| 摘要: |
| 针对新一代液体火箭发动机层板式喷注器通道流动的设计，通过改变压降、通道长度、流体粘度，试验测量了厚度０．２ｍｍ，０．１ｍｍ，０．０５ｍｍ三种矩形截面层板通道的流量系数，对获得的系列试验数据进行了定性分析，并试验测量了矩形截面直角层板通道的流量系数。 |

| Abstract: |
| n order to design flow passage of platelet injector in a new generation of liquid propellant rocket engine, experimental studies on discharge coefficient of rectangle-cross-section platelet flowpassage with thickness of 0. 2 mm, 0. 1 mm, 0. 05 mm were conducted by varying injection pressure,passage length and liquid viscosity. An qualitative analysis was made on the data obtained by tests.Discharge coefficient of rectangle-cross-section passage with right angle was also measured. |
