摘要

FIELD: aircraft meteorology; estimation of conditions of forming aircraft condensation trails. ^ SUBSTANCE: proposed method consists in measurement of atmospheric air parameters in air route: pressure, temperature and relative humidity. Temperature gradient of mixing line is measured as well. Then, threshold magnitude of temperature corresponding to maximum super-saturation of steam in mixed jet relative to its saturated magnitude at definite temperature is calculated. Proposed method includes also measurement of difference of partial pressures of steam in mixed jet and saturated steam above water at threshold magnitude of temperature and quantitative criterion - super-saturation factor is formed. Quantitative estimation of conditions of forming condensation trails is determined by total magnitude and sign of super-saturation factor. ^ EFFECT: enhanced accuracy of estimation. ^ 3 cl, 3 dwg
