A proposed hybrid-electric plane could “eliminate aviation’s air pollution problem,” say MIT engineers. Their design could reduce global nitrogen oxide (NOx) emissions by 95 percent, they report in a study.  Today’s planes are propelled by jet engines anchored beneath each wing. Each engine houses a gas turbine that powers a propeller to move the plane through the air as exhaust from the turbine flows out the back. Due to this configuration, it has not been possible to use emissions-control devices, as they would interfere with the thrust produced by the engines. In the new hybrid-electric, or “turbo-electric,” design, a plane’s source of power would still be a conventional gas turbine, but it would be integrated within the plane’s cargo hold. Tracking Toxic Plane Pollution. Barrett and colleagues used a computer model that brought together records of flight paths, the average amount of fuel burned during flights, and their estimated emissions. The computer model, based on experimental data, has been shown to accurately capture pollution's movement in the atmosphere as well as Jet Plane Pollution Controls intercontinental transport of pollution, especially from Jet Plane Pollution Chart Asia to North America, Barrett said.  Airplane pollution deaths still represent Jet Plane Pollution Github a small share of the toll from all kinds of air pollution.  Sulfur in jet fuel is a major killer, but for a small additional cost "on the order of [U.S.] five cents a gallon, you can remove the vast majority of the sulfur," he said. Универсальный англо-русский словарь. jet pollution. Толкование Перевод. jet pollution. 1) Медицина: выбросы от реактивных самолётов, загрязнение среды выбросами от реактивных самолётов. 2) Техника: выброс от реактивных самолётов, загрязнение выбросами от реактивных самолётов. 3) Экология: загрязнение от реактивных самолётов. Универсальный англо-русский словарь. www.- Following more than a decade of petitions and successful litigation by the Center and allies over the Environmental Protection Agency’s failure address the effects of aircraft pollution under the Clean Air Act, in the EPA made a formal finding that greenhouse gas pollution from aircraft endangers human health and welfare. A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines.. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of www.- aircraft generally cruise most efficiently at about Mach. Jul 19,  · The figures include only the CO2 generated by burning jet fuel, not any emissions embedded in the construction of the plane or any other greenhouse gases .
Aircraft engines emit ultrafine particles UFPs in and near airports, as does ground support equipment. According to studies, night flights cause global warming more compared to day flights because contrails help in reflecting sunlight during the day.

Pollutants damage the quality of air, water, and land. Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere.
