一、Ws—6型航空发动机钛合金叶片的设计原则和工艺特性介绍Ws—6型发动机是我国于一九七九年自行研制的第一台高推力重量比的涡轮风扇喷气发动机。其第一、二级风扇叶片采用钛合金材料、牌号为 BK—16。风扇叶片安装板(指根部)为燕尾形台、顶部为梯形板叶盆、叶背带二个阻尼凸台、第一级风扇23个叶片、第二级风扇31个叶片安装在低压压气机转子轮盘上、由低压涡轮来驱动,其转速为8500rpm。第一、二级叶片长×宽分别为550×120mm、365×90mm,截面形状为变截面的翼剖面(沿叶身
I. Design Principles and Process Characteristics of Ws-6 Aero-engine Titanium Alloy Blade Introduction The Ws-6 engine is the first turbofan jet engine developed by our country in 1979 with high thrust and weight ratio. The first and second fan blades made of titanium alloy, grade BK-16. The fan blade mounting plate (referring to the root) is a dovetail-shaped platform with a trapezoidal blade top plate at the top and two damping bosses with leaf straps. The first stage fan has 23 blades and the second stage fan has 31 blades mounted on the low-pressure compressor rotor wheel Plate, driven by a low-pressure turbine, the speed of 8500rpm. The first and second leaves are 550 × 120mm in length and width, 365 × 90mm in length,
