一、引言整体叶盘(Blisk)是现代航空发动机的一种新型结构,它将发动机转子的叶片与轮盘进行整体设计与制造。与传统结构相比,由于省去了起连接与固定作用的榫头、榫槽和锁紧装置(如图1),整体叶盘具有如下优点:叶盘的轮缘径向高度、厚度及叶片原榫头部位尺寸均减小,显著减轻了转子的质量;零件数量大量减少,转子结构大为简化,有利于装配和平衡,使发动机的可靠性增加;在传统的叶片和轮盘连接方式中,榫头和榫槽之间
I. INTRODUCTION The overall Blisk is a new type of modern aeroengine that integrates the design and manufacture of the blades and discs of an engine rotor. Compared with the conventional structure, the integral leaf disk has the following advantages due to omission of the tenon, tongue and groove and the locking device (as shown in FIG. 1) that are used for connection and fixation. The radial height and thickness of the leaf disk rim, The size of the tenon parts are reduced, significantly reducing the quality of the rotor; a substantial reduction in the number of parts, the rotor structure is greatly simplified, which is conducive to assembly and balance, so that the reliability of the engine increases; traditional blade and roulette connection, the tenon And between the tongue and groove
