  • Magnetohydrodynamic inertial actuator
    Patent number: 9994337
    Abstract: An inertial actuation magnetohydrodynamic wheel (2) comprising a torus-shaped fluid ring (3) filled with a conductive liquid, at least one effective area (24, 26, 28) for setting the liquid into motion, and at least one magnetohydrodynamic pump (4, 6, 8). The ratio of the set back distance of any magnetic conduction element (24, 26, 28) of the air gap of any electromagnetic pump (4, 6, 8) over the internal size of the fluid ring (3) is greater than or equal to 0.5 and the fluid ring (3) comprises at least two distinct effective areas (24, 26), for setting the conductive liquid into motion, angularly spaced apart by at least 120°.
