<p>The invention relates to an ecological thrusting device enabling optimum thrust independent from the outside environment. It consists of a special Francis turbine (1) from which the fluid is axially ejected at the outlet of the vane (1'), at a relative speed W2t, and is collected in a defined free space of a straight radial pump (2). Under the action of the centrifugal force, the limit of the current lines forms a fixed virtual barrier Yt, thus preventing the centrifuged fluid from reaching the bottom of the pump in the free space area MNBCPQ, thereby eliminating the antagonistic force exerted on said zone. As a result, the thrusting force exerted on the turbine by the fluid remains intact. As the fluid leaves the pump, it is axially reinjected at a relative speed W2p into a tank (4) for resupplying the turbine. There is therefore an energy exchange between the pumps and the turbine that form a closed circuit, the entire system being driven by a motor (10). It is shown that the thrust force P = (1/2) pp?2 r4; p being the density of the centrifuged fluid in en Kg/m3; ? being the angular speed of the turbine in rad/s; and r its radius in metres and P in Newtons. The calculation shows that the amount of thrust generated is very high; said thruster can be used to generate mechanical energy anywhere in space, and especially to drive the most highly efficient flying machines.</p> |
