Tiangong-1 is China’s first space station, which serves as an experimental testbed for orbital rendezvous and docking. Tiangong-1 is also the prototype of China’s future space lab. In this work, we perform the simulation of the turbulent state of the two-cabin simplified model (10-meter long, with a diameter around 3.5 meters in the cross section) of the Tiangong-1 spaceship in the failing process (flying height=65KM, Ma=13). By using 16,384 processors of the Sunway system, the computation job, which normally takes 12 months, was finished in 20 days. In addition, the simulation results provide a good fit to the result of the wind tunnel test.
