This paper analyzes the deflections of the ice cover caused by the combined action of the impact load and the subsequent decelerating load during airplane landing. It analyzes the influence of the impact load and the thickness of the ice cover on the possibility of the safe use of the ice cover as a runway. It was found that the impact load produces a deflection with a magnitude no greater than that produced when the decelerating load passes through the critical speed.
In several countries there has been in recent years increasing interest in the Arctic shelf due to its huge amount of natural resources. It is therefore necessary to create regular navigation to these remote areas. The use of airplanes increases the possibilities of the exploration and development of remote polar regions. Cargoes and equipment for the Russian Arctic expeditions are delivered by The Ministry of Emergency Situation through the use of the IL- 76TD and An-74 airplanes by The Utair Aviation. Over the years, the Antarctic station McMurdo has been provisioned through the use of the C-130 Hercules airplane (Squire et al., 1996; Milinazzo et al., 1995). Building airfields in these regions is difficult, however, and requires considerable economic expense. The use of the ice cover as a runway can reduce this expense.
Landing is a difficult and dangerous flight maneuver. At the moment when the undercarriage touches the runway surface, the most intense loading of the ice cover occurs. This can lead to the destruction of the ice cover. Therefore, it is necessary to define the parameters of the ice airfield to enable safe air navigation.
The problem of load motion on the floating ice plate is being examined widely and developed actively in the present scientific world due to extensive applications to the creation of an artificial platform for different purposes, the destruction of the ice cover, and so forth. The works of Kheisin (1967), Kerr (1976), and Squire et al. (1996) are fundamental in this field. Milinazzo et al. (1995) considered the steady motion of a rectangular load on a floating ice plate. Schulkes and Sneyd (1988) studied ice plate deflections caused by a suddenly starting line load. Nugroho et al. (1999) and Wang et al. (2004) investigated the time-dependent response of a floating elastic and viscoelastic plate to an impulsively started moving load. Miles and Sneyd (2003) considered an accelerating line load on an elastic plate.
