Description

用于空气循环机的涡轮喷嘴和护罩
技术背景
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***。
涡轮通常具有喷嘴和护罩，其控制涡轮转子上游和下游的空气流量。
发明概要
一种用于空气循环机中的喷嘴和护罩具有板和护罩，所述护罩相对于板在第一轴向方向上绕着护罩的中心轴弯曲。多个叶片在第二轴向方向上背离板延伸。多个叶片背离板延伸一个高度和界定为两个相邻叶片之间的最近距离的宽度，所述喷嘴高度与所述喷嘴宽度的比介于1.3653与1.7992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示出护罩和喷嘴。
图2B是图2A喷嘴的正视图。
图2C示出细节。
具体实施方式
图1示出空气循环机20。第一级涡轮转子18包括喷嘴和护罩总成21，其调节跨过转子18的通道的空气。护罩部分17远离且超过转子18弯曲。压缩机入口17接收压缩空气源且将其传输跨过压缩机转子。压缩空气流入入口19中，且到达第一级涡轮转子18，且接着到达出口27。出口27与使空气流过第二级涡轮转子24的入口26连通。第二级涡轮转子24将空气传输到出口30。出口30可与飞机机舱连通。如同由涡轮转子18和24驱动，轴32驱动压缩机转子29和风扇转子22。喷嘴和护罩组合50与转子24相关联。
图2A示出喷嘴和护罩组合21。如所示，护罩部分17背离板54相对于中心轴C在第一方向上延伸。与护罩17比较，叶片52示出为在相反方向上从板54延伸。叶片52延伸达背离板54平行于中心轴C所测的距离d1或高度。如图1中清晰可见，护罩延伸到转子18下游，而叶片52在上游。
图2B示出喷嘴和护罩组合21，其具有板54和绕着中心轴C周向间隔的多个叶片52。
图2C示出以最近距离间隔达尺寸d2或宽度的相邻叶片52。d2是与叶片52的机翼的侧边相切或平行所测。
在实施方案中，存在19个周向间隔的叶片52。高度d1是.400英寸(1.016厘米)。宽度d2是.255英寸(647.7厘米)。在d2位置且贯穿跨过全部19个叶片的d1所测的总喷嘴流量面积是1.938平方英寸(12.503平方厘米)。
在实施方案中，d1与d2的比介于1.3653与1.7992之间。总喷嘴流量面积介于1.6802平方英寸至2.2141平方英寸之间(10.840厘米到14.284厘米)。
喷嘴和护罩121具有碳化钨防腐涂层。喷嘴和护罩121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：从第一级涡轮转子18邻近处的位置移除喷嘴和护罩组合21。接着用更换的喷嘴和护罩组合21更换移除的组合。
虽然已经公开本发明的实施方案，但所属技术领域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。
