Keywords: rain, aerodynamic analysis, aviation safety

This paper first reviewed some research finding of heavy rain effects on aerodynamic performance degradation. Then a computational method to compute the two-dimensional heavy rain condition is introduced and the effects of droplet cratering, liquid water content, droplet terminal velocity, air density modification are included.
