Abstract: An article of manufacture includes a rotor blade configured for use with a turbomachine. The blade is configured for attachment to a rotor wheel. The blade is configured to substantially reduce the possibility of attachment with an undesired rotor wheel by modification of at least one characteristic of the blade, so that the modification of the characteristic is matched by a complementary characteristic of the rotor wheel. The characteristic of the blade is, neck width, platform length, platform angle, platform height, tang height, or circumferential width. The blade and the wheel comprise a first stage of the turbomachine. The undesired rotor wheel is in a second stage of the turbomachine, where the first stage is different from the second stage. The complementary characteristic of the wheel is, slot opening width, platform opening depth, slot neck width, slot neck angle, slot tang depth, or slot tang width.

Abstract translation: 制造品包括被配置为与涡轮机一起使用的转子叶片。 叶片被构造成附接到转子轮。 叶片被构造成通过修改叶片的至少一个特性来大大降低与不需要的转子轮的连接的可能性，使得特性的修改由转子轮的互补特性来匹配。 刀片的特点是颈部宽度，平台长度，平台角度，平台高度，刀柄高度或圆周宽度。 叶片和轮子包括涡轮机的第一级。 不期望的转子轮处于涡轮机的第二阶段，其中第一级与第二级不同。 车轮的互补特征是槽开口宽度，平台开口深度，槽颈宽度，槽颈角度，槽口深度或槽口宽度。
