The Plume Infrared Radiation Based on Visualization Computing

Abstract

The infrared radiation of plume has a great influence on the aircraft stealthy performance. The research of plume is mainly on plume modeling and plume infrared radiation calculation. To obtain a more vividly plume calculation process and more precise results, this paper combines the traditional geometric approximate modeling method and Curtis-Godson(C-G) approximate method by OpenGL to realize the plume infrared radiation visualization computing. A realistic plume model and an advanced C-G method are proposed. Two experiments results validate the effectiveness of this method.
