machine with the most power

[mikelimapapa]

hey rotorheads,

Im sure this will spark some debate, like most threads in the forum, but I was wondering which helicopter out there has power to burn? From what I read, the Gulfstream V in the fixed wing world has more power than it knows what to do with, so what would be the fling wing equivalent?

It must be the Chinook - an awesome machine. With full (airframe) fuel and about 25 pax it is still able to hover IGE on one engine on a standard UK day. Usually it bulked out inside before reaching MAUM (except with some special loads) and really only reaches MAUM with an underslung load.

Always a joy to fly, just the lifestyle that sucks.

Empty Chinook...well down on fuel....confined area takeoff..."Clear Left, Right, Overhead!"....Thrust Lever smoothly to the top...left pedal about half way to the stop...VSI pegged....vertical to 3000' AGL.....pulling about two G's till the lever is reduced...and people brag about good sex!

Nah...try an empty Mil Mi-26 ,which holds the world record for a windmill climbing to altitude and has real powerful engines ,and a cabin that you can load a Chinook into.
Having seen the pictures of one recovering a CH-47D from a high altitude crash in Afghanistan makes you wonder why the US Army is so determined to waste money developing a new HLH with the same payload !

na KA32 goes up like a rocket nearly makes your nose bleed

Thanks for the replies guys, 3000 fpm must be an awesome ride! But I was thinking more along the lines of your typical civilian pax helos. The nicest machine I've seen up close was a pristine EC135 that refueled at my school. Instead of taking off on the runway, he requested a fly-by of the school and must of been doing at least 100 kts down the taxiway. Just as he pasted the gawking students, he pulled back and shot up like a rocket!

The EC135 needed forward speed and a big pull back on the cyclic to register a climb?? :rolleyes:

The new AB-139 should be a real leaper. It weighs in somewhere near 13,200 lbs and has 3360 ESHP for takeoff.

India's re-engined Lama - the Cheetal - should also be interesting: 1,100 shp lifting only 4,300 lbs.

The S-70 Blackhawk is a pretty impressive heli too (ours were civvie registered with the -C engines).

21 pob, 2 hrs fuel and single engine OGE hover was nice to have. So was the 144%/144% Tq (max transient power) vertical takeoff performance. The quickest elevator in the south!

The cabin load of RAF Wessex pilots we demo'd it to didn't stop talking about it for weeks afterwards. Mind you, they used to takeoff along the runway, we took off over the fence and almost pinned 'em to their seats! :E

Your spot on PT6ER nothing will beat a Crane for power to burn and rate of climb even at VNE it will smoke a 234 or any other helicopter from a standing start it will beat a F4 to 10000ft.
