Reporters from the National Space Administration was informed that on October 27, the Long March 5 remote three carrier rocket safely arrived in Hainan Wenchang Qinglan Port. After completing a series of assembly and testing work, the rocket will choose the aircraft to carry out the launch mission at the Wenchang space launch site in China. The rocket transport fleet, consisting of the Yuanwang 21 and 22 vessels belonging to the China Satellite Maritime Survey and Control Department, set sail from Tianjin Port on October 22 and, after 5 days and nights of sailing, weathered the complex sea conditions and environmental tests, and arrived safely at the Qinglan Port Terminal in Wenchang, Hainan.
The rocket will then be transported to The China Wenchang Space Launch Site in segments by road transport, and preparations for the launch site mission will be carried out in accordance with the plan.
Long March V’s “Exclusive Seat” – yuanwang Rocket Transport Ship
The transportation mission of the Long March V rocket was completed by a formation of the rocket transport ships 21 and 22 of the distant hopes. These two rocket transport ships are the same size, 130 meters long, 19 meters wide, 5.8 meters of water depth, drainage capacity of 9080 tons, so that less than 10,000 tons of body as a marine transport vessel is not big, then why not directly use a large cargo ship to transport the Long March 5?
China Satellite Maritime Survey and Control Department of the long-range rocket transport ship formation head Shi Wei introduced, this is due to the “Long March 5” sea freight destination – Hainan Wenchang Qinglan Port’s waterway is limited, Qinglan Port into the port of the narrow, and the line twists and turns, so for the safety angle, can not use excessive ships for transport.
The two transport vessels carry40 containers carrying the Long March V rocket, with a total weight of more than 1,000 tons. The size of the case varies, with the maximum length reaching more than 30 meters, about six times the size of an international standard container. Therefore, in the process of loading and unloading, in order to ensure that the rocket is foolproof, to maintain the smoothness of the box and the accuracy of the landing point is the biggest test of lifting technology.
Because the equipment and instruments inside the Long March 5 rocket are extremely complex and sophisticated, the violent vibration may have a very serious impact on the arrow body, so not only the lifting to be stable, but also in the transport process to be more stable. So scenes like “wind and waves” are to be avoided for the Far Hope rocket carrier.
Shi said that if the transport of navigation encountered more than 2.5 meters of waves, the fleet will not be allowed to sail. Encountering bad sea conditions, the fleet will be avoided in advance, to the wind-proof anchorage to break down, in the waves below 2.5 meters, the distant hope rocket transport ship can open the shake fin, shake on its own, to reduce the impact of the wind and waves on the ship.
It is understood that the Far Hope rocket transport ship is China’s first special rocket transport ship, two Far Hope rocket transport vessels have carried out a number of Long March 5 carrier rocket containers, Long March 7 carrier rocket container maritime transport tasks. Since the two ships were delivered for use, the two vessels have sailed a total of more than 40,000 nautical miles and successfully completed more than 10 maritime transport missions.
Long March V Carrier Rocket
The Long March 5 carrier rocket, China’s largest technology span and the most powerful launch vehicle to date, made its first successful flight on November 3, 2016.
The long march 5 carrier rocket has an arrow body diameter of 5 meters, a maximum height of more than 60 meters, a weight of 865 tons, take-off thrust of more than 1100 tons. The breakthrough of the Long March 5 carrier rocket lies first and foremost in the improvement of carrying capacity. Its low-Earth orbit capacity has increased from up to 9 tons of other types of rockets in China to 25 tons, equivalent to the ability to send 16 cars into space at a time, while the carrying capacity of the higher orbit, geosynchronous transfer orbit, has increased from 5.5 tons to 14 tons.
As a new self-developed carrier rocket, Long March V, the whole arrow adopts more than 200 core key new technologies, the proportion of new technology is almost 100%. International development of new rockets, including satellite spacecraft, the proportion of the use of new technology is generally not more than 30%.
Long March 5 is on its shoulders. A series of major space launch missions by China, including the manned space station, the Chang’e-5 lunar probe and the Mars rover, will be undertaken by the Long March 5 carrier rocket.
Long March 5, come on!
