Fuel Flow Rate (FFR) in aircraft design is the rate at which an aircraft’s engines consume fuel to produce the required thrust or power. It’s a critical parameter for aircraft performance analysis, fuel planning, and operational considerations. The formula for Fuel Flow Rate and its definition are as follows:
Fuel Flow Rate (FFR): This represents the quantity of fuel consumed by the aircraft’s engines per unit of time, typically measured in liters per hour (L/h) or gallons per hour (gal/h).The formula for calculating Fuel Flow Rate is as follows:
- Engine Fuel Consumption Rate per Engine: This is the rate at which each engine consumes fuel, usually expressed in liters per hour (L/h) or gallons per hour (gal/h). It depends on various factors, including engine type, thrust settings, altitude, and airspeed.
- Number of Engines: This represents the total number of engines on the aircraft.
