What is the primary goal of a fuel pump in aircraft engines?

The primary goal of a fuel pump in aircraft engines is to transfer fuel to the engine at the right pressure. This is crucial because aircraft engines require a consistent and adequate supply of fuel to operate efficiently and safely. The fuel must reach the engine at the correct pressure to ensure optimal combustion, which in turn affects the engine's performance, efficiency, and response to throttle changes. Maintaining the appropriate fuel pressure helps to prevent issues such as vapor lock or fuel starvation, which can lead to engine failure. Thus, the correct functioning of a fuel pump is essential for the reliability and safety of the aircraft's powerplant system.
