低成本小型高机动飞机航向下滑天线伏尔功能的实现

Realization of VOR Function of Low Cost, Small and High Maneuverable Aircraft Heading Down Antenna

针对低成本小型高机动飞机的机体小、复材密度大、速度快、机动强度大、成本低等特点，分析各型航向伏尔下滑功能天线的可实现性。结果表明在小型高机动飞机上无法直接使用现有的航向伏尔下滑天线实现所有性能需求。经过理论分析和半物理试验，开展增加天线搭接的方式，强化低成本小型航向下滑天线的方向性性能，最终实现了飞机需求的高强度、低成本和高性能的伏尔导航功能。

In view of the characteristics of small size, high density of composites, high speed, large maneuver- able strength, and low cost, small and high-powered aircraft, the feasibility of each model course VOR decline in function of the antenna is analyzed. The results show that all performance requirements can not be realized directly by using the existing heading voltage drop antenna on small and high powered aircraft. Through theo- retical analysis and physical testing, the antenna lap method was added, and the directional performance of the low-cost and small ILS antenna was strengthened. Finally, the high strength, low cost, and the high performance VOR navigation function required for the aircraft were achieved.
