i need to finish a project about airplanes, and to have a specific detail I want to include the gas cost?
Need more detail…. gas for what? per litre? per hour?
Too many variables mate.
Rough fuel burn estimate:
Well, first you need the SFCs (lbs fuel/hr/lbs thrust) of both A320 engines in cruise (finding SFC figures for takeoff/climb is a bit tricky, so you’ll have to satisfy yourself with just cruise for now)…
CFM56-5A1: 0.596
IAE V2500A1: 0.581
…then, take the typical cruise thrust…
CFM: 5000 lbs
IAE: 5070 lbs
…and finally, multiply the SFCs for each engine by their typical cruise thrust to get raw ruel consumption…
CFM: 0.596 X 5000 = 2980 lbs fuel per hour
IAE: 0.581 X 5070 = 2945.67 lbs fuel per hour

Not sure of the fuel burn but Jet fuel prices are generally between $5/gal and $7/gal in the US right now. Most airlines have pre-negotiated fuel rates with the vendors so they don’t pay the sticker price. In addition, they don’t pay the sales tax on gas because they are considered “interstate commerce”.
