Usage: in the energy sector, namely the design of the turbine, allowing you to extend its functionality use without disturbing ecological purity, to make mobile and increase efficiency. The inventive turbine includes: a sealed cylinder 4 on the axis 6 with fairings 5 and the bearings 7; cylinder 1 odnoperogo profile with coffered holder 8 that allows you to submerge to a predetermined depth, to create weightlessness, to adjust the weight of the turbine. Between the cylinders 1 and 4 are screw blade 8, forming a narrowed cross-section at the exit, turn jet ninety degrees, which allowed to increase the speed of rotation of the turbine. 1 Il.

The invention relates to energy, namely the construction of the turbines.

Known turbine where the energy of the jet, getting on the turbine blades, depending on the number of passes of the jet per unit time, gives a certain power on the shaft.

The main disadvantage of the existing turbines is that the conventional scheme of installation of blades on the impeller does not give the possibility of increasing the coefficient of performance (COP) but due to the size, the expansion of the functionality used in conjunction with "Gidroenergostroitel SOS" 93053462/29/053366/ from 29.11.1993, Pen Century. And.

The invention consists in increasing the number of jet passing per unit time through the auger blades due to the constructive solution of the problem.

To achieve the desired technical effect the design of the turbine screw on the drawing represents:

the cylinder 1, odnoperogo profile with coffered holder 2, a filling and discharge openings 3;

the sealed cylinder 4, of smaller diameter, with the fairings and 5 axis 6 and bearings 7.

The sealed cylinder 4 is rigidly mounted in the Central part of the cylinder 1 through the installed between the screw blades 8, which form channels for the oncoming jet.

For turbine operation in a submerged mode produced the loading of caisson holder 2 by the liquid immersion objective at a predetermined depth, the creation of weightlessness and regulation of calculated mass for removal of the maximum power.

The rolling stream, falling between the cylinder 1 and the fairing 5 sealed cylinder 4, through the primary channel narrowing increases its speed, passes utoria form a narrowed cross-section at the exit rotated ninety degrees, the stream velocity increases again, the turbine speed increases, and the rotation of the jet ninety degrees allows you to keep the law of continuity of the jet (Bernoulli) in laminar flow.

Turbine comprising an impeller with blades mounted on the axis of the bearing, characterized in that the screw blades are mounted between the airtight cylinder on axis with the fairings and the cylinder odnoperogo profile with coffered ferrule, forming a narrowed cross-section with the rotation of the jet on the 90o.
