摘要： The present invention is intended to provide a cooled blade of a small gas turbine engine which can enhance cooling performance without increasing an amount of cooling air although it is in a simple configuration. A cooled turbine blade is provided with a cooling passageway 12 formed inside thereof, making the cooling air flow therein; film-cooling holes 13 formed, penetrating from an inner wall surface 111 to an external wall surface 112 and forming a cooling film; and an impingement cooling member 2 which has a multiple number of small holes 21 ejecting the cooling air. It is characterized by that a gap t made by the inner wall surface 111 and the impingement cooling member 2 has a sealing portion 14 mounted thereon which divides the gap in a blade chord direction.

摘要： In a centrifugal compressing apparatus, a height of a blade of an impeller is made to decrease gradually from a front edge thereof to a rear edge thereof, and a rate of change of the height of the blade is relatively large near the rear edge. The height of the blade can be made large at the rear edge side under the design restriction that an exit width of the rear edge of the blade is set to a predetermined design value. The ratio of the width of the clearance and the height of the blade is thereby made relatively large. As a result, the ratio of a flow path area occupied by a clearance flow to a flow path area occupied by a main flow is reduced. Since the pressure loss is thus made small, a drop in the efficiency can be prevented.
摘要翻译：在离心压缩装置中，叶轮的叶片的高度从其前边缘到其后边缘逐渐减小，并且叶片的高度的变化率在后边缘附近相对较大。在设计限制下叶片的后缘的出口宽度被设定为预定设计值的情况下，可以在后边缘侧使叶片的高度大。因此，间隙的宽度与叶片的高度的比例相对较大。结果，由主流所占据的间隙流量所占的流路面积与流路面积的比例降低。由于压力损失小，所以可以防止效率下降。
