Abstract
In this paper, the author applies the method “Statistical dynamics” to determine the dynamic load of the airplane wheels exerting on the airfield rigid pavements. The value of dynamic load depends on kinematic parameters of the airplane main landing gear, the characteristic of surface roughness by spectrum density estimations of airfield pavement elevation according to Burg's and Welch's methods. Thereby, the dynamic load coefficient of IL96-300 airplane has been determined based on results spectrum density estimations of Cam Ranh airport.
