In flight mechanics, the term “change in energy” typically refers to the alteration in the energy state of an aircraft or system as it undergoes various maneuvers or flight conditions. Energy changes are crucial for understanding and analyzing aircraft performance, efficiency, and the physical processes involved in flight.
- dE: Change in energy (often measured in joules, J).
- dWf: Change in the amount of fuel consumed (typically measured in kilograms or liters of fuel).
- N of fuel/h: Fuel consumption rate, representing the amount of fuel consumed per unit of time (usually measured in kilograms per hour or liters per hour).
