Turbine D:
thanks - your clear explanation + some web search produced much better understanding that the combustor tech can be very simple (available to enthusiasts) or complicated (professional big power aeroturbines). But the vibrations may be contained and to certain extent controlled.
Is LCF based on using cooling airflow, protective coutings, disposabe elements to prevent temp buildup or polishing and rounding the edges to prevent cracks? Most probalbe a mix of the above but are there any other interesting techniques?
