六二一研究所和三七○厂共同完成的“15-1混炼胶和607-1胶液及其粘接工艺”,于一九八四年二月下旬通过部级技术鉴定。涡轴六发动机离心式压气机的离心叶轮组合,是由导风轮(2Cr13不锈钢)和叶轮(LD7铝合金)组成,在导风轮和叶轮叶片对接处粘接胶条。如果胶条脱落,将引起发动机振动,出现明显噪音,并影响发动机温度场的分布,T_4温度增高,进而影响自由涡轮和燃气涡轮的工作寿命。兄弟单位曾以F-7-6氟橡胶
June 21 Institute and the March 30 factory jointly completed “15-1 rubber and 607-1 glue and bonding process”, in late February 1984 through ministerial technical appraisal. Centrifugal centrifugal turbines turboshaft centrifugal combination of six impeller, is composed of wind guide wheel (2Cr13 stainless steel) and the impeller (LD7 aluminum alloy), the wind turbine and impeller blades at the junction of adhesive tape. If the rubber strip off, it will cause the engine vibration, significant noise, and affect the distribution of the engine temperature field, T_4 temperature increases, thus affecting the working life of free turbines and gas turbines.
