Abstract: The invention relates to devices for simulating physical phenomena, and more particularly to devices for generating waves suitable for training in water sports, for example water skiing, surfing, etc., in indoor and outdoor pools. The technical result of the invention for which patent protection is sought is to produce a standing wave, the body of which has a lower speed of longitudinal flow travel than in known devices, reaching a minimum in the region of the crest of the wave, which significantly improves its attractiveness to users and causes the resulting wave to more closely resemble a wave formed under natural conditions at sea in an area where the sea or ocean floor rises gradually toward the shore, while at the same time making it possible to adjust the parameters of the wave in order to achieve optimal characteristics for each specific case (for example, specific wave parameters for sportsmen and women of different levels, novices, children, adolescents, etc.). The present device for generating an artificial wave comprises a first channel, a second channel with a constant cross section, and a turbine-driven water pump that connects the first and second channels via adapters which adjoin the inlet of the first channel and the outlet of the second channel to the outlet and inlet of the turbine-driven pump respectively, wherein the first channel has a curved outlet portion and the outlet of the first channel is adjoined to the inlet of a convergent nozzle, said inlet being downwardly inclined in a direction away from the outlet of the first channel, and the interior space of the nozzle being delimited by an upper adjustable plane and a lower plane adjoined at a convex angle to a first edge of a first bottom plane that is downwardly inclined in a direction away from the nozzle, a second edge of said first bottom plane smoothly adjoining a first edge of a concave bottom surface, a second edge of which is hingedly adjoined to a first edge of a deflector, transitioning into a bottom plane at a right angle, while a bottom plane of the deflector transitions into a niche situated below the deflector and containing a hydraulic cylinder capable of controlling a change in the angle of inclination of the plane of the deflector, a second side of the niche below the deflector adjoining a first side of a second bottom plane, a second edge of which terminates abruptly in a water collector, the outlet of which adjoins the inlet of the second channel, wherein the space of the water collector is delimited by a lower flat wall, the lower edge of which smoothly adjoins the lower edge of the second channel, wherein the device has an open space that is delimited at one end by the upper plane of the nozzle and at the other end by a second edge of a horizontal wall of the water collector, and the first and second channels, the nozzle, the water collector and also the open space are delimited at the sides by two substantially parallel vertical walls, and the device is provided with a protective perforated bottom which is arranged with a downward incline from the water collector toward the deflector and is fastened to the second bottom plane, to a vertical wall of the water collector and also to the aforementioned vertical walls.
