POWER UNIT NOZZLE ASSEMBLY

摘要

wind-power engineering; windmill-electric generating plants. SUBSTANCE: wind assembly has main and additional channels carrying working medium; novelty is that main channel is made in the form of contracting shell whose preferred ratio of inlet to outlet sectional areas is from 20:1 to 25: 1 and that additional channels in the form of contracting shells embracing main channel in coaxial manner are provided on sides of the latter; edge of main-channel outlet is behind respective edge of additional channel by 3-5 diameters of circle whose area is equivalent to that of main channel outlet; in addition, area of inner shell outlet amounts to 0.33-0.67 of that of outer shell outlet sectional area. EFFECT: enhances utilization of effective area of windwheel blades; increased amount of working medium interacting with windwheel. 3 cl, 2 dwg
