飞艇升空过程超压控制可视化仿真

Virtual simulation of the pressure control of a airship during its rising in the sky

基于Vega与Creator平台研究了飞艇升空过程中飞艇超压控制的三维可视化仿真技术,建立了飞艇升空过程的数学模型与适合研究飞艇升空过程中超压控制的大气模型,并在Creator平台上开发了飞艇的实体模型.基于所建立的数学模型和实体模型,在VC6.0环境下完成了飞艇升空过程超压控制可视化仿真系统,给出了可视化的仿真结果.通过仿真试验分析,结果表明数学模型可行,在设置的超压控制策略下飞艇对环境有一定的自适应能力,能够比较平稳地升到所设定的高度.

The technology of the three-dimension virtual simulation in the super pressure control of the airship＇s flight was studied based on Vega/Creator. The mathematical model for the rising airship in the sky is presented. The atmosphere model of the pressurized blimp is also set up on the platform of Creator. With all these, the virtual simulation system is established under VC6.0 and the virtual simulation result is given. By means of simulation experiment＇s analysis, the illustrative results show that the model is feasible. Under the strategy of the given super pressure control the airship is adaptive to the environment and can reach the given altitude steadily.
