Abstract

FIELD: machine building.SUBSTANCE: invention relates to marine jet propulsors. Magnetohydrodynamic program-controlled stepper motor for marine microruncules is made in the form of two cylindrical tubes nested into each other with orthogonally arranged electromagnets. Electromagnets on outer tube are arranged in pairs with electromagnets on inner pipe to form magnetic field. At step-by-step variation of current in electromagnets the fluid flow rate will vary depending on the selected direction of motion. At that, since mass of pushed liquid will exceed mass of the engine itself, water will remain fixed, and engine itself will acquire rotary-translational motion with possibility of program-controlled maneuvering in any direction.EFFECT: technical result consists in the fact that the motor together with the microdron acquires rotary-translational motion.1 cl, 1 dwg

Description

The invention relates to propulsion and can be used on ships.

A disadvantage of the known devices [1-3] is the movement of the water flow, which leads to the appearance of parasitic vortex flows and energy losses.

The aim of the invention is to increase the power and controllability of magnetohydrodynamic software-controlled stepper motor for marine microdrones.

The technical result is the effect of a magnetic field on the anions and cations of sea water in such a way that the engine itself, together with the microdronome, acquires a rotational-translational motion, while the sea water itself will remain almost stationary.

This technical result is achieved by the fact that the magnetohydrodynamic software-controlled stepping motor for marine microdrones is made in the form of two cylindrical tubes nested with each other with electromagnets placed orthogonally and with step-by-step current changes in the electromagnets the flow rate of the fluid will vary, and as the mass of the ejected fluid will exceed the mass of the engine itself, the water will remain stationary, and the engine itself Spruce will acquire rotational motion with the possibility of program-controlled maneuvering in any direction.

FIG. 1 shows a diagram of a magnetohydrodynamic software-controlled stepper motor for marine microdrones. The metal cylindrical electrode 1 is connected to the positive pole of the power source, and the metal cylindrical electrode 2 is connected to the negative pole of the power source. Under the action of these potentials, positive anions in seawater will move in radial directions from the positive electrode to the negative one. Negative cations will move towards them. The step electromagnets 3 on the outer tube are arranged in pairs with the same electromagnets 4 on the inner tube to form a magnetic field, which with the help of the Lorentz force will create mutual repulsion of the outer and inner tubes relative to anions and cations. Programmed switching of electromagnets will lead to the possibility of creating a circular displacement of an ejection pulse. If both pipes are fixed, then in this case there is a vortex motion of the fluid with its simultaneous ejection from the space between the outer and the inner tube. If the pipes are not fixed and the engine weight is less than the mass of the water pushed out, then the water will remain almost stationary, and the engine will acquire a rotational-translational motion. The rotation speed control can be programmed by changing the speed of the step-by-step switching of electromagnets, and by changing the potential on the electrodes and the current in the stepping electromagnets, you can change the speed of the translational motion. It can be programmatically set as alternate single switching on of a pair of orthogonal electromagnets with all other electromagnets off, and to increase the number of included orthogonal electromagnet pairs to the value at which all electromagnets are turned on and in turn in a circle each pair turns off sequentially. If, when switching by software, the current in a pair of orthogonal electromagnets is changed in such a way that the current in any sector is greater than in the opposite sector, then in this case you can control not only the speed of rotation and translational motion, but also change the motion vector arbitrarily .

Since only the microdron itself with an engine in the form of a cylindrical tube participates in the movement, and the aquatic environment remains practically stationary, this will allow for virtually silent movement, and the low noise factor is of great importance for military use and environmental safety.

Magnetohydrodynamic software-controlled stepper motor for marine microdrones is able to work at any depth and under any climatic conditions with high energy efficiency and controllability.
