Key Points
A discussion with General Electric (GE) Aerospace, which started in 2012 over transferring 58 per cent technology to India for manufacturing jet engines, eventually took shape Thursday, with the former agreeing to transfer 80 per cent of the technology instead after hectic negotiations in the last few years, a top defence official said Friday...
As per the official, the 12 key technologies offered included special coatings for corrosion, erosion and thermal barrier for hot end, machining and coating for single crystal for turbine blades, machining and coating of nozzle guide vanes and other hot end parts, and blisk machining..
The technologies offered also include machining of powder metallurgy discs, machining of thin-walled titanium casing, friction/inertia welding for fan and after burner, polymer matrix composites for bypass duct, machining and coating of ceramic matrix composites for nozzle guide vanes and flaps, laser drilling technology for combustor and bottle boring of shafts...
Defence officials said that out of these, GE has offered complete transfer of technology for special coatings for corrosion, erosion and thermal barrier for hot end, laser drilling technology for combustor, bottle boring of shafts, blisk machining, machining of thin-walled titanium casing, friction/inertia welding for fan and after burner and for polymer matrix composites for bypass duct..
Similarly, earlier when GE was to transfer 58 per cent technology, only machining was offered for single crystal for turbine blades, machining and coating of nozzle guide vanes and other hot end parts, but now coatings have been added as well..
