Vane of turbine
专利汇可以提供Vane of turbine专利检索，专利查询，专利分析的服务。并且PURPOSE: To put aside an impulse wave toward the negative pressure side and enhance the vane efficiency as well as stabilize the function by providing a bend at the vane surface side, where a speed reduction zone exists, or by setting the curvature on the negative pressure side, where a speed reduction zone exists, at the curvature on the prssure side of the counter situated vane surface.
CONSTITUTION: In a transsonic vane having speed reduction zone, either a band B is furnished at the vane surface side (negative pressure surface), where a speed reduction zone exists, or the curvature R
s on the negative pressure side, where a speed reduction zone exsists, is set larger than the curvature R
p on the pressure side of the opposite vane surface. Consequently, the range with generation of impulse wave, S4-S3, does not include speed reduction zone W and the pressure difference between before and after an impulse wave is small in this range, so that no large changing motive is applied to the vane body P. Thus failue of the vane body P can be prevented and stable function is assured under a wide extent of transsonic flow.
