成都飞机维修公司(CAMEC)承修的-30Ky-154低涵道比双转子涡扇发动机是前苏制图-154M客机的动力装置,推力为10294十牛。按照大修手册要求,翻修过程中需使用300多项前苏联的辅助材料。若这些材料全部从俄罗斯进口,存在以下问题:1.订货周期长,而且供货合同执行信誉差,不利于保证发动机的正常翻修周期;2.报价甚高,1990年仅32项订货就耗资人民币47万元,造成维修成本直线上升,增加航空公司费用;3.相当数量的辅助材料有效存放期短。根据对油(脂)、漆料、化学品三类辅料的不完全统计,有效期为1～6个月的占21.1％;有效期为7～12个月的占37.4％。而正常情况下跨国铁路运输一般为3～6个月,即部分辅助材料运到CAMEC时就已超期不能使用;4.有的辅助材料不能用铁路或飞机运输。因此,开展辅助材料代用研究势在必行。
Chengdu-based aircraft maintenance company (CAMEC) contractor -30Ky-154 low bypass ratio dual-rotor turbofan engine is the Soviet-made map -154M passenger aircraft power plant, the thrust of 10294 ten cattle. In accordance with the overhaul manual requirements, the renovation process requires the use of more than 300 former Soviet auxiliary materials. If all these materials are imported from Russia, there are the following problems: 1. The long period of ordering and the poor reputation of the delivery contract are not conducive to guaranteeing the normal renovations of the engine. 2. The quotation is very high. In 1990, only 32 orders cost Renminbi 470000 yuan, causing the cost of maintenance straight up, increasing the cost of airlines; 3. A considerable number of auxiliary materials effective storage period is short. According to the incomplete statistics of the three kinds of excipients (oil, grease, paint, chemicals), the effective period is 1 to 6 months, accounting for 21.1%; the effective period is 7 to 12 months, accounting for 37.4%. Under normal circumstances, transnational rail transport is generally 3 to 6 months, that is, some auxiliary materials have been extended to CAMEC expired can not be used; 4. Some auxiliary materials can not be transported by rail or aircraft. Therefore, it is imperative to carry out the research of auxiliary material substitution.
