ABSTRACT:
A lighter-than-air aircraft includes a rigid platform having cargo and passenger compartments and gas bags attached to the platform for holding a gas having a density less than air, thus imparting lift to the platform. The bags are arranged in pairs, there being a pair of spaced apart upper bags along the upper surface of the platform and a pair of spaced apart lower bags along the lower surface. While the bags cover portions of the upper and lower surfaces, both surfaces remain exposed along the longitudinal centerline of the platform, and here the platform is provided with vertical ducts and bays. The ducts house motors and propellers which drive air through the ducts and thus impart a vertically directed force to the platform. The bays hold containers which are lowered from and raised into the bays with a crane that moves along tracks extended along the upper surface of the platform. Along the sides of the platform are nacelles which house motors and propellers for providing the thrust to propel the aircraft in flight. The nacelles tilt so that the thrust derived from them may be used to change the elevation of the aircraft. Rudders for controlling the direction of flight are in the regions between the upper gas bags and in the regions between the lower gas bag. The motors in the ducts and nacelles may be electric, with the electrical energy for driving them being derived from a motor-generator set in one of the containers.
