...What was a tipical fuel consuption per hour for the Concorde?...
A total fuel load of 91,000 kg, with a flight time of 3h:20m in the air, was a fairly typical flight plan for Concorde on a LHR-JFK flight.
Reserve fuel (minimum fuel required to be in tanks on landing) was 6,500 kgs, and the (hopefully unused) diversion fuel was usually somewhere around 3,600 kgs, so after an uneventful transatlantic flight Concorde would have expected to land at JFK with somewhere around 10,100 kgs fuel still remaining in tanks.
Allowing for the taxy fuel used whilst on the ground, this means around 80,000 kgs of fuel was burned in the air, giving an average consumption of 24,000 kgs/hr.
However, her fuel consumption could vary a lot, depending on the phase of flight.
Consider the fuel used during her earlier re-heated take-off at LHR:
- LHR....ISA....MTOW....V2.... 215 kts....20,700 kg/hr/eng....Total....82,800 kg/hr
- Start of Roll to Reheats OFF....83 seconds....Fuel Used: 1,909 Kg / 4,209 lbs / 526 g
You can see why the re-heats were turned off as quickly as possible!
