Xinhua News Agency, Hainan Wenchang, July 24 (Reporter Li Guoli, Li Yun) my country used the Long March 5 Yao 3 to carry the rocket with the Long March 5 on the 24th, and successfully launched the experimental cabin to launch. This is the first time that the Long March 5 -Lane Rockets perform the "zero window" launch task.
According to the plan, I asked the Tiangu experimental cabin to be connected quickly with the sky and the core compartment. "Therefore, the Rockets must be launched at the specified time, otherwise asking the Tianyan experimental cabin will not be able to reach the designated location. It takes a huge cost to adjust the track, which will even cause the launch to terminate. You need to wait for the next launch window Liu Bing, the overall deputy chief designer of the Long March 5 LD Rockets.
In order to ensure the fire launch on time, the scientific research team optimized the launch process of the 10 minutes before the shooting, and reserved a 2.5 -minute fault treatment time before the rocket ignition. "In other words, when the launch is 2.5 minutes, the Rockets already have a ignition launch capability, which can be launched at any time." Said Lou Luliang, deputy chief designer of the Aerospace Science and Technology Group No. 5 Lane Cross Rockets.
In addition, the Long March 5 -carrying rocket also applied the take -off time deviation correction technology, with a maximum correction time of 2.5 minutes. Liu Bing said: "Popular understanding, the Rockets can be delayed at the latest 2.5 minutes, and at any time of time in this period of 0 to 2.5 minutes, the Rockets can automatically modify the flight deviation due to delayed launch during the flight. Send the experimental cabin accurately into the scheduled track. "
