How did the gas turbine built in Paris in 1903 demonstrate that gas-turbine engines could work?

The 1903 gas turbine built in Paris demonstrated the feasibility of a practical gas-turbine engine by successfully integrating three core components: a three-cylinder, multistage reciprocating compressor, a combustion chamber, and an impulse turbine.1

In this system, the compressor supplied air that was burned with liquid fuel in the combustion chamber. To manage the resulting temperatures, the gases were cooled by water injection before being directed into the impulse turbine. Although this machine achieved a thermal efficiency of only about 3 percent, it provided the first empirical proof that such a system could function as a self-contained prime mover.1
