Abstract:
1. A wing engine comprising two pairs of vanes, each pair of vanes being attached to a respective horizontal shaft, each pair of vanes being diametrically opposed on the respective shaft, each horizontal shaft being mounted immediately adjacent to each other on a common central rotor base which is operative to rotate about a vertical axis, each horizontal shaft being mounted on the rotor base such that each horizontal shaft can pivot through 90° about the respective shaft axis, the pivotal movement of each shaft being governed by a cam such that, in use, one vane of each pair of vanes is at 90° to the other vane in that pair of vanes, wherein each horizontal shaft is mounted on a respective pair of bearings, the bearings being mounted on the rotor base, the bearings in each pair being relatively spaced apart from each other such that each horizontal shaft is supported at two spaced apart positions on the rotor base.
