项目摘要

This year is a final phase of this project. Research results of this year are to make clear the method of displaying flight conditions of a Space Plane and to summarize this project.Since the Space Plane can fly automatically without human control, it is important that the flight display of the Space Plane can be used as a devise that warns flight conditions to a pilot. This research has investigated the use of the three dimensional display based on the computer graphics system to evaluate the effectiveness of the three dimensional display.Two kinds of three dimensional display are investigated. One is a display of a three dimensional airplane to show the pilot the airplane attitude. The other is the superimposed topographical map over the flight display to illustrate the flight path that was input in the flight computer. These new display methods are very effective to show a pilot flight conditions quickly and qualitatively. However, since quantitative information is not sufficient in the three dimensional display, it is necessary to use the traditional display at the same time.In the first phase of this research, the dynamic equation of the Space Plane and the modeling method for aerodynamic forces are investigated to obtain the flight dynamic model of the Space Plane. Using this model, the dynamic characteristics in the hypersonic flight are revealed. In the next phase, a flight path of the Space Plane is calculated by the use of the optimal control theory. The optimal rising path, cruising path and return path are investigated. In the final phase, a flight simulator with the three dimensional computer graphics system is made to establish the design method for the Space Plane flight display.

今年是该项目的最后阶段。本年度的研究成果是为了明确空天飞机的飞行状态显示方法，并对该项目进行总结。由于空天飞机可以在没有人类控制的情况下自动飞行，因此空天飞机的飞行显示器可以用作向飞行员警告飞行状态的装置是很重要的。本研究探讨以电脑绘图系统为基础的三维显示器，以评估三维显示器的效能。一种是三维飞机显示器，向飞行员显示飞机姿态。另一个是在飞行显示器上叠加的地形图，以说明飞行计算机中输入的飞行路径。这些新的显示方法是非常有效的，显示飞行员的飞行条件快速和定性。本文首先研究了空天飞机的动力学方程和气动力建模方法，建立了空天飞机的飞行动力学模型，并对空天飞机的飞行动力学模型进行了仿真研究。利用该模型，揭示了高超声速飞行时的动力学特性。在下一个阶段，空间飞机的飞行轨迹的最优控制理论的使用计算。研究了最优上升路径、巡航路径和返回路径。最后，利用三维计算机图形系统制作了一个飞行模拟器，建立了空天飞机飞行显示器的设计方法。
