VERTICAL AXIS WIND MILL WITH POPPING UP DRAG DOOR PANS AND WIND PRESSURE RELEASE SYSTEM

摘要

It is a vertical axis wind mill with sets of popping up drag door pans (2) attached to the lateral side of the central axis (1). Popping up drag doors (3) are pivotally attached to the pans (2). The opposite pans (2) have doors (3) openable towards opposite directions. The popping up drag doors (3) are aerodynamically shaped. When the wind lashes, one pan (2) with closed drag doors (3) is pushed and at the same time the drag doors (3) of the opposite pan [2) opens towards opposite direction and allows the wind to pass other side of the pan (2). Thus two opposite pans (2) create the imbalance of forces and the central axis (1) is rotated. The aerodynamically shaped drag doors (3) also create a life force which also exert force to the pans (2) in the same direction. Thus the central axis (1) gets the pushing force of the wind and lift force generated by the aerodynamic shaped drag doors (3). The rotation of the central axis (1) is converted in to mechanical force and then into electrical force using and an alternator. The doors [12) are pushed by the excess wind and let the excess wind to pass without excreting force on the pans (2).
