Aircraft dynamics during flight in icing conditions

Grzegorz Kowaleczko, Michał Wachłaczenko
This paper presents numerical analysis of airplane motion parameters during wing in-flight icing. The wing external flaps deflection event was taken under consideration. The mathematical model of the airplane motion including twelve ordinary differential equations was employed. Using available publications as well as TS-11 ``Iskra'' jet trainer geometrical and mass relationships, a computer code evaluating motion parameters of an iced airplane was developed. On the basis of analysis results, conclusions referring airplane dynamic properties during wing ice accretion was formulated.
