涡轮发动机的涡轮环以及涡轮发动机
摘要：
一种涡轮机，特别是直升机的涡轮环，减少了其振动行为。根据本发明，该涡轮环包括基本圆柱形的支撑件(31)，以及形成一个冠部的一个或多个扇区(32)，该冠部被配置成提供气流截面，每个扇区(32)均通过一个固定装置(33a、33b)被紧固到该支撑件(31)上，其中该固定装置(33a)包括一个属于该支撑件(31)并朝该扇区(32)突出的固定部件(35)，以及一个属于该扇区(32)并朝该支撑件(31)突出的固定部件(34)，该支撑件(34)的和该扇区(35)的固定部件被配置成接合以将该扇区(32)紧固到该支撑件(31)上；该环还包括阻尼器装置(50)，该阻尼器装置设置在该固定装置(33a)中，并被径向限制在该扇区的一个部分(34e)与该支撑件的一个部分(31i)之间，以阻尼在该扇区(32)相对于该支撑件(31)的相对运动。
摘要（英）：

A turbine engine turbine ring, in particular for a helicopter, in which vibratory behavior is reduced. The turbine ring includes an essentially cylindrical support, and one or more sectors forming a circle configured to define a segment of an air passage, each sector being fastened to the support by an attachment device, wherein the attachment device includes a hook portion belonging to the support and projecting towards the sector, and a hook portion belonging to the sector and projecting towards the support, the hook portions of the support and of the sector being configured to co-operate in order to fasten the sector to the support, the ring further includes a damper device provided within the attachment device and stressed radially between a portion of the sector and a portion of the support so as to damp relative movements between the sector and the support.
