Notes:
This study is conducted in order to estimate the structural characteristics for inlet port of airbreathing engine under flight condition at 12 ~ 15 km height and Mach Number 2 ~ 4. Inlet port of airbreathing engine is heated up from 307 oC to 427 oC, so that is reached plastic zone partially. Thematerial properties at high temperature such as young’s modulus, thermal expansion coefficients andthermal conductivity are applied to the analysis. The transient temperature and stress analysis areperformed by the finite element method using nonlinear commercial code ABAQUS. The analysis isperformed for the two materials, Titanium alloy and AISI4130 Steel and two FEM element type, shelland solid, to select preliminary design model for flight condition. Thermal boundary conditions areapplied at inlet port until 5 s, and these conditions are maintained until 150 s. The results of theanalysis recommend tendency of thermal stress and temperature contour. This study is expecteduseful to select the structural material and to determine shape of air inlet port of air breathing enginewhich satisfied the structural design safety
