Airship Superpressure Control and Thermodynamic Property during Hovering
As a kind of flexible aircraft,the aerodynamic configuration of airship is maintained by superpressure of internal gas completely.And the pressure difference must be controlled in a safe range.Aiming at these issues,the models of pressure difference and solar radiation are built.Combining with the airship thermodynamic model,pressure control is achieved.A method of direct control is presented.According to the pressure value of atmosphere and the desired pressure difference,the internal pressure of airship that needs to be maintained can be figured out.And the change of internal gas can be obtained accordingly.Aiming at the hovering phase,the models and the control method are simulated.The control results of pressure difference and the thermodynamic properties are obtained,which illustrate the effectiveness of control method.
