Рассматривались варианты конструкции свободнопоточных быстроходных ортогональных агрегатов (VAWT – по терминологии США), преобразующих энергию течений в условиях, когда габариты турбины много меньше глубины и ширины потока. Установлено, что рассмотренные турбины большой длины наибольшую эффективность могут иметь в вариантах с одной сбалансированной лопастью, когда хорда лопасти примерно равна радиусу турбины и развернута на 3–5 градусов (носок лопасти наружу от трассы). Оптимальная скорость вращения в этом случае примерно в 4 раза выше скорости потока, а при постоянной скорости вращения максимальная мощность на валу турбины достигается при скорости потока, близкой к скорости лопасти. Сбалансированная турбина с двумя лопастями и таким же затенением (хорда лопасти вдвое меньше радиуса) имеет примерно такую же эффективность, но при скорости лопастей в 2,5 раза большей скорости потока на подходе к турбине. Отмечена возможность заметного увеличения эффективности турбин при оптимизации разворота лопастей на трассе и увеличении относительного диаметра турбин (D/L).

 

The paper deals with the variants of the design of free flow high-speed orthogonal aggregates (VAWT-USA terminology) that convert the energy of currents in conditions when the turbine dimensions are much smaller than the depth and width of the flow. It is established that the considered turbines of large length can have the greatest efficiency in variants with one balanced blade when the blade chord is approximately equal to the turbine radius and is deployed by 3-5 degrees (the blade sock outwards from the track). The optimal rotation speed in this case is about 4 times higher than the flow velocity, and when a constant speed of rotation, the maximum power on the turbine shaft is achieved at a flow velocity close to the blade speed. A balanced turbine with two blades and the same solidity (the chord of the blade is half of the radius) has approximately the same efficiency but with the speed of the blades is about 2.5 times higher than the flow velocity on the upstream of the turbine. Moreover, the paper notes the possibility of a noticeable increase in the efficiency of turbines by optimizing the rotation of the blades on the track and increasing the relative diameter of the turbine (D/L >5).
