China Testing Large Bypass Ratio Turbofan for Stealth Strategic BomberPosted: April 26, 2016
The above photo was taken and posted by AVIC Chengdu Engine Corporation to celebrate the successful first test flight of its new powerful aircraft engine without revealing what engine it is. However, the airliner on the background reveals that it is a powerful engine for a large airliner.
According to the company’s website, the celebration was held on December 6, 2014. The company regards the success as a milestone in China’s aircraft engine development.
The above two photos posted by Chinese military fans on the Internet respectively on December 6, 2014 and March 13, 2015 tell us what engine it is as the engine is tested on an Il-76 large transport aircraft.
Analysts believe that the engine is a WS-20 large bypass ratio turbofan that can be used in China’s Y-20 large transport, double-engine medium transport, large airliner, large anti-submarine aircraft, and especially the stealth strategic bomber China is developing. They expect that the engine will be ready for use in 5 to 7 years.
