CGTN独家专访天舟货运飞船总设计师白明生

天舟六号货运飞船是我国空间站应用与发展阶段的首发航天器，是改进型货运飞船的首发船，同时也是天舟六号到天舟十一号组批生产的首发货运飞船，承担着空间站物资保障、在轨支持和空间科学试验的任务。在天舟六号发射之际，CGTN独家专访了中国航天科技集团五院天舟货运飞船系统总设计师白明生。

The Tianzhou-6 cargo ship is the first spacecraft launched during the application and development stage of the China Space Station. It's also the first cargo spacecraft in the Tianzhou-6 to -11 batch, and it will provide significant material support for taikonauts. On the occasion of the Tianzhou-6's launch, CGTN sat down with Bai Mingsheng, the chief designer of the spacecraft from the China Academy of Space Technology, for an exclusive interview.

viewed as number one in the world

据白明生总设计师介绍，作为改进型货运飞船的首发船，天舟六号密封舱的空间加大，增加了装载能力，其平台配置得到优化。数据显示，天舟六号密封舱货物装载空间提升了 24%；装载能力由 5.5 吨增加至 6.7 吨，提升了 22%；整船物资装载能力由 6.9 吨提高至 7.4 吨，使货运飞船发射频次从2年4发降低至2年3发。

According to Bai, as the first spacecraft in the improved series, Tianzhou-6 has more space and better carrying capacity. Featuring an optimized configuration platform, data shows the space for cargo in Tianzhou-6's airtight cabin has increased by 24%. Carrying capacity has also improved from 5.5 metric tons to 6.7, an increase of 22%. The cargo loading capacity of the ship has also increased from 6.9 metric tons to 7.4, while launch frequency has been reduced from four over a two-year period to three in two years.

空间应用在货物比例中大幅增加

Space applications increased significantly in the proportion of cargo

白总师说，天舟六号的货物依然划分为三大类：物资保障、在轨支持和空间科学试验，但具体比重有明显变化。由于空间站应用发展阶段主要侧重于应用，实验装置、样品和设施大幅增加。此外，本次上行货物主要是给神舟十六号乘组，是三个人、九个月的物资，其中一个月，将作为应急备份使用。”

Bai said the cargo of Tianzhou-6 is still divided into three categories: life materials, maintenance, and space science experiments. However, he said the specific proportions have changed significantly. As the space station application and development stage mainly focuses on application, experimental equipment, samples, and facilities have been dramatically increased. In addition, the cargo is mainly for the Shenzhou-16 crew, in other words, three people who require nine months of supplies. One month of supplies will also be used as backup for emergencies.

天舟货运飞船家族的发展

The evolution of the Tianzhou family

据白明生总设计师介绍，天舟一号和二号为一个批次。天舟三号、四号和五号属于一批。天舟六号到十一号为一批次。今后设计规划为六艘船为一批。天舟十二号的状态已经开始梳理。后续规划有全密闭、半开放和全开放的货运飞船，还将不断有改进型号出现。

According to Bai, Tianzhou 1 and 2 belonged to the first batch. Tianzhou 3, 4 and 5 belonged to the second batch. Tianzhou 6 to 11 are in the third batch, and future designs are planned as a batch of six ships. Planning is already in place for Tianzhou 12, with further modifications and improvements expected.
