A New Method to Analyze the Thermal Effect due to Plume Impingement on Communication Satellites

Abstract:

Data fitting approach based on test data is commonly adopted on analyzing of thermal effect due to the thruster plume impingement on communication satellites, however, the existing methods are only available for the appendages which are regularly shaped or could be formulated. In this paper, a plume impingement analyzing approach for irregularly shaped appendages is present. The STL (Stereo Lithographic) data is firstly derived from the three-dimensional model of the appendages. Then the STL data are made a kind of interpolation to get small particle size in order to obtain a precise analyzing result. Finally, the normal vector and the location of each triangle grid are obtained from the STL data to form a new model for plume impingement analyzing on irregularly shaped appendages. The new method is proved correct by comparing with PLUME software and the method given in [4].The application range of analyzing exhaust plume impingement on communication satellites can be widely extended by the proposed method.
