Horsepower is a unit of measurement used to quantify the power output of an engine, particularly in relation to its capability to perform work over time. It connects closely to how effectively an engine can convert fuel energy into mechanical energy, which is crucial for understanding engine performance and efficiency in aircraft design. This measurement is essential in evaluating the relationship between engine power and propeller efficiency, ultimately influencing aircraft performance and operational capabilities.
