Il-76TD air crash. Aircraft loading evaluation

The purpose of the paper was to study the accidental collision of the Il-76TD aircraft flying at speeds of up to240 m/s with an obstacle, and the condition of dangerous goods being transported. According to the results of calculations, comparisons with the available analytical solutions and data on real accidents, we developed a prediction model of the IL-76TD aircraft, the model reflecting the aircraft mass-dimensional and power characteristics. Furthermore, we estimated the parameters of the load pulse acting on the transported cargo and the impact of the obstacle material on them. The resulting load pulse parameters are the basis for the development of packaging, the design of which should ensure compliance with regulatory safety requirements for the transport of dangerous goods

The Impact

To provide an objective tool for assessing the risks involved in the transport of dangerous goods, a model called RISKMOD-I was developed for Transport Canada by the Institute for Risk Research. The model implements the computational aspects of a comprehensive risk assessment methodology which addresses both the quantitative and qualitative aspects of dangerous goods releases following a transport incident. This paper describes the model's implementation, data requirements, and outputs.The risk assessment model consists of an analysis of link-specific accident rates and a fault tree analysis to determine the probability of a dangerous good release of a particular type. In parallel, a series of commodity-specified damage models compute the impact areas associated with representative sizes and types of releases. The impact areas for each damage threshold are then multiplied by the population density and property exposure along each link to determine the total risk associated with a dangerous goods shipment that uses the link. This estimate of total risk can optimally be further converted into a risk cost value in monetary terms and summarized for the entire route. Both the risk and risk cost estimates are intended to be used in conjunction with other subjective analyses and performance measures to provide a comprehensive decision-making aid for risk managers. Key words: dangerous goods transport, truck and rail accidents, risk analysis.
