BEIJING: China has built a potent military machine over the past 30 years but is struggling to develop advanced engines that would allow its warplanes to match Western fighters in combat, foreign and Chinese industry sources said.
The country's engine technology lags that of United Technologies unit Pratt & Whitney, General Electric and Rolls-Royce, said Douglas Barrie, senior fellow for military aerospace at the International Institute for Strategic Studies in London.
China's Defence Ministry, in a brief statement to Reuters, said there was a "definite gap" between Chinese military technology and some developed countries, adding Beijing would continue to strengthen its armed forces.
Western restrictions on arms exports to China prohibit the sale of Western engines for military use, forcing China to rely on homegrown designs or engines Russia has agreed to sell.
"Chinese engine-makers face a multitude of problems," said Michael Raska, assistant professor in the Military Transformations Programme at Singapore's S. Rajaratnam School of International Studies.
Among the issues, China's J-20 and J-31 stealth fighters cannot super-cruise, or fly at supersonic speeds like their closest rivals, Lockheed Martin's F-22 and F-35 stealth planes, without using after-burners, said two industry sources who follow Beijing's military programmes closely.
After-burners remove a warplane's stealthiness, a capability that allows them to escape radar detection.
Even the warplane engine that experts consider to be China's best has reliability issues, said the sources, who declined to be identified because of the sensitivity of the matter.

Which is why gearbox and turbine engine technology is restricted just like actual armaments.
Super cruise and supersonic are overrated.
Supercruise/supersonic is needed to get to somewhere, but if you have enough fighters then they are already there.
You can’t fight at supersonic speeds, so that’s out.
The price of these fighters is getting far higher than missile technology for far cheaper.
I wonder how reliable the Ukrainian gas turbines are.
If Hillary gets in office, whe will continue Bill’s practice of selling military technology to the Chicoms.
Why not just make a large donation to the Clinton Foundation?
Ping
If Hillary is elected she will fix this.
What a load of bull.How difficult would it be for the Chinese to buy or steal an engine or the blueprints for an engine that would be used by the f22 or f23.Not difficult at all.
I don’t see the problem here. The Clinton Family Foundation is open for business and special sales are always on.
Blueprints are one thing...
Think of all the Chinese knockoffs you’ve encountered.
Stand back safe distance.
Whatta laff.
Listen, the original design equations for gas turbines were written up by Chung Hua-Wu when he was in the U.S. in the 1950’s working for NACA.
His method for axisymmetric throughflow analysis is what GE and Pratt used for decades. It has only recently been replaced by viscous flow Navier-Stokes solutions.
But most of the grad students writing that stuff are um...Asian. And they got no problem going home and taking what’s in their brains with them. Or selling it on the open market.
Wu was like Tsien: he went home when the U.S. refused him a clearance in the 1950’s. He founded their jet engine industry, and it continues to this day.
Only a matter of time before they get on par between free trade, free immigration, and the decline of American manufacturing and education at the hands of the trash that opened our borders and holds Americans in contempt.
Personally I try to avoid anything that is manufactured in China because the Items are usually lower in quality and dependability but you can’t even buy an IPhone that’s not made in China.
How far America’s production capability has fallen.
I wonder if the engines they get from Russia are monkey models.
Hillary will sell it to them — if Barack doesn’t beat her to it.
That in itself isn't enough - the real challenge is the manufacturing/heat-treating of the first-stage turbine blades.
It’s not the design or the blueprint the ChiComs really need. They probably already have those. It’s the metallurgy that they lack. Jet engines have some really exotic metals and if you don’t have all that knowledge making parts durable and flexible at the same time the engines will implode and break into little hot, extremely sharp pieces of shrapnel.

Reliability is only part of the equation - it's power to weight ratio, or actually power turbine outlet temps - how hot can it run without the PT blades melting...
(I've had a few blow while under throttle - it's not a pretty sight)
A China uncensored YOUTUBE. About two minutes in, China can not make a powerful enough engine to fly off a carrier.
If she's somehow stays out of jail and gets elected, this sort of stuff just might get her family foundation a big Chicom “donation”.
