The 225 burns 16 tons of fuel per hour while flying. This airship has 4x 325 HP V8 engines. Roughly speaking they each use about 150lbs of fuel per hour to generate 325 HP. That's 0.3 tons per hour between the four of them. Now of course the 225 will do 5x the speed of the Airlander 10, so where the 225 would use 16 tons to go 500 miles, the 10 would use 1.5 tons. Here's where things get interesting, though. The frontal surface area tends to dominate drag, where as the volume is what gives you lift capacity. You can scale volume much faster than frontal area and that means 10x (or 100x) the lift capacity might only be 2x (or 10x) the fuel consumption. Big-Oh(airship) is potentially interesting.
