"The centrifuge alarm hasn't been triggered for 13 years." "The centrifuge alarm hasn't been triggered for 13 years." Yang Liwei, the space hero and deputy director of China's Manned Space Engineering Office, revealed in a report at Wuhan Institute of Biological Engineering that astronauts' training is very arduous. However, during the centrifuge rotation training, "the alarm which could be pressed to stop when unable to endure has not been triggered for 13 years."
At 9:20 AM yesterday, under the anticipation of more than 18,000 students on campus, space hero Yang Liwei arrived as scheduled and participated in the groundbreaking ceremony of Qian Xuesen Square. In the afternoon, during his presentation to over 1,800 teachers and students, Yang Liwei said with emotion that the biggest challenge for astronauts during their missions is adapting to the overload acceleration when the manned spacecraft launches and returns. For this reason, astronauts undergo brutal ground-based centrifuge training for acceleration loads.
"Large roller coasters can make people terrified, but their acceleration is only slightly over 2G, while Chinese astronauts experience up to 8.5G during centrifuge training on the ground," Yang Liwei said. This means adding eight times one's own body weight. During each training session, everyone would train to the point of facial distortion, tears flowing involuntarily. To prevent astronauts from being unable to bear it, an alarm is installed on each person's training equipment. If they cannot endure, they can press the alarm, and the centrifuge will immediately stop. "To date, in 13 years of training, no astronaut's alarm has been triggered, and no astronaut has requested to drop out midway," Yang Liwei's words were followed by thunderous applause throughout the venue.
It is understood that due to the previous care given to Wuhan Institute of Biological Engineering by the late scientist Qian Xuesen, Yang Liwei's invitation to inspect the school was also thanks to the strong support of Professor Qian Yonggang, Qian Xuesen's eldest son, and General Tu Yuanji, the former head of Qian Xuesen's office.
