FIELD: transportation.
SUBSTANCE: underwater propulsors performance versions, each of which includes the external aerodynamic shell, groups of discharge electrodes pairs, power plant for creating impulse voltages between the discharge electrodes. In the first version, the outer aerodynamic shell of the underwater propulsor is made in the form of biconvex symmetric curved linked spherical, cylindrical or conical surfaces of rotation. In the second version, the outer aerodynamic shell of the underwater propulsor is made with the longitudinal section in the form of the biconvex symmetric lens of the lenticular profile with variable curve. In the third version, the outer aerodynamic shell of the underwater propulsor is made of the truncated diamond-shaped longitudinal section in the form of the curved linked symmetric ruled surfaces.
EFFECT: efficiency improvement of high and ultra high pressure on the underwater propulsor outer aerodynamic shell.
