METHOD OF PREDICTING QUANTITATIVE PARAMETERS OF CONDENSATION TRAILS EMITTED BY AIRCRAFT ENGINES FOR ESTIMATION OF THEIR COMPLIANCE WITH PERMISIBLE ECOLOGICAL LEVEL OF EMISSIONS Russian patent published in 2007 - IPC G01W1/02

Abstract RU 2312379 C9

FIELD: aviation and ecology; environmental control.

SUBSTANCE: proposed method consists in measurement of altitude H in cruising flights, pressure P, temperature t_HB, partial pressure steam contained in atmospheric air e_HB, turbine exhaust gas temperature t_t and rotational speed of engine, calculation of temperature gradient of moisture mixed with exhaust jet B₀. Besides that, magnitude of quantitative parameter of steam super-saturation in mixed exhaust jet of engine is calculated by definite formula.

EFFECT: possibility of normalizing of quantitative characteristics of condensation trails depending on their effect on radiation balance of atmosphere and ground surface for reduction of content of carbon dioxide in exhaust jet of aircraft engine.
