7.7. Conclusions.

Rate it

Good results were obtained in the study device performance in an air flow (speed from 0 to 180 m / sec) (a further increase in air flow rate was limited by the aerodynamic features of the stand) can rely on efficient use of this device not only as a generator for wind turbines, but in different modes:
- The generator, when the working environment - water;
- "Motor-generator" in the future means of transport;
- "Mover" ("prop") for maritime and river vessels.

The obtained results of experimental aerodynamic research was a complete surprise and did not meet the basic laws of physics. It turned out that the working chamber located in the work items in the interaction with the air flow not only started to oscillate stably in the air flow, drawing power, as expected, due to the kinetic energy of the flow of air, but the kinetic energy of the flow of air at the same time even increased. Moreover, this increase in kinetic energy of air flow was observed even at partial renting of useful work from the shaft of the generator, installed on the shaft of a rotary cranks work item.

It can be assumed that the most likely explanation of the results of aerodynamic test data submitted on the charts 10 and 11, are errors in the method of measurement. Perhaps filling the working chamber of the work items was too dense, air flow rate may have been too high (a large sum of mechanical damping due to imperfect design does not allow testing at low flow rates), may be evidence obtained by means of static pressure sensors are associated with an increase in air flow rate is near the walls of the working chamber (oscillating working elements made it impossible to measure the velocity sensors of total pressure).

However, the evidence obtained consisted of three readings averaged static pressure sensors in each section, and the variations in the levels of fluid in the manometric tubes were practically negligible. In addition, the study of oscillations of 6, 4 or 2 work items of static pressure sensors located along the stream at a considerable distance from the plane of oscillation of work items, but the general nature of graphical dependencies are not affected.
And another very interesting pattern: the number of workers in any part of any turbulent flow at the inlet to the working set becomes laminar after the first work item at any flow rates (in the future, this was confirmed when testing the sample and following the installation of water and air flows on " natural "rates of air or water flow).

Of course, the first installation was made imperfect execution of transfer mechanisms and their connection to each other and were far from perfect, the working air flow rate when tested under real conditions is practically not observed, the flutter of a single item was not obtained, but repeated retesting stubbornly came from those same results. 

Given that the results of the experiments were extremely interesting, they were not taken from some publications, but were obtained in person during aerodynamic tests and these tests I could trust completely, I decided to continue these studies.
