To better understand the processes occuring in a combustion chamber, for example in power plants or aircraft engines, and thus to design environment-friendly and reliable combustion chambers, the DLR Institute of Combustion Technology has developed a high-speed laser measurement system that can determine the flame characteristics during combustion in gas turbines with high precision: it is 1000 times faster than previous methods and, for the first time, shows what happens to the flame in the combustion chamber in great detail.
