I hope it doesn't have the teething problems the E model did. The echo,was savaged in the media near the old Marine base at Tustin Ca where I grew up. The local paper there had a hard on for it.

"Rolling out" may or may not mean putting that monster into the air.

The ground test vehicle went live on 17 April, but I seem to recall that it won't leave the earth. That beauty in the pictures here may fly soon.

Huzzah!

Why is the tailplane canted to port?
Something to do with a weird torque vector?

Aye. A propper chopper.



Does a -53 always go on top?..

Why is the tailplane canted to port?
'Twas ever thus on the Super Stallion. One would guess to give a bit of extra lift at the rear, I'm sure the boffins in white lab coats know their stuff. From http://www.airvectors.net/avskbig_2.html

Although the prototypes were built with a wide-span, low-mounted symmetrical tailfin, flight control problems led to refitting the second machine with of a distinctive new tail assembly, with the tailfin canted to the left by 20 degrees and an inverted-gull asymmetric tailplane mounted on the right. This change was used in production S-80s.

A wee tiddler compared to the Mi-26. I read once max underslung load of Mi-26 is 56 tonnes so it could possibly lift the CH-53

Melmothtw, you can take off half of the main rotors on a Ch53 and still fly it, i'd like to see you do it with that hunk of junk

But wouldn't the vibes be a real bugger?
(Tourist, hee hee, well played )

The Black Hawk / S-70 family also has a canted tail rotor, which (according to our old NATOPS manual for the Seahawk) provides up to 2.5 percent of the total vertical lift.

CH-53K: oh, what a beautiful beast! I will go out on a limb and suggest that Igor his own self would be mightily pleased with the King Stallion.

Lets hope they dont try to roll this one ...the last time didn't end well.

Amazing machine the " homer" shame only two built, but when the soviet air force says niet you know you have problems!

Any one know if the eu / uk heavy lift competition still going on, i seem to remember a supersize euro tandem twin design being flashed about..... This and the king would be an interesting sight

Yep, this is true. I was lucky to work at Sikorsky in Stratford C.T. from 1987 to 1989. Jimmy Kay was the Sikorsky test pilot who was flying at the time this photo was taken ( I have a signed black and white copy at home) He said that they had a slight vibration @80knts and around 110 knts but everything else was smooth flying.

Is that as close as Sikorsky can get to a BERP blade without paying the UK royalties?

Nutloose: neat, had no idea they'd done that.

VX: I'd need to look at some more images of the BERP. Various manufacturers have been messing about with blade tips for decades. I am not sure I see how the blades shown on the K are a BERP copy. There's a lot going on there, it looks like from the photographs available.
