Прогнозирование динамики и мореходных качеств амфибийных судов на воздушной подушке

Abstract

Annotation – The creation of hovercraft projects is a very expensive procedure, and the emergence of new ships of this type and their evolution is proceeding at a very slow pace. Despite the fact that hovercraft have been used for decades and there is a large amount of literature that is related to the theory of such ships and the practice of their design, there are still a number of unresolved problems associated with these ships. There are various methods, theories and publications that allow to calculate and design various complexes and systems of hovercraft, and as a result, this allows to create vessels that are successful in operation and with good seaworthiness. But at the same time, until now, the main problem remains to achieve sufficient accuracy in predicting the operational characteristics of hovercraft under various modes. Therefore, it is not uncommon for a successful hovercraft project to be born after a series of unsuccessful trial and error. The presented work describes a methodology for creating simulations of hovercraft for various modes of their operation. Various types of simulations of such ships and the ways of their implementation into functioning software are considered. The main mathematical models that are involved in the implementation of such simulations are described and their structure is shown for various hovercraft. The described complex of mathematical models, embodied in the program, allows an in-depth analysis of the dynamics and operational characteristics of hovercraft before the completion of their design and before the start of construction. It is argued that the most difficult, but suitable for real practical problems of analyzing the dynamics of hovercraft is the simulation of this ship with 6 degrees of freedom. The study allows us to conclude that the described methodology for creating a complex of mathematical models makes it possible with high accuracy to predict the dynamics of hovercraft and simulate any hovercraft with 6 degrees of freedom, which will reduce the cost of designing and building a lead hovercraft with accurately predictable seaworthiness and operational characteristics.
