Zusammenfassung: | The Variable Foil Machine harnesses fluid flow energy and propels fluids. A flexible foil (120) with reversible camber is secured to leading draft member (150) on leading support (122) and to trailing draft member (130). The trailing draft member (130) is secured to trailing guide (132), movable on trailing support (136). Apparatus can be installed on the ground or a craft via pivoting carrier (138), for alignment with fluid flow. In one embodiment, trailing draft member (130) reciprocates between support members 136l and 136r, upon oscillation of the foil (120). In other embodiments, a reciprocation amplitude offset between leading draft member (150) and trailing draft member (130) promotes cyclic translation of the foil (120) and linkage thereto. An energy converter (142) may be cooperatively coupled to produce energy or perform work. Integration of foil oscillations into rotary movement via a crank arm (48) is also embodied. |
