  • Martian atmosphere which is quite different from Earth atmosphere plays an important role for Mars entry vehicles.Therefore aerodynamic predictions for trajectory design and layout optimization should be settled firstly.Three-dimensional Navier-Stokes equations with real gas model and ideal gas model have been solved by a parallel code to analyze the impact of different models on aerodynamic characteristics,to obtain accurate,efficient and reliable model for aerodynamic predictions.The good agreement among the numerical results,the reference values and the flight data of Viking along the trajectory validates the real gas physical-chemical models and the numerical methods applied.Using real gas model and ideal gas model,aerodynamic characteristics of lift-entry Viking and zero angle of attack Mars Pathfinder have been predicted.The results show that predicts value of ideal gas model with effective specific heat ratio is very close to that of the real gas model, the deviation is about 1%,and the difference of the trim angle of attack is about 0.4°.Prediction of ideal gas with specific heat ratio from inflow temperature shows a large deviation.Real gas model and ideal gas model with effective specific heat ratio are suggested in aerodynamic characteristics predictions of Mars entry.
