The study describes a special construction of a pulsating self‐compressing combustion system, which gives nearly constant in‐ and outflows of gas, and its use in connection with gas turbine power stations. The main idea of the self‐compressing combustion chamber is that the pressure at the outflow after combustion is higher than that at the inflow to the combustion chamber. The maximum thermodynamically possible pressure rise in the combustion chamber is solved and calculated for different temperature ratios and combustion processes. The thermodynamic advantage of pulse combustion for gas turbine systems is shown as a function of the self‐compression pressure ratio.
