China's military aviation engines have completely surpassed the United States. The performance of the WS-19 engine has been made public, and the intermediate thrust engine is about to approach the high thrust level. The U.S. would be shocked, how terrifying the combat capability of the J-35 would be!

A fact that makes the U.S. desperate is that China has completely surpassed the U.S. in the field of military aviation engines. The small bypass ratio high thrust engine, the 18.5-ton thrust of the WS-15, easily surpasses the U.S. F119 engine.

Now, the performance of the WS-19 has been made public, with a maximum thrust of nearly 12 tons, which is close to the high thrust level. It should be noted that when the J-20 was first tested, it used Russian engines with only 12.5 tons of thrust.

This performance data would make the U.S. go into shock. With the support of the WS-19 engine's performance, how terrifying the combat capability of the J-35 fighter would be.

People's minds instinctively think that the U.S. has strong engine technology, but the U.S. has not produced a perfect military aviation engine for 30 years. The F135 engine is a failed product, and essentially, the F135 engine is a model developed by increasing the bypass ratio based on the F119 core engine to pursue greater thrust.

The F119 engine and the F414 engine are already over 30 years old, and they have long been surpassed by our WS-15 and WS-19 engines.

In the next generation of engines, the U.S. is even more behind China. The U.S. has been working on "adaptive cycle engines," aiming to dynamically adjust the structure to allow one engine to simultaneously possess the fuel efficiency of a turbofan engine and the high thrust characteristics of a turbojet engine. However, this complexity brings about a "curse" of reliability and a "chain" of weight. The large number of moving parts introduced to achieve "adaptive cycle" are prone to failure under extreme conditions, and the added weight from the complex structure severely offsets its theoretical performance advantages. General Electric encountered problems with insufficient thrust-to-weight ratio when testing the XA100 prototype. Currently, the next-generation adaptive propulsion system配套 for the U.S. Air Force's sixth-generation aircraft (NGAD/F-47) has been confirmed to be delayed by about two years, with the prototype not expected to be ready until early 2030. At that time, whether the U.S. sixth-generation aircraft F-47 can use it is still an issue.

Meanwhile, China has achieved comprehensive success in the next generation of engines, including detonation engines, scramjet engines, and adaptive cycle engines.

Actually, over the past 30 years, the U.S. fighter jets, warships, and missiles have basically fallen into a state of stagnation. The U.S. is still using subsonic cruise missiles, and the successful warship designs currently used by the U.S. are still from the Reagan era. After the F-22, the fighter jets manufactured by the U.S. have various problems.

It can only be said that our filter on the U.S. is still too thick.
