The first launch of the Long March 6C was successful, wait, what is so special about this rocket, in terms of thrust, it is not as good as the Long March 5; In terms of multiple stars in one stone, it is only 4, and the highest record in the continent is; In terms of engine, it is not a liquid oxygen methane engine like the Suzaku 2. It doesn't seem like anything special, why are we talking about this?
Hey, that's the point. The Long March 6C, which is positioned in a very different way, is a new generation of rockets for future commercial launches.
Business, business, that is to take care of the market demand, is there a need for big rockets in the market? Yes, but not much, most of them are small satellites less than 100 kg, so at this time, if you develop a large rocket, will you lose money.
Therefore, the capacity of the Long March 6C is not very strong, and the carrying capacity of 700 kilometers of sun-synchronous orbit is 2 tons, which is the most demanding, and the most competitive capacity in the current commercial space market.
Although our commercial aerospace has just started, there have been several commercial rockets that have successfully flown for the first time, such as Suzaku 2, Hyperbola 1, Tianlong 2, etc., why do people choose you, you must show some real skills.
This is the advantage of the Long March 6C, there are 3 in total: the first: AAC technology, the full name is called adaptive augmentation control technology, to put it simply, it is the same as the car intelligent driving system, in the past, the weight and size of the satellite carried by the rocket will affect the dynamic characteristics and flight dynamics of the rocket during the flight, and the development team needs to adjust the parameters to meet the needs of the mission, and also do a lot of ground tests to verify whether the control strategy is accurate.
Now with AAC technology, just like the intelligent driving system of the car, it can analyze the road situation ahead, control the speed and direction by itself, and apply it to the rocket, it can automatically adjust the control parameters according to the changes of the satellite on board, so that the launch cycle is not shorter, as long as people place an order, this side can be launched quickly.
The second highlight: de-tasking. First, we will create a "standard rocket" that can adapt to the requirements of multiple missions and be put into production in rolling batches, and then, when we are ready to launch in the later stage, we will add and improve it on the basis of the standard rocket according to the needs of the launch mission. Just like Lego, the basic parts are first matched, and then special parts are created according to different models, so that it can meet the needs of high-frequency and high-density launches in the aerospace market.
The third highlight: cheap. In fact, the purpose of commercial rockets is to make the launch cheaper, how does the Long March 6C do, one is the lightweight design, the lighter the weight of the rocket, the more payload it can carry. For the first time, the Long March 6C uses a 2.9-meter foam sandwich co-bottom storage tank with a large temperature difference, which is not easy, because the Long March 6 uses liquid oxygen kerosene, liquid oxygen is minus 183 degrees, and kerosene is at room temperature.
General layout
The other is carpooling, commercial satellites are not big, some are 10-20 kilograms, in the past, a rocket cost tens of millions or even hundreds of millions, people can't afford to launch, now it has become carpooling, it has become cheaper, just like you want to go to the airport, it is very expensive to take a taxi, but it is much cheaper to take a bus.
This time, the Long March 6C launched four satellites, all of which were launched through commercial auctions, and the price per kilogram was only 80,000 yuan.
Ah, having said so much, do you think that this rocket is really amazing, if it is placed abroad, it will definitely be worth the hot search, but ah, China's aerospace feels like there are big moves every day, you just watch us have a May Day, we are Shenzhou 18 again, and Chang'e 6, our appetite has been raised, so accustomed to it, so that the Long March 6C made its first flight, and there was not even a hot search. #头条创作挑战赛###长征六号丙运载火箭首飞圆满成功#
