Adjustable mounting device for aligning optical sensor in gas turbine engine combustor

A mounting device for adjustably retaining an optical sensor on a combustor basket of a gas turbine engine, the mounting device comprising:

• a base structured to be mounted on the combustor basket, the base being formed with a socket,
• an alignment member formed with a ball, the ball being adjustably received in the socket, the alignment member being structured to carry the optical sensor;
• and
• a clamp mounted on the base, the clamp being structured to apply a non-rotational clamping force to the alignment member to clamp the alignment member in a given orientation with respect to the base;
• in which one of the clamp and the base includes a compression ledge that is compressively engageable with the ball, the compression ledge including at least a first protrusion.

A turbine engine comprising:

• a compressor section;
• a combustor section;
• and
• a turbine section;
• the combustor section including at least a first combustor basket;
• a base structured to be mounted on the combustor basket, the base being formed with a socket;
• an alignment member formed with a ball, the ball being adjustably received in the socket
• an optical sensor mounted on the alignment member;
• and
• a clamp mounted on the base, the clamp being structured to apply a non-rotational clamping force to the alignment member to clamp the alignment member in a given orientation with respect to the base.
