摘要

本文介绍了发生在捷克武装部队的航空事故后一年的研究。在这次事故中,米-171直升机严重受损。本文分析了米-171直升机主起落架在着陆过程中发生故障的部件的材料和几何特性。主齿轮包含一个水平前支杆,通过万向节形式的耦合元件安装到机身上。这个接头的故障是这次事故的最终原因。本文比较了捷克厂家和前苏联厂家生产的接头的质量性能。

Analysis of the Damaged Aircraft Component after Impact Caused by Harsh Landing
This paper presents a year-long research after the aviation accident, which happened in the Czech Armed Forces. During this accident, the helicopter Mi-171 was severely damaged. This paper contains an analysis of the material and geometric properties of the part of the helicopter’s Mi-171 main gear, which failed during landing. The main gear contains a horizontal front strut, which is mounted to the fuselage via a coupling element in form of a cardan joint. The failure of this joint was ultimately responsible for the accident. This paper compares the qualitative properties of the joint manufactured by the Czech manufacturer and a former Soviet Union one.
