“The diesel is the great grandfather of the jet engine.
Explanation please.”
The idea of jet engine combustion originated in the diesel design. Both engines are unthrottled, and take in a full charge of air continuously. The air is compressed, and fuel is injected into the superheated (by compression) air resulting in combustion. Power is increased by injecting more fuel, intake air is unthrottled.
Turbocharged diesel design can lower the compression ratio as their turbo boost is increased. Taken to extream, the turbocharger becomes dominant, and the piston becomes immovable, resulting in a burner can instead of a compressiion cylinder containing a movable piston.
Keep upping the size of the turbocharger and size of the burner cans, and you increase the thrust of the engine exhaust. Shaft power can be tapped off the turbo shaft if need be.
