Quick Answer: How is aircraft fuel burn calculated?

Contents

The amount of fuel needed for a given flight can be calculated by multiplying the estimated flight time by the rate of consumption. For example, a flight of 400 NM at 100 knots GS takes 4 hours to complete.

How do you calculate fuel burn?

Divide mileage by fuel usage to see your car’s fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).

How do you calculate the specific fuel consumption of an aircraft?

The fuel mass flow rate is related to the thrust (F) by a factor called the specific fuel consumption (TSFC). The specific fuel consumption equals the mass flow rate divided by the thrust. (TSFC = mf / F ).

How much fuel does an aircraft burn per hour?

The plane will consume 2,508 litres of fuel per hour. An Airbus A321neo fuel capacity of 32,940 litre. If an Airbus A321neo burns 0.683 litre per second, Boeing 747 uses approximately 4 litres every second, which translates to 240 litres per minute and 14,400 litre per hour.

What is the formula to calculate fuel consumption?

The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.

How do you calculate specific fuel consumption?

Simple Method

1. Formula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight. …
2. 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
3. 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

What is specific fuel consumption in aircraft?

Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (kilonewtons, or kN). … It can have units of pounds per hour per horsepower.

How is aircraft endurance calculated?

Let us calculate the expression for endurance of a jet aircraft. For steady, level flight, TA = TR, minimum weight of fuel per unit distance cor- responds to a minimum TA/V . Kindly note that, since TA = TR, hence range of aircraft (with jet engine) will be maximum if N(fuel)/m is minimum or TR/V is minimum.

How do you calculate fuel consumption per hour?

Calculate your average speed by dividing the number of miles you traveled by how long it took you. For example, if you traveled 200 miles and it took you 4 hours, then 200 / 4 = 50 miles an hour on average. Divide your average speed by the miles per gallon to find how many gallons per hour of fuel you’re burning.

How much fuel does a 787 burn per hour?

A Boeing 787-9 burns about 5400 litres of fuel per hour. At a cruising speed of 900km/h, that equates to 600 litres/100km.

How much jet fuel does a private jet use?

So, in conclusion, private jets will burn anywhere from 50 gallons of fuel per hour, all the way up to 626 gallons per hour. Of course, keep in mind that these figures are based on the average fuel consumption. Therefore, if you were to look at the burn during take-off and climbing, these figures would be much larger.

How much does it cost to fill a Boeing 747 with fuel?

On average, aircraft fill up with an estimated 3,500 gallons of jet fuel, costing an estimated \$7,070. However, price can vary from \$4,040 on the low end to \$14,140 on the high end.

How do you calculate fuel cost per km?

If you know the price of fuel, then you can simply multiply the price per litre by the result and that gives you your cost per 100km. E.g. if fuel is \$2, then 8.98l/100km means that it takes \$17.96 of fuel to travel 100km, or around \$0.18 per kilometre, not including your other costs like wear and tear.

How does L 100km calculate mpg?

To calculate your average fuel economy, divide the number of liters (49) by the distance travelled (540) and then multiply by 100. That’s it! In this case, the result is 9.07 L/100 km.
