What powers the propeller to provide thrust?

Explanation:
Propeller thrust comes from turning its blades to push air backward. To rotate the blades, you need a power source, and that source is the engine. The engine converts fuel energy into mechanical power and drives the propeller through the propeller drive system, delivering the torque that makes thrust possible. The firewall is simply a safety barrier and doesn’t power the propeller, and while the powerplant refers to the whole propulsion system, the specific component that actually turns the propeller is the engine.
