The hot section of the turbine is much smaller. That's how you burn jet fuel at 2,000 degress. The back end drives the front by being connected by the same shaft. The front end is the compression it's much bigger and air is compressed down. When air is compressed it cause jet fuel to burn extremely hot and develop thrust.......

That's the size I would expect to see on a turbine from the hot section, especially on a high bypass engine, we're most of the compresed air bypasses the hot section.
