As an outer covering of cooling aircraft engines, the air intake cover very much effects the aerodynamic performance of the aircraft under the condition of high-speed air current striking on it. In order to improve the aircraft's aerodynamic performance, the temperature field distribution of the gypsum-based Investment casting process of the air intake cover was analyzed by ANSYS software, which the Pro/E software was used as the three-dimensional modeling software. In the modeling process with Pro/E software, three default datums must be firstly established. In the same time, it is necessary to appropriately use some temporary datums. Some functions, such as Protrusion> Use Quilt> Solid or Thin,Reorder,Redefine,Reroute, are very important to generate complex curved surfaces and entities. The results of the temperature field simulation showed that the process of filling and solidification reflected the actual casting situations, forecast possible defects in casting and defective locations of the castings, order solidification was obtained which a rising head was put close to casting heat knots and final solidification positions, and ensured the feasibility and quality of the air intake cover casting.
