A method for detecting flameholding in at least one combustor of a turbine engine includes measuring dynamic pressure data of the at least one combustor of the turbine engine; converting the dynamic pressure data to frequency-domain spectral energy amplitudes for the dynamic pressure data; and comparing the spectral energy amplitudes against a dynamic amplitude threshold value to determine whether the amplitudes exceed the threshold minimum amplitude value, wherein exceeding the dynamic amplitude threshold indicates a flameholding occurrence.

Methods and systems to detect flameholding in turbine assemblies

A method is provided for the autonomous assessment of pipelines. The apparatus combines commercially available mechanisms for pipeline assessment in a unique untethered pipeline assessment device that is propelled through the pipeline by the flow of liquid in the pipeline, thus allowing for the assessment of pipelines much cheaper, faster, safer and less disruptive to the community than the current assessment methods.

Apparatus for autonomous pipeline assessment

A method is provided for the installation of varied sewer rehabilitation lining materials within an existing sewer while conveying sewage flow through an internal bypass contained on a sled that applies the rehabilitation materials, thus eliminating the need for an expensive, intrusive above grade external bypass. The apparatus is compatible with the various rehabilitation materials, technologies and methodologies currently available in the industry. The method and apparatus can be utilized to restore the original structural integrity of a sewer pipe or to provide a corrosion barrier. Multiple and varied rehabilitation materials (including but not limited to epoxy, geopolymer, mortar, cement, etc.) can be applied using the same apparatus. The apparatus can also be utilized to clean and televise the sewer prior to and during the rehabilitation process.
