Abstract
An airship having improved controllability which comprises: an axial fluid pathway penetrating through a body of the airship in an axial direction, at least one radial fluid pathway crossing the axial fluid pathway and penetrating through the body in a radial direction, the axial fluid pathway and the radial fluid pathway forming a ventilating-thrusting tube having a rigid framework construction, propulsion means, thrust generating direction of which is adjustable, arranged in a crossing region of the axial fluid pathway and the radial fluid pathway, and a lift balloon arranged beside the ventilating-thrusting tube in such a manner that a gap is formed between the ventilating-thrusting tube and the lift balloon to allow air to flow through. This arrangement lowers a tendency of yawing due to a transverse wind. The airship has a semi-rigid and semi-flexible construction capable of making up for drawbacks of both rigid type and flexible type.
