Description

Technical field

[0001] The invention belongs to the technical field of flight simulation, and in particular relates to a visual simulation method of a nearby space vehicle based on a distributed architecture. Background technique

[0002] The flying speed of nearby spacecraft is usually greater than 5 times the speed of sound, and the flying coverage is wide, and the flying environment is complicated. Any small disturbance can have a greater impact on its control performance. The simulation data and curves provided by traditional digital simulation are not enough to comprehensively and intuitively reflect the flight status characteristics and control performance of nearby spacecraft. Therefore, the use of distributed real-time simulation architecture to fully verify the control performance and real-time performance of the aircraft, and the use of visual simulation technology to vividly display the real-time simulation control effect, has a very important role and significance in ...
