Design and Realization of Unmanned Airship Simulation System

This paper presents a flight and load synchronization airship simulation system architecture which is modular and scalable, and builds a system of real through aerodynamic estimation, CFD calculation, dynamic modeling, control law design, image pretreatment, lens simulation, video coding, information compound and other links. In order to improve the accuracy of numerical modeling, this paper adopts CFD calculations to verify and correct engineering estimation method; besides, this paper adopts the image preprocessing technology based on TMS model and lens control technology based on OSG Earth to enhance the real-time and fidelity of photoelectric load simulation; in this paper, video coding which is based on FFmpeg uses GPU parallel processing to improve the system real-time. Test results show the consistency of the simulation output with the actual airship flight and the payload, which is of great practical value.
