Abstract

This paper deals with the subject of optimisation of turboprop aircraft operations to decrease their environmental footprint. This aircraft category is not at the forefront of optimisation efforts of operators as it supplies lower volumes of traffic and is equipped with the most fuel-efficient technology for missions served on regional markets. The theoretical part of this paper details turboprop aircraft contributions to global CO2 emissions and analyses aspects behind their efficient performance. Further, it provides a thorough assessment of the operational practices that can significantly reduce the environmental footprint of turboprop aircraft operations. For better illustration, some are exemplified in simple case studies. The practical part of this work aimed to quantify the effects of operational optimisation on turboprop aircraft. Based on the theoretical analysis, we established five operational adjustments whose effects can be determined using performance calculations. These calculations have been carried out using ATR 72-600 aircraft as a reference for a specified average turboprop flight. It was found that through operational adjustments, the fuel consumption on an average ATR 72-600 flight can be decreased on the order of 10%. The energy intensity of operations defined in CO2 per revenue passenger kilometre could be nearly halved compared to actual values of the ATR 72-600 fleet.

优化涡轮螺旋桨飞机的运行,以减少其环境足迹
本文讨论了涡桨飞机运行优化的主题,以减少其环境足迹。这类飞机并不是运营商优化工作的重点,因为它提供的交通量较低,并且在区域市场上执行任务时配备了最省油的技术。本文的理论部分详细介绍了涡桨飞机对全球二氧化碳排放的贡献,并分析了其高效性能背后的各个方面。此外,它还提供了一个全面的运营实践评估,可以显著减少涡轮螺旋桨飞机运营的环境足迹。为了更好地说明,在简单的案例研究中举例说明了一些。这项工作的实际部分旨在量化操作优化对涡轮螺旋桨飞机的影响。在理论分析的基础上,我们建立了五种操作调整,它们的效果可以通过性能计算来确定。这些计算是使用atr72 -600飞机作为指定平均涡轮螺旋桨飞机飞行的参考进行的。研究发现,通过操作调整,atr72 -600航班的平均燃油消耗量可降低10%左右。与ATR 72-600机队的实际值相比,以每收入乘客公里二氧化碳计算的运营能源强度可以减少近一半。
