According to the official sources of China Aerospace Science and Technology Corporation, on October 9, the first courtyard of the company
The first Institute of China Aerospace Science and Technology Group launched the preliminary research on the new generation of manned launch vehicle in 2017. After many rounds of demonstration and development, it has finally taken a key step.
According to designChina's new generation of manned rockets have a height of about 87 meters, take-off weight of about 2200 tons, take-off thrust of nearly 2700 tons, LTO (lunar orbit) carrying capacity of no less than 25 tons, and the current maximum is only about 8 tons.
In other words, the new rocket can send the new manned spacecraft directly into lunar orbit with an apogee of more than 380,000 kilometers.
According to reports, the new rocket willSeveral parallel engines, 1000-ton bundling load transfer, integrated design of rocket body structure, and a large number of new materials and technologies are adopted.It greatly improves the efficiency of transportation.
Simultaneous adoptionA series of new technologiesFor example, new escape system, lightweight and efficient structure design and advanced manufacturing, lightweight and high reliable thrust vector control, rocket longitudinal coupling vibration suppression, advanced test launching, redundancy of rocket power system and flight control reconfiguration, cold helium pressurization, low impact and high reliability ship-rocket separation, etc.
Among them,The design and manufacture technology of large diameter and large temperature difference cryogenic common bottom tank, the design and manufacture of bottom force transmission structure of 100 ton thrust tank, and the electrostatic thrust vector control of large thrust rocket engine are also the first in the world.
In addition, the rocket will fully inherit the mature engine technology such as Long March 5 and Long March 7, high reliable flight control technology, and simplify the escape mode to improve the safety of astronauts.
As early as 2017, China's Aerospace officials have disclosed that China is steadily advancing the pre-study of manned lunar landing. At the Zhuhai Air Show in November 2018, China Aerospace Science and Technology Group demonstrated the 1:10 scale model of the new generation of manned rockets for the first time.
Scaled Return Module of New Generation Manned SpacecraftIn addition, there will be service cabin, high reliability, high safety, low cost, but also very comfortable.
At that time, synchronized appearance, the most upright middle C position is the height of 100 meters, near-ground transport capacity of 100 tons, can send a hundred cars to the sky.Heavy rocket Long March 9。
Long March No. 5 and Long March No. 5 BThe latter is the main force in the construction of China's space station, which will be used to launch the core module and the test module.
Long March No. 6, No. 7, No. 8 and No. 11Among them, Long March 6A on the right side is the first long march rocket with solid booster in China.
China Space Station Core ModuleIt is more than 16 meters long and consists of node cabin, small column section, large column section, back passage, resource cabin, etc.
10 meters long.Space Station Manipulator。
