A new study warns that India of the Capital New Delhi Arriving at the main airport of Planes are absorbing large amounts of dust that can accumulate in their engines over time, putting them at serious risk of breakdown.
The research, which is yet to be peer-reviewed, recommends that more flights at Indira Gandhi International Airport be scheduled at night to reduce engine damage from dust emissions by regarding a third. can be reduced to
Claire Ryder, of the University of Reading in the UK and lead author of the study, said: ‘Dust and sand are dangerous to aircraft because they melt and deposit a glassy layer on the blades or cause deposits of hard mineral crusts. are made Crusts disrupt airflow and cause overheating, which in turn causes the engine to over-thrust.’
He added: ‘Although the amount of dust introduced per flight is not very high, it accumulates quickly. An aircraft that swallows five grams of dust during each arrival and departure accumulates 10 kilograms of dust following 1,000 flights.
Researchers analyzed nearly two decades of satellite and atmospheric data to calculate aircraft dust at some of the world’s busiest airports.

The study, published this week in the journal Natural Hazards, shows that the largest amounts of dust are absorbed by aircraft during dust storms in the Sahara desert, the Middle East and northern India.
The scientists warned that ‘Mineral dust aerosols in the atmosphere can cause danger to aircraft by settling on internal engine parts.
According to research, planes landing in New Delhi during the summer absorb the most dust, accumulating an average of 6.6 grams per arrival and more than four grams per departure. In second place is Niger’s Niamey Airport, where planes absorb 4.7 grams per landing. It is followed by Dubai where it averages 4.3 grams.
The researchers also found that planes hovering over these airports while waiting for landing permission pick up more dust.
Waiting 10 to 15 minutes for a landing at an altitude of one kilometer can lead to more dust absorption than the take-off and altitude gain phases of a flight, the researchers said.
The researchers also found that circling the Delhi airport at a height of one kilometer during summer contributes 50 percent to the dust collection process.
Shifting flight landings in Delhi and Dubai to nighttime might reduce engine dust emissions by nearly a third, research suggests.
Researchers predict that climate change, along with rising temperatures and expanding deserts, might lead to more dust in the world.
But current climate models disagree because dust emissions depend on many factors, including rainfall, soil moisture, surface wind patterns and vegetation cover.
