Abstract

Over the last several years, the development of coherent anti-Stokes Raman spectroscopy (CARS) has progressed through simple flames of increasing complexity to practical application in internal combustion engines, simulations of gas turbine combustors, and a variety of other devices. Here, the first application of CARS to an actual afterburning jet engine is described. The CARS instrument constructed is capable of completely remote operation and permits instantaneous thermometry at a 20-Hz rate. Its design and operation as well as sample exhaust measurements will be presented.
