A new aerodynamic design system developed by authors for draft fan with enhanced efficiency, suppressed noise, enlarged flux and high load. the new design system features : a twist regulation for vortex control is employed in designing to lessen the secondary flow loss in the blade tip and hub ; the feasibility and high efficiency of this procedure has been verified by the tests of the prototype fan ; a new computer - aided 3d blading is used to optimize the blade ; numerical inverse checking is adopted to enhance accuracy in designing and cut down the period of the designing and production. this design system can make the optimized blade with " forward inclination ", " inclining sweep ", " bending sweep ", to minimize the various secondary flow losses, to expand the steady working range of the fan, and to suppress the aerodynamic noise source
本文通過對一種新型高性能礦用局部通風機的設計、製造及試驗全過程的綜述，展現了新的先進設計體系在民用通風機上的成功運用，其研製特點是： （ 1 ）在葉片氣動設計中為了降低葉根及葉尖區二次流損失，採用可控渦扭向規律設計，樣機實測的高性能驗證了這種方法的可行性和高效性； （ 2 ）在設計方法中採用較精確的數值反驗算，獲取最優設計方案，大大提高設計的準確性和成功率，並縮短了設計試制周期； （ 3 ）在設計過程中發展了計算機輔助三維葉片造型新方法，可以根據設計需要簡便快捷地對葉片進行「前傾」 、 「傾掠」或「彎掠」造型，這些造型對減小各種二次流損失、擴大穩定工況范圍和控制葉輪機氣動噪聲源起到了非常好的作用。 -
