The test Reynolds number based on the incoming flow and the blade chord was 100000. The measured results were analyzed in conjunction with the flow fields mapped by using five hole probe.
并结合以前通过五孔针测量取得的流场进行了分析, 得出了该叶栅中紊流参数的变化规律。
Other causes include the out - of - tolerance of blade chord width between adjacent blades, the undersize contact area of serrated working side and the local wearing of non - working side.
而相邻原机件叶片弦宽尺寸超差,锯齿形工作接触面积小,以及非工作面局部碰磨,是引发故障的次要因素。
The influences of re based on the blade chord length and coolant-gas flux ratio are tested, and comparison is made between the effect of the converging-expanding hole rows and cylindrical hole rows.
研究了基于叶片弦长的主流雷诺数和二次流-主流流量比对冷却效率的影响,并与叶片上圆柱形孔排的气膜冷却效率分布进行了对比。
Experimental investigation of the turbine blade local heat transfer characteristics at the inner side of the mid-chord region near film holes was conducted, with and without impingement cooling.
对叶片弦中区内部有、无冲击射流的气膜出流冷却方式中,冷气侧气膜孔局部换热特性进行了实验研究。
The Z-9B variant features a modified 11-blade Fenestron faired-in tail rotor with wider-chord, all-composite blades instead of 13 all-metal blades as in as 365n1.
Z - 9b型特点是一个改进11浆叶涵道尾桨,减阻内置螺旋浆采用宽弦、全-复合浆叶而不是像在AS 365n1型中的13片全-金属浆叶。
Like the Z-9B, the Z-9C also features a modified 11-blade Fenestron faired-in tail rotor with wider-chord, all-composite blades instead of 13 all-metal blades as in as 365n1.
如同Z - 9b, Z - 9c也具有的特征是一个改进11浆叶涵道减阻内置尾螺旋浆,采用宽弦全复合浆叶而不是像AD 365n1型一样的13片全-金属浆叶。
Like the Z-9B, the Z-9C also features a modified 11-blade Fenestron faired-in tail rotor with wider-chord, all-composite blades instead of 13 all-metal blades as in as 365n1.
