Abstract
An example turbomachine probe assembly includes a probe body extending along a probe axis from a first sensor end to an opposing second end. An eccentric retention feature is configured to engage the probe body into contact with wall having an aperture that receives the probe body. The eccentric retention feature limits movement of the probe body along the probe axis relative to the wall.
Claims19
A turbomachine probe assembly, comprising:
- a probe body extending along a probe axis from a first sensor end to an opposing second end;
- and
- an eccentric retention feature including a post extending along a retention feature axis from an eccentric lobe that is offset from the post, the eccentric retention feature configured to engage the probe body and to contact a wall having an aperture that receives the probe body, wherein the eccentric retention feature is rotatable against the wall about a retention feature axis to limit movement of the probe body along the probe axis relative to the wall, the probe axis transverse to the retention feature axis.
A turbomachine compressor case assembly, comprising:
- an annular compressor case provided about a rotational axis of a turbomachine;
- and
- a plurality of probe assemblies each having
- a main body portion,
- a lip portion,
- at least one eccentric retention feature including a post extending along a retention feature axis from an eccentric lobe that is offset from the post, wherein the main body portion is received within a respective aperture of the annular compressor case, and the at least one eccentric retention feature engages the main body portion such that a portion of the annular compressor case is positioned radially between the eccentric retention feature and the lip portion, the eccentric retention feature being rotatable against the annular compressor case about a retention feature axis to limit radial movement of the probe in a radial direction, the retention feature axis transverse to the radial direction.

A method of retaining a probe within a turbomachine, comprising:
- inserting a probe body within an aperture of a turbomachine case;
- capturing a portion of the turbomachine case between a lip of the probe body and an eccentric retention feature engaging the probe body;
- and
- rotating the eccentric retention feature against the turbomachine case about a retention feature axis to hold the probe body relative to the turbomachine case along a longitudinal axis of the probe body, wherein the eccentric retention feature includes a post extending along the retention feature axis from an eccentric lobe that is offset from the post, wherein the retention feature axis is transverse to the longitudinal axis of the probe body.
