Fuel burn of Fokker, ERJ, 735 and 752?

[Tu154lover]

Hi!
Now I wonder (one more time) about fuel burn of these planes. The planes I wonder the fuel burn for is:
-Boeing 737-500
-Boeing 757-200 (RR with and without winglets)
-Embraer ERJ-145
and -Fokker 70/100.
Thanks,

F100 - 2500kgs in the first hour, 2000kgs thereafter. F70, take 200kgs off.

thank you for the quick answer!

The 757-200 burn is probably around 9,500 lbs per hour. With the winglets the drag factor is down -3.5%, not sure if the fuel burn is down the same number as in direct reduction also 3.5% (Different types of drag in affect)

ERJ 145 plan on a little over a ton an hour should do it. It's a frugal little beast really. Yesterday Scotland to Zurich 2:20 block 2:05 airbourne 1900kg.

D and F :8

Is the fuel burn lower on the Erj-145XR?

[SR-22]

Actually the 757-200W burns about 3500 kg p/hour with RB211

I would disagree with the comment above about the ERJ145 being frugal. It's fuel burn is spread over only 49 pax. It is probably optimal on routes of about 2 hours flight time, but there is a reason no one is building any new 50 seater regional jets. Production has moved to 70 plus seaters, anything smaller still cannot compete on fuel economy with the turboprops.

Regards.

Although you didn't specifically ask, the B200 figures about 800pph for the first hour, then about 600pph. :-)

B757-200 no winglets:

For 100,000kg TOW (typical 4hr sector):

4,800kg first hour
3,100kg per hour thereafter

For a B757-300 with 110,000kg TOW:

+400kg on above hourly rates.

Very very rough figures but for the 737-300 (i'm guestimating that figures for 735 will be slightly lower)

2 tonnes per hour (one tonne per engine) plus one tonne to reach top of climb.

So 2 hour flight needs 4 tonnes for the cruise and one more tonne for takeoff and climb so total 5 tonnes.

All dependant on winds, weight and so on and so forth

does anyone know the fuelburn of Emb-170/190 and Dash Q100 vs Saab 340B

[Dufo]

Saab 340A cca 450kg/h total at FL180 and 270 TAS.

A330 burns about 10.000kg/h on climb at around FL100...When reaching optimum cruising altitude it use to burn about 6000kg/h the few comming hours, then it slowly goes down to 5400kg/h...

A321 if having a 85t TOM then it would need around 15T fuel for a 3 h 15 min flight and landing with 5 tonnes...So fuel flow is around 3000-3100 kg/h.
