Name the technologies we are currently lacking that will take 25 years to develop.
Single crystal blades and thermal barrier coatings for starters. Technology that took Pratt and Whitney, and GE how many years to develop? Not talking about TS1400. Plus various other small tidbits, Mr. Mahmut Akşit himself said that they faced embargoes on fuel pumps, oil pumps, gearboxes, etc.. and that this has caused delays. I don't know which parts we can manufacture and cannot, but I'm just realistic enough to know that making an engine of that scale without outside help is not realistic.
What did it take for China to come up with WS-15? For India to come up with the failure that is Kaveri? What is the total budget for our TF-X project? Don't dodge this question now.
Don't get me wrong. I, too, am very keen on getting RR for engine development. It would be a guaranteed solution and would be utilized in a shorter time than an indigenous engine. But we should develop our engine regardless of RR's involvement.
We should definitely develop our engine. But the TF-X engine, has to be built in the near future. Which is why we NEED that involvement. Because otherwise that shorter time window will be about at least 20 years. You should accept the fact that our armed supersonic stealth jet meeting the enemy in the sky with our indigenous engine of >30,000lbfs after all the development and testing periods will need no less than that.
Also, the problem in the Altay tank was the engine and transmission, it was to be imported from abroad, it was planned like this. We already had the ability to make the shell of the tank. But MMU also has an engine claim, it's not the same thing.
The Altay tank was a real serious project for us, since we couldn't procure any more tanks due to the embargoes. Yet, it was far less complex than a turbofan, yet since 2007 a single tank is yet to be produced. How much more money and time needs to be sunk before we get to replace our aging tank fleet? And the thing is well obsolete, before it has come out yet. Looking at this, the far more complex task of developing a turbofan wholly indigenously? ..Yeah. As for your previous post, you can only crush so much money until you're broke. As for our friends so called "support", it will end up same fate as the Altay. No thanks. I do pray that the cooperation does not fall apart because if it does, with that other thing going on which I will not mention, we'll have a real predicament in our hands.
