Development of a method for assessing ther-mal stresses in structural elements of aircraft




A 2D computational-theoretical technique (on a structured computational grid) has been de-veloped that makes it possible to find a solution to a system of equations of linear thermoe-lasticity with boundary conditions of a general form for key elements of an aircraft moving at supersonic and hypersonic speeds in the Earth's atmosphere. It is assumed in the work that the effect of coupling between the deformation and temperature fields is small.

Разработка методики оценки термонапря-жений в элементах конструкции летательных аппаратов

Разработана 2D расчетно-теоретическая методика (для структурированной расчетной сетки), позволяющая находить решение системы уравнений линейной термоупругости с граничными условиями общего вида для ключевых элементов летательного аппарата, двигающегося со сверхзвуковой и гиперзвуковой скоростью в атмосфере Земли. В ра-боте принято, что эффект связанности полей деформации и температуры мал.
