Ticari Uçuşların İniş ve Kalkış Döngüsü Sırasında Çevresel Etkilerinin Belirlenmesi

Öz

Bu çalışmanın amacı ticari uçuşların neden olduğu hidrokarbon (HC), karbonmonoksit (CO), karbondioksit (CO2), nitrojen oksit (NOx) emisyonlarının ve bu emisyonların küresel ısınma potansiyelinin belirlenmesidir. Çevresel etkiler hava araçlarının iniş ve kalkış döngüsü için hesaplanmış ve küresel ısınma potansiyeli üzerine etkileri belirlenmiştir. 22 farklı model hava aracının LTO döngüsündeki çevresel etkileri ve küresel ısınma potansiyeline etkisi hesaplanmıştır. Yakıt tüketimi, HC ve CO emisyonlarının taksi fazında en yüksek değere ulaştığı görülmüştür. NOx emisyonlarının ise tırmanma fazında en yüksek değere ulaştığı belirlenmiştir. Taksi süresinin 2 dakika kısalması ile HC ve CO emisyonlarının yaklaşık %7 azaltılabileceği sonucuna varılmıştır. LTO döngüsünde tırmanma fazının küresel ısınma potansiyeli üzerine etkisi %40 ile en yüksektir.

Determination of Environmental Impacts Of Commercial Flights During the Landing and Take-off Cycle

Abstract

The aim of this study is to determine the hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx) emissions caused by commercial flights and the global warming potential of these emissions. Environmental effects were calculated for the landing and take-off (LTO) cycles of aircraft and their effects on global warming potential were determined. The environmental impacts of 22 different models of aircraft in the LTO cycle and their impact on global warming potential were calculated. Fuel consumption, HC and CO emissions reached the highest value in the taxi phase. It was determined that NOx emissions reached the highest value in the climb-out phase. It is concluded that HC and CO emissions can be reduced approximately 7% by shortening the taxi time by 2 minutes. It has been calculated that the effect of the climb-out phase on the global warming potential in the LTO cycle is the highest with 40%.
