摘要
航空运输所带来的污染物排放问题日益引起国际社会的关注,加强航空运输业的节能减排首要问题是建立科学的污染物排放标准。通过对航空器巡航飞行中运动状态的研究,给出了长程巡航速度的计算方法,并根据国际民航组织提供的污染物排放系数,推导出巡航阶段最低的污染物排放量计算公式。通过实际算例,对比分析了不同运行方式下污染物排放量的差异,证明长航程巡航方式下的排放量最少,可以作为衡量航班飞行中节能减排效果的基准。
Pollution emission problem of air transportation is being paid more and more attention by international society. The foremost problem of energy saving and emission reduction of air transportation is to establish the scientific standard of pollution emission. This paper presents a speed calculation method of long range cruising through movement state analysis. According to the pollution emission coefficient provided by ICAO, this paper deduces a minimum pollution calculation formula for cruising state. The actual example compares the quantity difference of pollution emission between different operation manners and proves that the most minimum pollution emission amount is achieved under LRC. The re sult can be used as a standard to measure the effect of energy saving and emission reduction during flight.
