can be exploited. From the perspective of aero gas turbine engin...
