Rockets with the first place in service years

On November 26, 1975, the Long March II Rockets developed by the China Laureate Rocket Technology Research Institute accurately sent the first returning satellite into the scheduled orbit to open the curtain of my country's conventional liquid propulsion rocket.

In order to achieve the launch of more satellites, the model team organized the improvement design of the Long March 2 rocket. The modified rocket's near -ground orbital carrier capacity has been increased from 1800 kg to 2500 kg, and the reliability has been greatly improved. Therefore, there is another "number number" -Long March 2 Cross. After the first flight of the long Rockets was successful, it fully replaced the Long March 2 Rockets to perform launch tasks and achieve seamless upgrades.

In addition, since the first flight in 1982, the Long Erbing Rockets had successfully successfully successfully launched as of the end of 1998. Therefore, it was awarded the "High -quality Long March 2 Crown Rockets Gold Medal", which is my country's first "gold medal rocket".

Rockets with the first place in use

Based on the long two-B Rockets in my country, it has developed the long march No. 2/FP, Long Erbi/SMA, and the upper-level long two-B-1S-1S-1S-1S-1S-1S-1S-1S-1S-1S-1S-1S Construction rocket. Long Erbi and its improved rockets are the only launching rockets in the Long March series of launch vehicle with near -ground orbital (LEO), Sun synchronous orbit (SSO), Earth synchronous transfer orbit (GTO) and large elliptical track satellite capabilities. Methods include single -star launch, skewers and two stars, parallel Samsung launch, and multi -star launch on the side. Therefore, the long two -B and its improved rocket are the most flexible and most widely used carrier rockets in my country.

Rockets of the first place in the "Derivative" model

The two -level state long Rockets are the cornerstone of my country's conventional liquid propeller rocket. Under the guidance of the "down tied up", it has quickly built the scores of rocket rocket rockets in our country, setting up a platform for my country's aerospace industry.

Coupled with the three -child -level liquid hydrogen oxygen, it is derived from the Long March No. 3 rocket to launch the Earth's synchronous orbital satellite, and then derives the Long March III A, the Long March 3, and the Long March 3 -C series Rockets.

Long March No. 3 Rocket Rocket

Coupled with the conventional three -son -level, the Long March 4 rocket is derived to launch the solar synchronous orbital satellite.

Long March No. 4 Cross

Binding four similar types of liquids to boost rockets, that is, derived the Long March 2 E large thrust carrier rocket; further improvement and optimization, the "hero, the top beam pillar" built by my country's space station -Long March 2 F Rockets.

Rockets involved in international launch services

my country's external launch services and technical cooperation began in 1985. In 1985, China participated in the Paris International Aviation Exhibition for the first time, and signed a contract with French company with a long -term Rockets, which was equipped with a French company's microconentity test device while launching a returning satellite. This was later regarded as a sign that China Aerospace entered the international business launch market for the time.

In November 1987, China signed a contract with a Swedish company, which clearly used the long Erbing Rockets to carry the "Freja" scientific test satellite that launched the Swedish company. On the day, the fourteenth return satellite launch task was successfully completed. It can be said that Chang Erbing Rockets is the first type of rocket involved in international launch services in my country.

Rockets to realize the first international cooperation in my country to explore the first international cooperation in China

On December 30, 2003, the Detect 1 Satellite No. 1, which was successfully launched at the Xichang Satellite Launch Center at the Xichang Satellite Launch Center, was the first satellite (equator) in the "Double Star" plan. The Earth Space Double Star detection plan is a cooperation project of the National Space Administration and the European Space Administration. The successful rise of the long two -C/SM rocket realizes the first international cooperation of my country's space exploration. When the Chinese Academy of Sciences proposes to cooperate with the European Air Bureau to develop the Earth Exposure Double Star Project, what kind of carrier rockets choose are the key issues of the project. Long Erbing Rockets was selected for its glorious launch history. According to the requirements of the satellite work track and posture, the long Erbing Rockets use the new design of the above level. The new long two -B -Rockets live up to expectations and successfully launched for the first time.

The first time the domestic satellite was launched to a large ellipse orbit rocket

The long two -C/SM rocket successfully launched a satellite No. 1 to a scheduled satellite work track with a scheduled satellite at a nearly 550 -kilometer and 66970 km distant locations. This was the highest working track launched in my country at that time. It requires a rocket to have considerable thrust in such a high orbit. Not only should the satellites be sent to the orbit, but the satellite attitude must be adjusted to a certain position.

The long two -C/SM rocket adopts the long two -C and plus solid superior upper stage, and the first and second levels send the satellite to the mooring orbit; after the upper level and the second level are separated, the posture is adjusted, slipped, and rotated. The orbit changes to the orbit to enter the track; the upper stage will disappear and adjust the posture, so that the spin shaft of the satellite is perpendicular to the zodiac plane, and the upper level will be rotated to the satellite to request the number of rotations, and then separate from the satellite.

For the first time with the above -mentioned joint execution of launch tasks

The most prominent feature of the long two -C/SM rocket is the development of a brand -new upper class. The above level adopts a spin -stable gesture control method, and for the characteristics of spin and stability, it has completed the development of important technologies such as the large -angle rate and long life habit group, the four -diversity GPS receiver, and the large thrust and small deviation solid engine.

The tower equipment of the different launch fields and the interface relationship with the carrier and the climate environment are different, and the rocket is very highly adaptable. High reliability and high adaptability are synonymous with the long two -Crown Rockets.

From April 30th to July 16th, 2022, the Chang Erbing Rockets successfully completed the 4 -time launch mission in Jiuquan, Xichang, and Taiyuan. Two of them were originally planned to launch one day.

The first type to realize the one -class controlled rocket

On July 26, 2019, the Long Erbing Rockets carried out the first -level re -incident control technology in my country in the Satellite Satellite Launch Mission in the 30th Group of Remote Sensing. The team has successively broke through the grid rudder of the complex packets of the wide Machu, and then entered the child -level pneumatic design and accurate indication technology, the sub -re -entered control technology under the condition of high dynamic strength and dynamic dynamic coupling, High-integration intelligent electrical design technology and other realization of system design-one successful flight, the actual point distance theoretical fall point is only 1.9 kilometers. After the equipment, the range of the one -child level will be reduced by more than 96%.
