AI Technical Summary
Technical Problem
Existing verification methods for drone horizontal tail absorbing structures are costly and time-consuming, affecting the speed of project design iteration.
Method used
A composite prototype model was adopted, which was constructed using a flat plate and a flat tail made of metal. It was rotated on a test turntable with foam support to conduct RCS tests, determine the final design scheme, and simplify the verification process.
Benefits of technology
This enabled rapid and low-cost verification of the flat-tail absorbing structure, shortening the development cycle and improving testing efficiency.

Abstract
本发明公开了一种无人机平尾吸波结构快速验证方法，包括：确定无人机平尾侧向雷达散射影响区域，其中，将无人机的尾舱体与平尾整体作为侧向雷达散射影响区域，设计平板结构来替代尾舱体；对平尾的侧向雷达散射影响区域简化并建立组合样件模型；基于建立的组合样件模型开展平尾吸波性能测试，以确定最终的平尾设计方案。本发明方法试件结构相对于全弹简单、尺寸小，可以一次加工多块配合多方案吸波结构平尾备用，研制周期短，需求经费少。由于试件精度高，可以采用多块多状态加工同时测试的方式，这样在测试间隔只需要换试验件就实现状态更换，从而提高了测试效率。
