DEVICE WHICH PRODUCES A CARRTING FORCE WHEN PLACED IN A MOVING FLUID

摘要

This invention is an energy-efficient lift device in air flow for a ship. This lift device moves along a first direction in order to produce carrying force in the second direction perpendicular to the first direction. This device includes an elongated body which has symmetric round section profile in the first direction. The body sucks in fluids in an intake zone located on the first side of the profile in the trailing edge. The carrying force is supposed to be produced at the first side. A flap is projected on the opposite side of the trailing edge. The profile is divided into a leading edge in the form of pseudo-elliptical and a trailing edge in the form of semi-circle.
