CORRECTIVE PROPULSION PLANT WITH ELECTROTHERMAL MICROMOTOR

FIELD: electricity.SUBSTANCE: invention relates to space technology, namely to ammonia corrective propulsion plants with electrothermal micromotors installed on maneuvering small spacecraft. Corrective propulsion plant with electrothermal micromotor, containing the fuel tank with the fuel, electric valve of cylindrical shape on the tank discharge pipeline, filter, the fuel heater in the form of evaporator with a heating element, a pressure control valve, the electrothermal micromotor and connecting piping, in accordance to the invention, the part of the tank discharge pipeline is made in the form of coiled piping, disposed on the outer surface of the cylindrical shell and contacting with it by means of heat-conducting units in the form of, for example, solding connection, at that the electric valve is coaxially installed in the internal shell cavity, at that the outer surface of which through the heat-conducting units in the form of, for example, the thermally conductive paste, contact the inner surface of the cylindrical shell, wherein the inlet pipe of the coiled piping is connected to the tank discharge pipeline, and the outlet - with the filter, coupled to the inlet electric valve fitting, the outlet fitting of which is connected to the inlet fitting of the first independent screw gas duct, configured as a spring on the cylindrical housing of the heating element and contacting with it surfaces of the cylindrical hole in the inner housing of the evaporator, the outlet fitting of which is connected to the inlet fitting of the pressure control valve, which output is connected to the inlet of the second independent screw gas duct, configured as a double-lead thread on the outer surface of the inner evaporator housing, contacting to the inner surface of the main housing, the output fitting of which is connected to the micromotor inlet.EFFECT: increase of the micromotor specific drag impulse, reduction of the fuel stock and the number of inclusions to produce the fuel.7 dwg Изобретение относится к космической технике, а именно к аммиачным корректирующим двигательным установкам с электротермическими микродвигателями, устанавливаемым на меневрирующих малых космических аппаратах.
