At 15:37 on October 31, the Long March 5B Yaosi 4 carrier rocket aboard the Mengtian experimental module was launched from the Wenchang Space Launch Site in China. At 21:41 on December 15, 2023, the Long March 5 carrier rocket ignited and took off at the Wenchang Space Launch Site in China, and then successfully sent the Remote Sensing 41 satellite into the predetermined orbit. The launch mission was a complete success.

The successful development of the Long March 5 marks the upgrading of China's launch vehicles and is a key step in moving from a major space country to a powerful space country. It has made the low-orbit and high-orbit carrying capabilities of China's launch vehicles leap to the world. second.

Long March 5 booster

The Long March 5 3.35-meter diameter module inherits the existing 3.35-meter diameter technology of the original Long March rocket core stage and uses liquid oxygen and kerosene propellants. Install two 120-ton YF-100 liquid oxygen kerosene engines, plus the pressurized transportation system and servo mechanism matching the engines.

The booster structure is similar to the rocket body structure of the Long March 3B launch vehicle, and the booster tank adopts an equilateral triangle grid reinforced shell structure. The booster liquid oxygen tank uses full friction stir welding technology.

The nose cone of the booster is an oblique cone, consisting of a hemispherical end and a truncated cone shell. The tilt angle of the nose cone of the 3.35-meter-diameter booster is 15°. The tip is subject to aerodynamic heating during flight. The truncated cone shell adopts a truss-type semi-monocoque thin-walled structure, and the outer surface skin is made of high-temperature resistant fiberglass material.
