AIRSHIP POWER TURBINE

摘要

PATENT APPLICATION Title: AIRSHIP POWER TURBINE: A lighter-than-air craft shaped in the form of an elongated tubular nozzle is provided with a converging nozzle section, a vena contracta, and a diverging discharge section. An annular toroidal lighter-than-air secondary nozzle surrounds the discharge end of the first nozzle, is spaced from and supported from the first nozzle with airfoil spokes leaving an annular nozzle space and annular vena contracta therebetween. At the vena contracta of the first nozzle there is provided a pair of counter-rotating turbine wheels each having a shroud-ring rim, said rims being supported on bearings within an annular recess surrounding the vena contracta of the first nozzle. Means are provided for transferring power generated in said turbine wheels by passage of wind therethrough to a pair of endless cables, extending from the craft to the ground. At the ground, the said cables drive sheaves which conduct the power to electrical generators.
