Abstract
Open and closed cycle lift force turbines are provided. Illustratively, the open cycle lift force turbine operates in an open cycle environment without heat and/or pressure, utilizing asymmetric pressure distribution on lift turbine blades mainly to generate thrust with the normal component of this lift force, while using the tangential component of this lift force to drive a bypass fan providing additional thrust and to drive accessories, provide control to the fluid velocity, and/or provide motivation of the fluid's flow. The open cycle lift force turbine may be utilized to generate continuous thrust, heat and/or electricity for powering vehicles in any atmosphere. The closed cycle lift force turbine may be utilized to generate continuous thrust, heat and/or electricity for powering vehicles at any speed in any atmosphere or lack thereof.
