| Abstract: |
| 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. |
