| 降落伞应用日益广泛.为了有效地降低降落伞空投的物资消耗和危险性，开展飞机空投降落伞一体化仿真系统设计具有重要意义.研究了系统的关键技术，运用数字地球技术、三维LOD技术和可视化技术等，实现了大范围三维地表数据的海量存贮与快速表达，实现了投放环境、飞机（队列）飞行、空投降落伞时起航、抛投、降落等多环节一体化模拟仿真.并以VS2010为开发平台，利用ChinaStar GIS组件，设计与开发了基于三维大地形模型的飞机空投降落伞一体化仿真系统.通过对系统的试用和检验表明,系统对降落伞投放环境、飞机（队列）飞行及空投降落伞降落过程的一体化模拟仿真取得了较好的效果，模拟结果具有较高的可靠性，能为实际空投提供可靠的参考信息. |

| Parachutes are increasingly used in variant areas. An integrated simulation system of parachutes dropping progress to reduce risks and material waste. Key technologies related the system were studied, and was designed digital earth technologies, 3D LOD and visualization technology were applied, Mass storage and rapid expression of 3-D spatial data about the surface of the earth were realized. Models were built for an aircraft, parachute and the flight of an aircraft or aircraft queue. The simulation were designed and coded for taking off of an aircraft or aircraft queue, airdropping, and landing of a parachute or a parachute queue. A integrated simulation system of parachutes dropping progress based on the digital earth technologies by use of VS2010 and ChinaStar GIS component. The simulations of parachutes dropping progress were proved to be highly reliable by field tests and validation. The system could provide useful information for airdropping of parachutes. |
