Measuring acoustic transfer matrices of high-pressure hydrogen/air flames for aircraft propulsion. Combustion and Flame, 2024; 270: 113776 DOI: 10.1016/j.combustflame.2024.113776 ...

In typical jet engines, about twenty fuel injection nozzles are arranged around the annular combustion chamber of the engine. The turbulent combustion of the fuel there generates sound waves.

The conversion is aimed at reducing maintenance costs. The double annular combustor (DAC) was first applied to the CFM56-5B in the 1990s to reduce nitrogen oxides emissions.

In brief In jet engines, the interaction of flames and the sound generated by combustion can cause vibrations. These vibrations put a heavy strain on the engines. Engineers therefore do everything ...
