IMPROVEMENTS IN A HIGH SUSTAINING FORCE DEVICE TO USE FLUIDS ENERGY IN A MOVEMENT ESPECIALLY FOR THE WIND PROPULSION OF SHIPS.

摘要

1. A device adapted to be placed in a fluid in movement in a first direction (vector V) in order to produce a carrying force (vector P) in a second direction transversely of the first direction, the device comprising an elongate body (10) having a rounded profile in cross-section in the first direction, means (12) for intaking the fluid into the body in an intake zone (54) situated at least on the trailing edge of the profile on a first side (10a) on which the said carrying force is to be produced and a flap (14a, 14'a) projecting from the body (10) on the trailing edge of the profile on the opposite side (10d) to the second direction, characterised in that the said profile has an elongate leading edge in accordance with a pseudo-elliptical law and a trailing edge in accordance with a semi-circular law, said profile being symmetrical with respect to a single axis of symmetry (XX') which together with the first direction (vector V) defines an angle of incidence (i) directed in the second direction, the maximum thickness (e) of the profile being between 50% and 100% of its length (1) in the direction defined by its axis of symmetry.
