COTSTEM developed an optical sensor system for measurement of total temperature in gas turbines at temperatures up to 1700C.

The main deliverable from the project was a prototype sensor system integrated into a test engine. The completed system provided significant benefits for engine design and operation leading to reduced weight and lower specific fuel consumption. The sensor was based on well established optical principles using novel materials to survive the harsh environment.

The project built on Oxsensis existing expertise in harsh environment optical sensors established through the development of an existing pressure sensor for use in gas turbine combustion monitoring and control.

COTSTEM is a single partner project with the majority of the work to be carried out in-house by Oxsensis. Oxsensis applied existing project management practices which have been successfully used on similarly sized completed projects in the aerospace, power generation and automotive sectors.
