Description
В известных способах регулировани оборотов небольших быстроходных ветровых колес (z 3-r6) нутем их вывода из-под ветра поворотом относительно вертикальной оси головки не обеспечнВаетс достаточна динамическа устойчивость системы при соответствуюш,ей закономьрности изменени поворотного момента ветрового колеса.In the known methods of controlling the revolutions of small high-speed wind wheels (z 3-r6), by removing them from the wind by rotating the head about the vertical axis of the head, the dynamic stability of the system is not sufficient, if the turning wheel of the wind wheel changes accordingly.
В предлагаемом способе этот недостаток устранен тем, что на лобовой стороне крыльев ветрового колеса помещают жесткие открылки, концентрично расположенные относительно оси вращени колеса.In the proposed method, this disadvantage is eliminated by the fact that on the front side of the wings of the wind wheel, there are rigid wing panels concentrically located relative to the axis of rotation of the wheel.
На фиг. 1 схематически изображено осуществление способа; на фиг. 2 - графические характеристики коэффициентов касательных сил.FIG. 1 schematically shows the implementation of the method; in fig. 2 - graphic characteristics of the coefficients of tangential forces.
Предлагаемый способ изменени формы характеристик поворотных моментов ветроколеса 1 предусматривает установку на его лопаст х 2 неподвижных односторонних открылков 3. При расположении открылков со стороны набегающего потока концентрично оси вращени ветроколеса они практически не вли ют -на мощностные характеристики ветроколеса при его нормальном обтекании. В то же врем при косой обдувке ветроколеса присутствие открылков существенно сказываетс на моменте аэродинамических сил, поворачивающем ветроколесо около оси головки ветродвигател . Это подтверждаетс фиг. 2, на которой даны характеристики коэффициентов касательных сил т / (г) и центра парусности Z f (z) быстроходного ветроколеса при различных углах его косой обдувки Yi, полученные при испытани х модели в аэродинамической трубе. Как видим, при наличии открылков не только увеличиваютс касательные силы, но и наблюдаетс смещение центра парусности к задней кромке ветроколеса, благодар чему момент от сил лобово-го давлени становитс положительным при любых углах его косой обдувки.The proposed method of changing the shape of the characteristics of the turning points of the windwheel 1 provides for the installation on its blades x 2 fixed one-sided wings 3. With the location of the wings from the side of the incident flow concentric with the axis of rotation of the wind-wheel, they practically do not affect the power characteristics of the wind-wheel during its normal flow. At the same time, in the case of oblique blowing of the wind-wheel, the presence of the wings significantly affects the moment of aerodynamic forces turning the wind-wheel near the axis of the head of the wind turbine. This is confirmed by FIG. 2, which gives the characteristics of the coefficients of the tangential forces t / (g) and the center of sail Z f (z) of the high-speed propeller at different angles of its oblique blowing Yi, obtained from testing the model in a wind tunnel. As you can see, in the presence of an velcque, not only the tangential forces increase, but also the displacement of the center of the windage to the rear edge of the windwheel is observed, due to which the moment from the frontal pressure forces becomes positive at any angles of its oblique blowing.
