Thanks for your support, folks!
So let’s quickly summarize what we know, and think metric:
Moe Syzlak’s Tornado in Reheat at LL circa 900 kgs/min
Tornado at 80% Rpm circa 120 kgs/min {i.e. approx 420 kts}
Moe Syzlak’s Harrier in Hover circa 250 lbs/min = ca. 113 kgs/min
Harrier at ~80% RPM circa 100 lbs/min {i.e. approx 420 kts} = ca. 45 kgs/min
Gary Lager’s B737-300:
Takeoff - 3000 kg/hr per engine = total 100 kgs/min
Cruise (at FL 3XX) 1100 kg/hr per engine = total 36 kgs/min
Silberfuch’s Shuttle
200.000 kgs/min
Onan’s C-172 11 gph = ca. 42 l/h = ca. 0,69 l/min = ca. 0,55 kgs/min
And flugholm’s B-Falke:
Cruise ca. 11 l/h = 0,18 l/min = ca. 0,22 kgs/min at a whopping 60 knots
Takeoff – not that much more fuel flow, but much more noise. (Now, don’t get me started on that…! )
