Сформулированы предложения, повышающие эффективность турбин. Отмечено, что наиболее эффективными в безграничном потоке могут быть многоярусные турбины с одной или двумя фиксированными  лопастями в каждом ярусе, а также турбины с одной спиральной лопастью. Приведены результаты расчетов и лабораторных испытаний по оптимизации турбин и новые предложения по использованию автоматизированных закрылков на лопастях.</p></abstract><trans-abstract xml:lang="en"><p>The paper discusses the features of flows inside orthogonal turbines that determine their low efficiency. Proposals are formulated that increase the efficiency of turbines. It is noted that multilevel turbines with one or two fixed blades in each tier, as well as turbines with one spiral blade, are the most effective in unlimited flow. The paper suggests the results of calculations and laboratory tests for optimizing turbines and new proposals for the use of automated flaps on the blades.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>малая гидроэнергетика</kwd><kwd>ортогональная турбина</kwd><kwd>безграничный поток</kwd><kwd>многоярусная турбина</kwd><kwd>лопасть</kwd><kwd>эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small hydropower</kwd><kwd>orthogonal turbine</kwd><kwd>unlimited flow</kwd><kwd>multi-tiered turbine</kwd><kwd>blade</kwd><kwd>efficiency</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Patent USA 8007235 B1, 2011, Int.Cl.
