An adjustable pitch aircraft propeller has peripherally spaced composite blades each including an elongated core of expanded rigid foam material extending from a metal base member having a reduced neck portion and an outwardly projecting flange portion. A casing or skin of plastic resin impregnated fabric material surrounds the core of each blade and extends inwardly along the neck portion and also has a flange portion overlying the flange portion of the base member. The skin material overlying the neck portion of the base member is retained by a filament winding impregnated with plastic resin, and the blade is coupled to the propeller hub by an annular lip portion which projects inwardly and overlies the flange portion of the skin material. The foam core of each propeller blade has longitudinally extending slots, and strips of resin impregnated fabric material extend through the slots to form corresponding webs which connect the skin material forming opposite side of the propeller blade.

Power is mechanically transmitted from a tethered airship carrying wind turbines to electrical generators on the ground at the anchor point of the tether, by the use of endless power-transmission cables bridging between drive sheaves at the turbine wheels and driven sheaves at the generators. Tether adjustments, cable tensioning, and wind direction changes are provided for the ground apparatus. A tubular aircraft with recess in the tube wall, carrying bearings on which the rims of the turbine wheels ride, is also claimed.

A power plant for the generation of electricity from the flow of water currents uses turbine wheels within nozzles submerged in the water current, anchored to the bottom of the water course, as for example, the ocean, and self-buoyed to a level well below the water surface. Pairs of counter-rotating turbines are supported by their rims, which bear against friction drive wheels, which in turn drive electrical generators contained in water-tight machine rooms within the wall of the nozzle. A structural design is disclosed, providing for the building of modules of the nozzle ashore, which modules may then be barged to the deep-water site for assembly into the whole power plant.
