技术领域
本申请涉及一种用于空气循环机中的喷嘴。
已知空气循环机且其通常包括一个或多个涡轮，所述涡轮接收压缩空气源且被驱动来旋转。接着，涡轮旋转压缩机转子。空气由空气循环机调节且被移动用于飞机机舱空气调节和温度控制***。
涡轮通常具有喷嘴，其控制涡轮转子上游的空气流量。
发明概要
一种用于空气循环机中的喷嘴具有板。多个叶片背离板延伸一个高度。宽度被界定为两个相邻叶片之间的最近距离。所述高度与所述宽度的比介于3.253与3.800之间。还公开了一种空气循环机及维修方法。
从下文附图和详述可最好地理解这些和其它特征。
附图简述
图1示出空气循环机。
图2A示出与第二级涡轮转子相关联的涡轮喷嘴。
图2B是沿着图2A的线B-B的截面图。
图2C是喷嘴的一部分的放大图。
具体实施方式
图1中图示了空气循环机20，其具有由轴24驱动的风扇22。如已知，压缩机转子3528在入口126处从压缩空气源接收压缩空气且被驱动成旋转来进一步压缩空气。空气向下游流入第一级涡轮入口26中，其驱动第一涡轮转子级28。接着空气流到第二涡轮转子级32的入口30且接着到达出口34。空气从出口34流出用于飞机机舱且作为机舱空气调节和温度控制***的部分。
涡轮喷嘴36与第二级涡轮转子相关联且用来将气流从入口导引到涡轮转子32。
第一级护罩和喷嘴127包括延伸到转子28下游的位置的护罩128和在转子28上游的喷嘴130。
图2A示出与第二级涡轮转子32相关联的喷嘴36。如图所示，喷嘴36具有板60，其具有背离板60延伸的多个周向间隔的叶片62。内孔70被图示且以中心轴C处于中心。
图2B是沿着图2A的线B-B的截面图。如图所示，喷嘴36具有背离板60在轴向方向上延伸距离d1的叶片62。
如图2C中所示，距离d2可在叶片62的相邻叶片之间界定且是所述两个叶片之间的最短距离。这个距离已知为通道宽度。
如图2A至图2C中所示，在这个实施方案中存在17个喷嘴叶片。在一个实施方案中，d1距离已知为通道高度且是1.11英寸(2.8194厘米)。喷嘴宽度d2是.316英寸(.80264厘米)。宽度d2是两个相邻叶片62之间的最近距离，其是与叶片62的翼型平行或相切所测。17个叶片之间的总流量面积是5.963平方英寸(38.47厘米)。
在实施方案中，通道高度d1与通道宽度d2的比介于3.253与3.800之间。总喷嘴流量面积介于5.508与6.434之间。
喷嘴36具有碳化钨防腐涂层。喷嘴36由铝基体形成且接着具有碳化钨防腐涂层。优选地，利用连续燃烧来提供高速氧燃料涂层技术。
一种维修空气循环机20的方法包括以下步骤：从第二级涡轮转子32邻近处的位置移除喷嘴36。接着更换的喷嘴36安装在转子32邻近处。
题目是Turbine Nozzle and Shroud且与本文同一日期提交的共同未决申请案序列号13/869045、代理案号第PA25460US号；第67010-486US1号中公开和要求了喷嘴和护罩127的细节。
虽然已经公开本发明的实施方案，但此项技术的一般工作人员将意识到某些修改可在本公开的范围内。出于这个原因，以上权利要求应被研究来决定本公开的真实范围和内容。
