A channel of a series-type magnetohydrodynamic generator comprises a central section with sectionalized electrodes, the ends of the central section adjoining respective transition sections including sectionalized electrodes. Adjacent the free end of each transition section is an end section made as a continuous load electrode. There is a switching element between each pair of the electrodes of the transition sections and between the 'outermost electrode of the transition section--load electrode'. Connected in parallel with the switching elements are relay and a respective type limit voltage switching elements. Sensitive elements of the same type are inserted between the outermost adjoining sectionalized electrodes of the central and the transition sections.

Channel of series-type magnetohydrodynamic generator

A duct for a magnetohydrodynamic generator having diagonally conductive walls formed with extended modules of a suitable electrically conductive material, which are electrically insulated from one another and oriented so that each module has sections inclined at an angle with respect to the longitudinal axis of the duct, said angle being varied within .pi./2.gtoreq..alpha..sub.max .gtoreq..alpha..gtoreq..alpha..sub.min .gtoreq.0. The extended modules are C-shaped and oppositely disposed in an alternating manner so that the number of electrical breaks per unit length of the duct along its axis on the walls formed with sections of the modules inclined at the angle .alpha..sub.max with respect to the duct axis exceeds twice the number of electrical breaks along the duct axis on the walls formed with sections of the modules inclined at the angle .alpha..sub.min with respect to the duct axis.

Duct for magnetohydrodynamic generator

A magnetohydrodynamic device having a duct for a conducting gas to flow at an angle with the direction of the magnetic field induction vector. The duct is situated in the magnetic system and is provided with a plurality of electrodes adapted to interact electrically with the gas, whereas the cross-sectional shape of the duct working space is bounded by a closed contour formed by a curve inscribed into a rectangle having its sides a.gtoreq.b, while the minimum radius R of curvature of said curve is related to the distance x from the entry to the duct for the conducting gas to flow, to the cross-section under consideration by the following formula: ##EQU1## where P.sub.o and S.sub.o stand, respectively, for the perimeter and cross-sectional area of the duct 1 at the entry thereof, and 0.5.ltoreq..alpha..ltoreq.1.
