Abstract

The invention relates to the technical field of aerospace, in particular to a method and device for measuring the emission load of aircraft engine emissions. The method comprises the steps of acquiring four-dimensional data and corresponding meteorological data of an aircraft in the flight process wherein the four-dimensional data comprise longitude and latitude, height and flight time of the aircraft; based on the four-dimensional data of the aircraft, determining the fuel consumption rate of the height of the aircraft; determining an emission factor of the emissions according to the types ofthe emissions and the four-dimensional data and meteorological data of the aircraft; and according to the flight time of the aircraft, the fuel consumption rate of the height of the aircraft and theemission factor, obtaining the emission load of the engine emissions of the aircraft. The invention is more accurate in measured data, and provides a powerful data guarantee for the control of the emission load of the aircraft.

Description

technical field [0001] The present disclosure relates to the field of aerospace technology, in particular to a method and device for measuring the amount of emissions from aircraft engines. Background technique [0002] With the rapid economic development in recent years, the traffic demand for air travel has shown a rapid growth trend. The burning of aviation kerosene by aircraft engines will cause the emission of various pollutants and the burden of carbon dioxide. On the one hand, airplanes are an important source of anthropogenic nitrogen oxides and black carbon emissions in the stratosphere, which will affect atmospheric aerosol radiation. Pollutants discharged at the airport during takeoff and landing of airplanes will deteriorate the surrounding air quality and threaten the health of residents. Good health; on the other hand, aircraft is an important source of carbon dioxide emissions, and as the level of aircraft activity continues to rise, it will become an importa...
