基于平面投影的综合飞行引导算法研究

Comprehensive Flight Guidance Algorithm Research Based on Planar Projection

针对大圆航线在地球表面实现圆弧航段内引导飞行、两相邻航段间内切转弯飞行时的弧面几何计算误差大、过程复杂的问题,本文采用一种基于平面投影的引导算法,在进行高斯-克吕格投影后的平面内进行引导解算,以实现圆弧航段引导飞行。本文在VS2010环境下实现了多航段内引导和航段间四种转弯方式引导飞行,搭建的仿真验证平台可通过预设航线,对基于平面投影的引导算法进行验证,仿真环境还具备常速飞行和按时到达等引导飞行能力。

Focus on the problem that the great circle route algorithm calculates complicatedly with great deviation when it is applied to navigation on circular flight segment and tangent swerve between two neighboring flight segments,this paper proposed a guidance algorithm based on planar projection,which is calculated with the plane after Universal Transverse Gauss-Kruger Projection.Finally,the experimental results with VS2010show that this algorithm is an effective method of navigation on circular flight segment and tangent swerve between two neighboring flight segments,besides,constant-velocity and arrival on time can be achieved on this simulation platform.
