Creation of Water Engines for Mobile Micro Hydropower

Based on the results of the experiment, the following important conclusions can be drawn for the manufacture of a water engine:- the number of working shafts of the engine should be 4, each shaft should have 3 wheels;- wheel diameter - 40 cm, the distance between wheels on one shaft should be 50 cm;- the distance between the shafts should be 45 cm;- the angle of inclination of the wheel blades located on the first row should be 600, and on the following ones it should be reduced by 5-100;- the diameter of the wheel hubs should be 8÷10 cm;- The thickness of the blades must be at least 1.5 mm.A water engine with overall dimensions of 1800×1100×500 mm, manufactured on the basis of the above conclusions, can provide power at a speed of 1.5 m/s – 2.1 kW, at 2.0 m/s – 4.5 kW, at 2.5 m/s – 8.7 kW, at 3.0 m/s – 15 kW, respectively.
