Static and Dynamic Simulation of Tethered Airship

Both static and dynamic models of a tethered airship are developed,in which the cable is divided into several segments of nodes and each segment is considered to be a lumped mass spring.The result of simulation of the airship in static state shows that the internal tension increases along the cable from ground to the junction of airship;In a certain extents,the altitude of airship increases and the horizontal shift decreases as increasing of the angle of attack,however the internal tension also significantly increases;weight of the cable has a great effect on the performance of the tethered airship system.As wind speed increases,the altitude of airship decreases,the horizontal shift increases,while the tension increases.In changing wind conditions,the internal tension varies a little.
