Novel method for aero-optic evaluations Conference Paper uri icon


  • The impact of aerodynamic flow upon the performance of an airborne optical system is becoming a critical issue in the development and engineering of IR electro-optic systems. The analysis of this impact is now in the state of the art of IR electro-optic system research. Significant effort has been made on this issue during recent years. In this work we describe a novel technique for aero-optic calculations. The technique is based on commercially available software. In this work CodeV is the optical ray tracing code and Fluent is the Computational Fluid Dynamics (CFD) code. The synergetic combination between the output of the CFD code and optical software leads to the development of the method. The optically relevant data from the CFD results is transformed into index of refraction field and introduced as an input to the optical code. It is important to note that the data must not necessarily be …
