I thought I’d chuck this in, copied from the Aviation Forum, in answer to a question about the fuel consumption of the Avro Vulcan:
The Olympus 20201 fitted to the Vulcan has a fuel burn of 13,950 lbs/hr at maximum power (100-100.5%) at sea level on an ISA standard 15c, 1013.2mb day.
This equates to a rate of 55,800 lbs/hr for a Vulcan with Take Off power selected at the end of the runway. Quite a lot eh!
Quickly crunching a few numbers regarding the fuel burn and using Moggy’s figure of 60p per litre, this equates to £5.24 per second.
To put this into perspective though, in similar circumstances; Max power, lined up on runway etc….. a Tornado GR4 in max reheat is burning 6 gallons of Avtur per second.
