Method for producing mechanical work

Abstract

Method for producing mechanical work The invention pertains to the field of power engineering and may be applied to convert kinetic and thermal energy of a working medium into mechanical work. The method includes swirling of a pre-compressed working medium, its expansion in an actuating device to produce mechanical work in the form of rotation of the shaft ( 3 ), and discharge of the working medium from the actuating device. The working medium is swirled in the actuating device along a spatial trajectory in the form of a conical helix, the projection of which on a plane positioned at an angle to the axis of rotation is a curve having at least two breakpoints.

1 . A method for producing mechanical work, which includes swirling of a pre-compressed working medium, its expansion in an actuating device to produce mechanical work in the form of rotation of the shaft, and discharge of the working medium from said device which is different that the working medium is swirled in the actuating device along a spatial trajectory in the form of a conical helix, the projection of which on a plane positioned at an angle to the axis of rotation is a curve having at least two breakpoints. 
     
     
         2 . A method according to  claim 1 , in which a segment of said curve is shaped as a hyperbolic spiral. 
     
     
         3 . A method according to  claim 1 , in which the lead of the conical helix in a frontal plane passing through the axis of rotation is made variable. 
     
     
         4 . A method according to  claim 1 , in which the discharge of the working medium from the actuating device is accomplished by at least two jets. 
     
     
         5 . A method according to  claim 4 , in which the working medium is discharged to a closed shell. 
     
     
         6 . A method according to  claim 5 , in which said shell is made in the form of a blade turbine and mounted with a capability of rotating.
