"Long March No. two" (CZ-2C) is a two stage liquid launch vehicle, which is developed by the China launch vehicle technology research institute. The rocket is 43 meters long and 3.35 meters in diameter at the one or two sub level. The take-off weight is about 242.5 tons. It is mainly used to launch the low orbit and solar synchronous orbit satellites.
The Long March two rocket was first launched in September 1982. Based on it, China has developed the Long March two /SMA and the Long March two /SM rocket. The long march No. two rocket is mainly undertaken by China's return type science and technology test satellite, detection No. 1, detection No. two, marine No.1 satellite, environment one satellite and American Iridium series communication satellite.
"Long March three" (CZ-3A) is a three stage cryogenic liquid launch vehicle developed by the China Academy of Launch Vehicle Technology (hereinafter referred to as the "rocket academy"). The rocket is 52.5 meters long, one or two sub - class diameter 3.35 meters, three sub - class diameter 3 meters, take off weight about 243 tons, mainly used for launching geosynchronous orbit satellites, carrying capacity of 2.6 tons.
The long march three a rocket mainly took on the mission of the Fengyun meteorological satellite, the Beidou navigation satellite and the lunar probe of "Chang'e 1". Since the first successful launch in February 8, 1994, the success rate of the launch has been 100%.
"Long March No. three" (CZ-3B) is a high track and large thrust launch vehicle, which is developed by the Chinese Academy of Launch Vehicle Technology Research Institute ("rocket academy"). It is based on the long march No. three a rocket and bundled four boosters on its one sub level. It is mainly used to launch the earth synchronous transfer orbit satellite. To launch an arrows or other orbiting satellites.
The rocket is 56.5 meters long, the core one or two is 3.35 meters in diameter, the core three is 3 meters in diameter, the single push diameter is 2.25 meters, the take-off weight is about 456 tons, and the geosynchronous transfer track carrying capacity is 5.5 tons.
The long march No. three rocket is the main rocket for commercial satellite launch service in China. It mainly bears the mission of launching the launch mission of the Committee star 1, Ba star 1R, Nei star 1R, W3C, Asia Pacific seven, Zhongxing eleven, zhongstar twelve, Bolivia star international and the Chang'e three lunar probe.
The "Long March No. three C" (CZ-3C) was developed by the Chinese Academy of Launch Rocket Technology ("rocket academy"). It was formed by reducing two boosters on the basis of the long march No. three, and mainly used to launch a geostationary transfer orbit satellite.
The rocket is 56.5 meters long, the core one or two is 3.35 meters in diameter, the core three is 3 meters in diameter, the single push diameter is 2.25 meters, the take-off weight is about 345 tons, and the geosynchronous transfer track carrying capacity is 3.9 tons.
The long march No. three rocket was successful in the first flight in April 25, 2008. In recent years, it has mainly undertaken the mission of "Tian chain 1", the Beidou navigation satellite and the lunar probe of Chang'e two.
"Long March eleven" (CZ-11) is a new generation of solid launch vehicles developed by the China Launch Vehicle Technology Research Institute ("rocket academy"). It is mainly used for rapid mobile launch of emergency satellite.
The rocket is 20.8 meters long and weighs 58 tons. The take-off thrust is 120 tons, the 700 km solar synchronous orbit carrying capacity is 350 kilograms, and the low rail carrying capacity can reach 700 kilograms. It is mainly used to meet the needs of microsatellite launches in emergency situations such as natural disasters and emergencies. After receiving the mission command, the rocket completes the technical preparation and launching of the rocket within 24 hours, of which the launch time of the launch point is not more than 1 hours, and has the "day launch" capability.
In September 25, 2015, China's long march series carrier rocket family first solid launch vehicle and the only type of solid rocket in our new generation launch vehicle, the long march eleven rocket, ignited in Jiuquan satellite launch center, and succeeded in sending 4 tiny satellites into space.
The upper level of the expedition I was developed by the Chinese Academy of launch vehicles (Rocket Technology Research Institute). It is an independent first class aircraft added to the rocket and can launch more than one spacecraft at a time. After the rocket has been transported to a certain orbit, it can fly autonomously for several times, and launch one or more spacecraft directly into different orbit space. Because it is like ferry cars to the passengers in the car to different locations, it is known as "space ferry".
Expedition 1 is main diameter of 2.8 meters, using 1 6.5 thousand cattle pump pressure conventional propellant engine, has two start-up capacity, and the working time is about 6.5 hours.
In March 30, 2015, the expedition 1, powered by the long march three rocket, was successfully launched for the first time.
