Yesterday at 7:55 After about 2 hours Shenzhou 13 astronaut crew With the close cooperation of ground technical personnel Inside the space station core module Manual remote control Completed successfully Tianzhou-2 cargo spacecraft Rendezvous and docking test with the space station complex Video source: China Manned Spaceflight Office What is "manual teleoperation"? Manual remote control The Fifth Academy of China Aerospace Science and Technology Corporation Features specially equipped for visiting unmanned aircraft It is part of the spacecraft's GNC (guidance, navigation and control) system. Figure: Schematic diagram of the previous robot arm transfer test After the trial begins Tianzhou-2 cargo spacecraft Separated from the forward port of the core module node module Astronauts use manual remote control Controlling a cargo ship Evacuate to the designated anchorage point After a short stop Enter the translation phase Controlling a cargo ship Combined with the space station Accurately complete forward rendezvous and docking Manual teleoperated rendezvous and docking As a space station Rendezvous and docking with visiting spacecraft Important Mode It's an unmanned visiting aircraft. Backup means of automatic rendezvous and docking This trial It was the first time that an astronaut Using hand-controlled teleoperation equipment on orbit Controlling a cargo ship Rendezvous and docking with the space station Initial verification of the space station With visiting aircraft Functions and performance of manual remote control system And between heaven and earth The rationality of collaborative work procedures Fifth Academy of China Aerospace Science and Technology Corporation Zhang Qiang, deputy chief designer of the Tianzhou-2 cargo spacecraft, introduced During the entire "driving" process The astronauts' perspective is "looking at" the space station from the spacecraft Just like an astronaut "driving" in a cargo spacecraft Instrument systems facing astronauts Operating handle, etc. Both are similar to what my country has previously implemented on the Shenzhou spacecraft. The two manual rendezvous and dockings were similar This minimizes The difficulty of astronaut training Reduced burden on operation and identification What is the purpose of this docking experiment?
Video source: CCTV News Client Fifth Academy of China Aerospace Science and Technology Corporation Yang Sheng, chief designer of the Tianzhou-2 cargo system, introduced Astronauts in the core module Issue control instructions Let Tianzhou-2 separate from the core module first Then Manual control by astronauts The position and attitude of the entire cargo spacecraft Retreat to a certain distance forward Then control it again to dock Until the locking is completed Teleoperated rendezvous and docking test Very important for the construction of space stations Manned spacecraft Can be driven by astronauts Manual operation completes docking with the space station The cargo ship is different. Once the automatic rendezvous and docking function fails Cargo spacecraft Will not be able to dock with the space station Causes mission failure So the cargo ship It must have the function of remote control Mutual backup with automatic rendezvous and docking technology besides Yang Sheng also mentioned Tianzhou-2 is completing After the remote-operated rendezvous and docking test Will choose the right time to leave the space station core module Before derailment The waste will be packed and taken away Burn up in the atmosphere This is also the space station built One of the key technologies Comprehensive sources: China Manned Spaceflight Office, CCTV News Client, Guangming Daily, etc. |
