The new J-20 strike fighter program (first unveiled during Defense Secretary Gates’ January 2011 visit to China), especially needs domestic engine development and production breakthroughs because Russia appears reluctant to sell the high-powered engines that could enable the J-20 to supercruise (sustain supersonic flight without using inefficient afterburners) and thereby match the performance of the world’s most modern fighters such as the Lockheed Martin F-22 and Sukhoi T-50/PAK FA. Such developments would help cement China as a formidable regional air power and deserve close attention from policymakers.
However, evidence still suggests that China’s main military jet engine maker—Aviation Industry Corporation of China (AVIC)—is struggling to maintain consistent quality control as it scales up production of the WS-10 Taihang turbofan that China hopes to use to power more of its fighter fleet. This issue is causing problems with reliability and keeping China’s tactical aircraft heavily reliant on imported Russian engines. China’s July 2011 order of 123 additional AL-31 jet engines supports the view that domestically-made engines still are not good enough to rely on as the mainstay to power Chinese fighters.
The latest jet engine import numbers suggest Chinese engines may now power roughly 20% of the country’s most modern fighters and strike aircraft as well as the JF-17 fighters it is exporting to Pakistan. That means at least 80% of China’s tactical aircraft fleet runs on Russian-made engines and will likely continue to rely substantially on imported Russian engines to support its tactical aircraft programs over the next two years. China’s high-performance jet engine programs are nearing takeoff but they, and China’s development of a more competitive precision manufacturing sector, appear to still have some additional runway ahead of them.
China can copy most parts of the AL-31 engines that power much of China’s J-10 and J-11 fighter fleets, but still must import turbine blades from Russia.
