Re: Kaveri & Aero-Engine: News & Discussion

As someone pointed out, OEMs never start with a clean slate while developing a new engine. So in a co-development what is the fair share of work that Indian technologists can bring to the table? Where is the leverage here? I strongly believe that salvation still resides in pursuing Kaveri. GE and Sa...

Probably France is overconfident with their leverage with the existing Rafale jets, and the impending 114 jet sale. Engine selection will have a very direct impact on MRFA selection and maintenance. French may be least forthcoming, even though It is their opportunity to lose.

Certification of radar based weapons and the radome (re)certification/modifications will come to bite the Uttam. Better keep Uttam aside for next few years and let it mature. A half baked Uttam won't help with operational numbers, and HAL will use it as an excuse for any delays in delivery.
