Fuel consumption by Jetfighters

[tharun]

Here is the fuel consumption of fighter jets used by our airforce with regards to the engine specifications...
Formula for fuel calculation.
Pounds of Fuel per hour per pound of dry thrust
1 liter of fuel = 1.78 Pounds of aviation fuel
1 Kilo liter = 1000L
1 Kilo liter fuel price is 40000/- Rs
Every calculation is based on dry thrust

Rafale---11,250X2=22500 Lbf of dry thrust
12600 Liters of Fuel = 50,4000 Rs/-

Mig-29---11,230X2=22460 Lbf of dry thrust
12577 Liters of Fuel = 50,3104 rs/-

HAL Tejas----12,100 Lbf of dry thrust
6776 Liters Of Fuel = 271040 Rs/-

Your calculation seems too high if it is per hour.

I think jet does not use its max power all the time. As in car, you need power while accelerating, but much less power to maintain speed.

I think LCA can stay in air for 2 hours just on internal fuel.

Mig-29 and Rafale should be able to fly for 3 hours on internal fuel.

The cost of operating an aircraft per hour takes care of all costs: cost of buying, cost of storing, cost of fuel, and cost of maintenance.

I just gave information of fuel consumption and price to fly if jet fly at full engine specification NOT total cost of owner ship....

Yes, thats why your figures do not look correct.
