Abstract
A method and apparatus for controlling the flight direction of a blimp. The blimp includes an elongate fuselage for containing a lighter-than-air gas, a movable rudder located toward a tail end of the fuselage, and at least one propeller mounted on a side of the fuselage. The propeller is attached to the blimp by a connection that provides two axes of movement. The propeller connection can be rotated or pivoted (1) about a first axis which is a horizontal axis that is perpendicular to a direction of the longitudinal axis of the elongate fuselage, and/or (2) about a second axis which is a vertical axis that is perpendicular to the direction of the longitudinal axis of the fuselage.
