Based on the information from the Internet the authors decided to reproduce the possible conditions of landing the plane IL-76TD-90VD in Antarctica in their computer experiment using the mathematical modeling system of aircraft flight dynamics (MMS AFD), which is developed and continuously improved in MSTUCA. MMS AFD has already shown its ability to complete such tasks for different aircraft types in various conditions, including IL-76TD, IL-96-300, IL-96T and also slippery runways.For the computational experiments the information from the web sources was used. The authors did not aim to produce a final numerical results, which describe the possible operating conditions. It was expected only to get accurate qualitative results, which can adequately describe the behavior of the airplane IL-76TD-90VD when landing on the slippery runway.So, the authors were able to obtain a typical turn of plane at the end of run and show that the pilot style in these conditions has little effect on the qualitative behavior of the aircraft. The most important factor leading to such maneuvers, lies in the special connection of longitudinal and lateral friction of gear wheels with runway.The authors managed to identify the minimum allowed value of standard friction coefficient of the runway (0,42) which allows a safe landing under crosswind 15 m/s.The results that agree qualitatively with the known situations indicate the possibility for MMS AFD to properly reproduce various cases of aircraft IL-76TD-90VD landing to Antarctica ice airfield and identify any inaccurately knownparameters. На основании информации из интернета авторы приняли решение воспроизвести в вычислительном эксперименте с помощью Системы математического моделирования динамики полета летательных аппаратов (СММ ДП ЛА), разработанной и постоянно совершенствуемой в МГТУ ГА, возможные условия посадки самолета Ил-76ТД-90ВД в Антарктиде. СММ ДП ЛА ранее проявила свои возможности по решению подобных задач для различных типов самолетов в различных условиях, в том числе ...
