METHODOLOGY FOR ASSESSING THE OPERATIONAL SAFETY OF AMMUNITION WITH EXPLOSIVES THAT ARE INSENSITIVE TO EXTERNAL THERMAL INFLUENCES
Abstract
Background. The relevance of the article is due to its practical significance for solving the problems of operational safety of ammunition located at storage facilities, when it is necessary to know the time of explosion of products. The article proposes a developed analytical model for determining the permissible exposure time for ammunition to damaging environmental factors (lightning and landscape fire). Materials and methods. Modeling of the process of emergency situations during the explosion of standard or promising ammunition with low-sensitivity explosive compositions under external thermal influence can be described by a Markov random process scheme with a countable number of states. The use of the Markov model makes it possible to apply a well-developed and proven mathematical apparatus and obtain a deliberately reliable result due to the rather strict restrictions adopted. Results and conclusions. Thus, the developed analytical model for determining the permissible exposure time for ammunition to damaging environmental factors can be used to predict the operational safety of products in storage or in the assembly and repair production of arsenals for complex storage of missiles and ammunition. The obtained algorithm for determining the permissible time of exposure to damaging environmental factors on ammunition is advisable to use in the development of promising ammunition with low-sensitivity explosive compositions.
