Re: Upgrades in Jf-17
Its not that easy to just find another engine... it has to fit into the aircraft's airframe, as well as be compatible with the aircraft's interfaces.
I think the way the JF-17 is designed, only Chinese and Russian engines would work. And there is NO POLITICAL problem with the current Russian engine. TRUST me. The Chinese knew long ago that India would try to block the export of JF-17s with RD-33 to Pakistan.
The Chinese were well aware with this, and TOLD the Russians that the RD-33 WILL go to Pakistan, or the Chinese simply won't buy the engines from Russia. Russia, in desperate need of money agreed. The RD-33 is gonna be used, whether India likes it or not. China KNOWS this. There is a strong chance that the JF-17 will be used ONLY by the PAF in the world, and without an engine, all the money invested in the project by China would be lost. So why would they invest so much time and money into a project that would never be used? They have it covered.
And in case of some wierd reason the Russian engine fails, the Chinese HAVE reverse engineered it, and have their own versino for use.
The thrust to weight ratio of 0.95 to 1 isnt that impressive, but then again the Tornado, F-18 and even Gripen don't have a 1:1 ratio. So its not that bad.
