China's engine has left the United States behind, and the US military can't understand the YJ-17 engine
Many people think that the YJ-17 is the ship-based version of the DF-17, but the engine of the YJ-17 is full of secrets. Look at this engine that looks like a gas stove. Even the US military can't understand it.
General hypersonic glide missiles use rocket boosters as their power system. The missile first uses a first-stage booster to enter the thin atmosphere, then uses a second-stage booster to continue ascending to about 100 kilometers in height, then quickly descends and enters the atmosphere at about 30 kilometers in height. The glider itself does not have and does not need a traditional engine. It relies on a special "waverider" aerodynamic shape to generate lift from the shock waves at high speeds, like a stone skipping on water, gliding and maneuvering at the edge of the atmosphere to achieve an unpredictable "Qian Xuesen trajectory."
However, the body of the YJ-17 is very smooth, looking more like a hypersonic aircraft than a missile. What kind of engine China has used is a core secret.
Nevertheless, this also made the US realize that China has truly surpassed the United States in the field of engines. Whether it is conventional turbofan engines, or next-generation detonation engines, scramjet engines, or other forms of combined propulsion engines, China has not only overcome the technical challenges, but they are also being tested and flown in batches.
This impact brought by the 93 will take a long time for the US to digest, because there are so many new concepts that even the US hasn't proposed before.
