| titleOfInvention | Three-dimensional complex-shape high-speed aircraft flow-solid-heat rapid calculation method |
| abstract | The invention discloses a quick calculation method for flow-solid-heat of a three-dimensional high-speed aircraft with a complex shape, and belongs to the field of aerodynamic calculation of aircrafts. According to the boundary layer theory, the method combining CFD numerical calculation and an engineering algorithm is adopted, the calculation of static aerodynamic heat is simplified into two parts of inviscid outflow numerical solution around the aircraft and heat flow solution in the boundary layer, and meanwhile, a heat transfer calculation model of the heat protection system structure is coupled. The method combines the advantages of full-length numerical simulation and the engineering algorithm, can quickly and efficiently calculate the pneumatic heating and structural coupling heat transfer characteristics of the three-dimensional high-speed aircraft with complex appearance in various flight states, gives the time-varying characteristics of the surface heat flux density and the heat-proof structure temperature field of the aircraft, overcomes the defects of high calculation cost, low efficiency, long period and the like of a direct numerical simulation method, and expands the application range of the engineering algorithm. |
