100LL 低铅航空活塞式发动机燃料国产化研究与应用

摘要

To meet the requirements of environmental protection and standards and performance of a new kind of general aircraft fuel,the performance of compositions of aviation fuel were investigated, resulting in low lead aviation gasoline,which meets the standard of 100LL of ASTM D910—2013 and realizes the industrial trial production. Flight tests indicate that the performance of the new developed fuel is similar to the product of the United States. The developed aviation fuel has the characteristics of good evaporation,ignitability,stable properties and low crystallization point. No corrosion to engine parts is observed. The technology fills a domestic gap in this field with broad prospect.%为满足环保要求和新型通用飞机对燃油标准和性能提出的更高要求，系统考察了航空汽油基础油品组分的性能，开发出了符合 ASTM D910—2013标准中100LL 规格的低铅航空活塞式发动机燃料（简称低铅航空汽油），并实现了工业化试生产。飞行试验结果表明，新开发的低铅航空汽油性能与美国同类产品相当，具有蒸发性能好、易燃、性质稳定、结晶点低和不腐蚀发动机零部件的特点，应用前景广阔。
