The two aircraft are obviously aerodynamically very different since the helo flies that speed with just 15/14=1.07 or 7% more power, assuming that fuel consumption goes approximately linearly with power. (I take it that LPH is the amount of fuel per hour)
LPH= liters per hour.
Yes, these 2 numbers clearly ilestrate the draggyness ofa gyro.
Seems like at lower weighs, Gyros are the winner.
Not weights, but air SPEEDS.
If i nailed the ferel to 75kts, not only would it be orrible uncomfortable after an hour, but the fuel burn will go to bout 20LPH
The best the ferels ever dun [ approx] at full fuel n bout 35 mph is bout 9LPH. The CH-7 wont even break ground burn'n that much.
Also, the ferel can putt round at 3800 erpm, the heli is constant at 5300 i think.
I was also assuming similar faired cockpits.
The majority of the gyros drag comes from the 'back leaning' rotor.
Pods do make a difference, but not much.
At low speeds it makes no difference.
Kolibri, that's over my head. But it looks like those numbers say 'advantage helicopter.'
Miles per gallon, the choppy is miles in frunt.
Hours off the ground per gallon, the gyro of similar weight is just better.
[ its the latter that counts dureing mustern.]
I'd have to say that cruising at 80mph at 3gph would beat cruising at 100mph at 6gph. Agree or disagree?
Depends on whos waitn at the other end for you.
Bloodyell, that makes the choise easy.
Ill take the choppy, with copilot.
