旅游者号超轻型飞机的数学模型与计算机绘图

超轻型飞机AD100是我院自行设计的我国第一架鸭式布局旅游机。它由机身、主翼、中翼、前翼、翼尖小翼、起落架以及发动机等部件组成。飞机各个部件的轴测图或各部件组合轴测图以及全机外形图,可在IBM4341计算机上利用双三次B一样条曲面和改进的双主次Coons曲面算法,在TEK618上显示和在TEK4662绘图仪上绘制。本程序可在绘制中随意改变三维空间角度,並能绘制出飞机某部件及其切面图,以便于加工样板和绘制模线。

Mathematical Model of the TRAVELLER Ultralight-Aircraft and Computer Drafting

The TRAVELLER(model AD-100)is a canard configuration ultralight aircraft designed and produced first in our country by Nanjing Aeronautical Institute.It consists of fuselage,canard,two main wings,wingtip-fin,landing gear and engine,etc.With applying the algorithm of the bicubic B-spline surface and the advanced cubic Coons curve,the axonometric picture of the aircraft's parts and its assembly can be displaied on TEK 618 and drawn on TEK 4662 plotter both which are operated with the computer IBM 4341,the aircraft contour can be drawn as well.Three-dimensional azimuth angle of this axonometric picture can be dischanged arbitrarily within the period of drawing during the use of the present program,and can be drawn out the aircraft's part and its sectional view to process the template and draw the mould line.
