为提高航空发动机总体性能、改善发动机热力循环模式,设计一种蒸发式涡轮叶间燃烧室方案,试验研究不同油气比下叶间燃烧性能的变化规律;利用数值计算获得燃烧室内燃油分布、组分分布等参数对燃烧性能的影响.研究结果表明:在导向器叶片叶间通道内利用蒸发式稳定器可有效促进燃油雾化以及稳定燃烧,涡轮叶间燃烧室在试验条件下最大温升为 694.4 K,燃烧效率为 90.3%.
Study on Scheme and Performance of Evaporative Turbine Inter-blade Combustor
In order to improve the overall performance and thermodynamic cycle mode of aero-engine,an evaporative turbine inter-blade combustion scheme was designed,and the combustion performance changes of the inter-blade combustor under different oil/gas ratios were studied experimentally.Parameters such as fuel distribution and component distribution in the combustor were obtained by numerical calculation.The results show that fuel atomization and stable combustion can be effectively promoted by using evaporative stabilizer in the inter-blade channel of the turbine guide.The maximum temperature rise of the inter-blade combustor is 694.4 K under test conditions,and the combustion efficiency is 90.3%.
