The device modifies the reciprocal position of the points where the thrust and reaction are exerted as a function of the "element-support" angle, equilibrium being established so that the orthogonal component along a predetermined direction is a maximum. The technical fields are those of propulsion, of lift, of generators. According to one embodiment, the support 4-23 is presented as a compact crankshaft comprising journals centred at A and B. The median line M of the element 24 is constrained to remain on A by an internal slide 21-37, and its point C to remain at an equal distance from B by the "rod 18". The reaction is exerted on P, the projection of A on BC, which moves, when the flow varies, so that the resultant equilibrium constantly determines a maximum component along BA. <IMAGE>
