Modeling and control analysis of URRG Monohull Blimp

This paper describes the design of a non rigid airship with the issue of scaling down the size. Nevertheless, the stability and controllability of the airship are significant mainly due to drag and buoyancy forces. These problems can be solved by introducing a proper structure design and reliable control algorithm. In this paper, we proposed an airship design called as "Blimp". We have described the analysis of motion characteristics without ballonet and the model was characterized based on URRG platform setup. Using the computational fluid dynamic approach (CFD), the aerodynamic coefficients were produced by FLUENT™ package based on geometry meshing using GAMBIT™. The blimp model has been proven to be controllable through implementation of an optimal controller for solving the lateral model navigation issues. Simulation within a range of data reveals that the design achieved the desired motion behavior, thus verified its efficiency and viability.
