Engines commonly used in Chinese and other modern aircraft may be divided into several major categories: (1) low-bypass turbofans typically power military jets; (2) high-bypass turbofans typically power jet airliners; (3) turboprops typically power more fuel-efficient, usually lower-speed aircraft, including civilian commuter aircraft and military transports and surveillance and battle management aircraft; and (4) turboshafts typically power helicopters. This study will address the first category, low-bypass turbofan engines; other categories will be addressed in follow-on China SignPost™ reports.
–China’s inability to domestically mass-produce modern high-performance jet engines at a consistently high-quality standard is an enduring Achilles heel of the Chinese military aerospace sector and is likely a headwind that has slowed development and production of the J-15, J-20, and other late-generation tactical aircraft.
–The Chinese aerospace industry is driven by four key strategic imperatives as it pursues the ability to manufacture large volumes of high-performance tactical aircraft engines: (1) parts dependence avoidance, (2) Russian supply unwillingness, (3) aircraft sales autonomy, and (4) poor Russian after-sales service.
–To address these shortcomings, AVIC is treating engine development as a high priority and plans to invest 10 billion RMB (US$1.53 billion) into jet engine research and development over the next 5 years.
–However, evidence still suggests that AVIC’s engine makers are having trouble maintaining consistent quality control as they scale up production of the WS-10, causing problems with reliability and keeping China’s tactical aircraft heavily reliant on imported Russian engines.
–Key weak points of the Chinese military jet engine industry include: turbine blade production and process standardization.
Here it goes, both China and India have to cross lot of miles before a good engine can be mass produced. From Indian stand point, we need to cross little more in terms of materials and manufacturing techniques. China's programs have started little early then us. But I give India a better chance of reaching the maturity state earlier, because of access to better technologies and nations ready to sell some techs.
There is no doubt China will EVENTUALLY overcome its engine deficiencies. It is just a matter of time. The question is how much time and how far behind the West will they be when they finally figure it out. They are still trying to perfect 70s era engines.
Why are we so afraid to compete with China? We should throw them an open challenge so that we can push our selves harder, does not matter who loses or wins, what matters is that we got an opportunity to give our 100% effort.
Both India and China have the necessary technical strength to go in for developing a high performance jet engine. But as we have seen that it is easier said than done. Money alone does not guarantee a good engine. It is a tough path and I am sure that in a short period of time we will see an engine from both the countries.
True, but I have a feeling India can "buy" some of the tech from it's defense deals and learn from that. If India is willing to pay for the IP through their defense deal offsets, then no need to reinvent the wheel for everything. As long as the seller knows that they are selling a part of the know how along with the tech, it is all above board.
China shot themselves in the feet when they bought a few engines from Russia and tried to copy them on the sly, thereby pissing off the Russians and scaring off the west. Otherwise China could have had their completed engine technology by now.
This is where I like the Chinese approach much better than India.
Rather than the product and buying it, they focus on its technology. Regardless of self researched or stolen, what matters is they eventually learn and are able to make the product on their own.
In long run this would be one of the big differences between India and China unless India takes the que and improves.
