飞行模拟器视景仿真毕设论文

摘要
随着飞行训练的成本越来越高，培训机构急需能够部分替代实际飞行训练的飞行模拟器进行飞行模拟训练，以有效地减少飞行训练的成本，提高飞行训练的效果。

飞行视景仿真是飞行模拟器的一个重要组成部分，建立飞行视景仿真系统，不仅可以降低其研制和开发的费用和周期，减少各种飞机机体实际内部故障或者不可预见的复杂飞行环境导致的可能性故障，还可以向飞行人员模拟出真实的三维场景及有效的飞行信息，提供逼真的飞行效果与飞行姿态，使得培训人员可以更快速更安全更熟练地进行各种飞行操作设备，顺利完成各种飞行任务操作以达到培训目的。

本文在分析飞行仿真的需求基础上，设计的飞行模拟器可以较好地完成飞行仿真功能，提供多种飞行训练场景，有助于飞行技术的提高和飞行体验。

在飞行仿真的理论基础上，借助相关的可视化技术，综合运用模型构造、系统运行、模型驱动等一系列技术，利用Creator软件进行仿真建模，完成飞机、飞行场景的建模，设计基于Vega Prime环境的飞行视景仿真系统，实现动态在线飞机飞行运动的全过程，为飞行训练提供良好的飞行仿真环境。

本系统可以建立虚拟飞行训练环境，能有效的完成基本的飞行条件，提供多种飞行场景方案，但同时也有控制功能较少，场景较为单一的缺点，待后续技术条件成熟时进一步的完善与提高。

Abstract
With the increasingly high cost of flight training in urgent need of training institutions to a partial substitute for the actual flight training, flight simulator flight simulator training to effectively reduce the cost of flight training, flight training effect. Flight simulation is an important part of the flight simulator, flight visual simulation system, to establish not only to reduce its research and development costs and cycle, to reduce a variety of airframe internal fault, or lead to unforeseen complex flight environment the possibility of failure, but also to the flight crew to simulate the real 3D scene and flight information, provide a realistic flying effect and flight attitude, making training faster, safer and more proficient in a variety of flight operations equipment, the successful completion a variety of mission operations in order to achieve the training objectives.
In this paper, the demand on the basis of the analysis of flight simulation, the design of the flight simulator can be better to complete the flight simulation capabilities, providing a variety of flight training scenarios, contribute to the improvement of flight technology and flight experience. Based on the theory of flight simulation with visualization technology, and integrated use of a series of model construction, system operation, and model-driven technology, Creator software for modeling and simulation, complete aircraft, the flight scene modeling, design-based flight of the Vega Prime environment visual simulation system, the dynamic online airplane flight movement for flight training, flight simulation environment. This system can create a virtual flight training environment, the completion of the basic flight conditions, and offers a variety of flying scenes program, but we also have less control functions the shortcomings of single scene until the follow-up technical conditions are ripe to further improve and enhance .
