| Abstract: |
| In this paper,a computational method for predicting the aero-heating environment for key places of hypersonic aircrafts is presented.Based on the reference enthalpy method,the classical heat flux formulae are used to determine the surface aero-dynamic heating.Then,an algorithm for hypersonic aerodynamic heating environment is developed.Using this method,heating rates for some simple blunted cone shapes of aircrafts are calculated.The computational results show the high accuracy comparing to the existing experimental data. |
