FIELD: wind power engineering; wind motors of various purpose and power. SUBSTANCE: lower and upper planes are engageable with part of cylindrical surface of radius "r" determined from the following formula: $$$, where r is radius of cylindrical surface, m; 2.744 is squared speed coefficient; V is velocity of air particles incoming on blade, m/s; $$$ is acceleration of air particles, m/sq.s. EFFECT: enhanced efficiency. |
