民用航空发动机滑油投入航线运行前工程鉴定试验研究

截止2019年年底，中国民航现有固定翼运输类机队规模约3 800架，发动机约7 600台，以航线统计的发动机平均滑耗0.23夸脱/小时进行估算，滑油年消耗量不少于5 200万夸脱，估值约7.9亿元人民币。现阶段，我国民用航空发动机滑油严重依赖进口，显然不利于航空工业的健康成长。因此加速国产滑油适航取证并投入航线运营的工作，不但能够解决我国民用客机长期对进口滑油的依赖，更具备广阔的市场前景和经济战略价值。随着民用航空设备和部件的国产化进程加速，国产滑油的技术指标已经达到同行业领先水平。由于国内现有民航飞机发动机均为国外制造，同时受限于现行国际通用的民用航空滑油取证体系，我国自主研制的滑油适航取证面临诸多困难。对民用航空发动机滑油投入航线运行前所需开展的鉴定试验进行研究，用于支持和推进我国自主研制的滑油油料尽快投入航线使用。

Certification method for civil turbine engine oil

By the end of 2019, CAAC has a fixed-wing transport fleet of about 3,800 aircraft and about 7,600 engines. Based on the average engine consume of 0.23 quart / h, the annual oil consumption is no less than 52 million quarts, with an estimated value of about 790 million RMB. At present, domestic civil aviation engine lubricating oil is heavily dependent on imports, which is obviously not conducive to the healthy growth of the aviation industry. Therefore, accelerating the work of obtaining airworthiness certification of domestically-made lubricants and putting them into market can not only solve the long-term dependence of our civil aircraft on imported lubricants, but also have broad market prospects and economic strategic value. With the acceleration of the localization process of civil aviation equipment and components, the performance of domestically-made lubricants have reached the leading level in the same industry. Since the domestic civil aviation aircraft engines are all manufactured abroad and are limited by the current internationally accepted civil aviation oil certification system, domestic self-developed lubricants are facing many difficulties in obtaining airworthiness certification. This paper studies the qualification tests required for civil aviation engine lubricating oil before it is put into service, so as to support and promote the lubricating oil certification as soon as possible.
