Abstract

The technology of bending–rolling in rollers of shaped aircraft parts is proposed and implemented by the pilot straightening–bending installation in AO Ulyanovsk NIAT. Experimental results are presented for research of longitudinal bending of aircraft part blanks made of formed sections. The data obtained demonstrates the possibility of obtaining the workpieces with a radius of curvature less than 600 mm from high-strength aluminum alloys while preserving the profile cross-section parameters.

飞机异形件纵向弯曲和矫直技术的改进

摘要

在AO Ulyanovsk NIAT的飞行员校直-弯曲装置中提出并实施了飞机异型件的滚子弯曲-滚动技术。提出了实验结果，用于研究由成形型材制成的飞机零件毛坯的纵向弯曲。所获得的数据表明，在保持轮廓横截面参数的同时，可以从高强度铝合金获得曲率半径小于600 mm的工件。
