摘要：对为象从精力节省的观点的地区性的航班一样的运输飞机的推进器有成长兴趣。为在飞机上利用一个推进器推进系统的重要考虑是在推进器冲流和另外的空气动力学的表面之间的空气动力学的相互作用。使用因此是必要的一简化但是为推进器建模的相对精确的工具，与广泛地使用的致动器磁盘模型一起。这个模型的优点是它以要求的计算时间易用、便宜。另外，它也生产可接受的结果。在这研究，一个新区域化的致动器磁盘模型在一架真实四推进器的飞机上在推进器冲流干扰效果的分析被利用。结果与不活跃的致动器磁盘的盒子相比，它证明推进器冲流在电梯引起增加并且拖系数。旋转冲流引起的明显的偏航效果被注意，它应该在设计阶段被考虑。区域化的致动器磁盘模型为推进器作为一个快、相对精确的模型被评估初步的设计。

摘要：Motion simulator usually appears the phenomenon of false cues and the workspace is limited in the process of washout. The proposed washout algorithm combines fuzzy logic control with the vestibular system to design the tilt coordination fuzzy adaptive filter, in order to minimize the vestibular sensory error below the human perception threshold. Owing to tilt coordination angular velocity limiter, the loss of low-pass acceleration must be compensated by the acceleration transform model. The translational channel decreases the possibility of the workspace beyond limitation and expands the scope of motion platform simulating input acceleration by using third-order filter. The simulation results show that the proposed algorithm can effectively overcome the phase retardation of classical washout algorithm, and then prevent the produce of false cues, decrease the displacement of motion platform simultaneously; in addition, white Gaussian noise simulates large variations in acceleration. The proposed washout algorithm can have maximal extreme value of acceleration and accurate simulating performance in general. It also proves that the proposed washout algorithm has a strong adaptability and reliability, which can effectively improve the dynamic fidelity for motion simulator.
