摘要:
An airfoil for a turbine engine includes pressure and suction sides that extend in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip. The airfoil has a relationship between a total chord length and a span position and corresponds to a curve that has an increasing total chord length from the 0% span position to a first peak. The first peak occurs in the range of 45-65% span position, and the curve either remains generally constant or has a decreasing total chord length from the first peak to the 100% span position. The total chord length is at the 0% span position in the range of 8.2-10.5 inches (20.8-26.7 cm).
摘要(中):
用于涡轮发动机的翼型包括压力和吸力侧,其在径向方向上从内部流动路径位置处的0%跨度位置延伸到翼型末端处的100%跨度位置。 翼型具有总弦长和跨度位置之间的关系,并且对应于从0%跨度位置到第一峰具有增加的总弦长的曲线。 第一个峰出现在45-65%跨度位置的范围内,并且该曲线或者保持一般恒定或具有从第一峰到100%跨度位置的总弦长减小。 总和弦长度在8.2-10.5英寸(20.8-26.7厘米)范围内的0%跨度位置。
