Некоторые проблемы моделирования аппаратов на воздушной подушке

Н. М. Шерыхалина, Е. Р. Шаймарданова

В статье рассматривается расчет аэродинамики потоков воздушного пространства для различных типов моделей судов на воздушной подушке. Рассмотрена статическая устойчивость, а также описаны различные режимы течения воздушной струи, которые характеризуются коэффициентом расщепления струи, равным отношению расхода, поступающего в зону с повышенным давлением, к общему расходу. Предложена аппроксимация результатов точных расчетов и применение аппроксимационной формулы в математической модели судна на воздушной подушке на основе результатов численных исследований. В качестве примера рассмотрена аппроксимация силы давления стенки сопла на поток в задаче течения от сопла с удаленной внутренней стенкой. Подчеркивается, что формулы, выведенные из приближенных теорий, пригодны для инженерных расчетов судов на воздушной подушке, в отличие от методов, опирающихся на точные решения задачи. Описанные подходы позволяют строить математические модели процессов движения судна на воздушной подушке, которые в достаточной степени соответствуют экспериментальным данным.


Ключевые слова


Аэродинамика, судно на воздушной подушке, математическая модель течения воздушной струи, схема камеры, схема струи, статическая устойчивость, гибкое ограждение.
