Modeling of stratosphere airship
The dynamics and kinematics model is very important for the analysis of stability, manipulation and control of stratosphere airship. A full modeling approach that includes the computation of aerodynamics of airship and the added mass for the nonlinear dynamics simulation of stratosphere airships is proposed in this paper. In this approach, the aerodynamics of airship is calculated based on a panel method, an engineering estimation and theory approach. A new numerical method for calculating added masses of airship is developed by using the CFD method. This model can simulate the motion of stratosphere airships quickly and accurately.
Airship dynamic modeling for autonomous operation
We present a comprehensive description of the physical principles of robotic airship operation, along with their dynamic model in a form suited for controller design and computer simulation. Based on the dynamic model, airship response modes are analyzed and control challenges are pointed out. The present work provides a starting point for robotics and control researchers interested in utilizing airships as robotic aerial vehicles.
A comparison of a nonlinear flight dynamic simulation of an airship with flight test results
A six degree of freedom nonlinear airship flight dynamic simulation program has been adapted to apply to nonrigid airships. This report discusses the physical and aerodynamic models that underlie the simulation. The principle of the simulation and the structure of the program are described. The simulation was used to model the flight behavior of a new technology blimp, the Airship Industries Skyship 500, for which flight test data were available. Simulation predictions follow the same trends indicated by the flight test data. The computer simulation performed well in a wide variety of maneuvers.
