Sikorsky rolls out CH-53K
 

Aptly named King Stallion

Sikorsky Unveils CH-53K Helicopter; U.S. Marine Corps Reveals Aircraft Name


Cheers

That is one big motherf*cker of a helicopter.

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! :ok:

Super size pic of EDM 2, that rotor head is rather impressive!

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?..

'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

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

Pah, I'll see your Stallions and Halos and raise you a Homer!

I was wondering who nicked all my scaffolding...

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 ;)

Aye Nutloose, but try flying your CH-53 without a tail rotor...

Nutloose

Which half of 7 would you remove?

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

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. :8

CH-53K: oh, what a beautiful beast! :D 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

I never said which variant Tourist ;)

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. :ok:

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. :confused: There's a lot going on there, it looks like from the photographs available.

Don't try and stand near one as it either lands or takes off......

From chopper2004's link

What are they going to use it for? Short hops across the fleet when at anchor or summit?

BERP has always been far more than just the tip.

With 27,000 lbs of kit slung underneath. One would hope the mission radius is a little more when not carrying so much stuff...

Holy sh1t - I hadn't seen that barrel roll video.
I have heard it said that in terms of hands on cyclic and collective and feet on pedals, the big machines can feel surprisingly nimble to fly.
Spoke to a chap in NZ flying a Mil 8 on a logging op and he said `Mate, it's just like pole-ing a Squirrel around.'
Any Stallion drivers reading who could comment?
And yes Alf - had also heard that when one lifts off, it can blow you off your feet if you are watching nearby and not ready.

The few times I got to fly a CH-53E, under the watchful eye of a USMC Aircraft Commander, I found it smooth and very responsive to the controls. Great bird. :ok:

My late father, who was on EH101 design before moving on from Westlands, watched a CH -53 come in ,then depart, from the field in Yeovil many years ago .
His comment to me :

" Just what do we think we are playing at ? "

Alls sorts of barbs have been slung at Sikorsky various threads at pprune.

Yet when we look around the Western World and many of the other parts as well....we see the SK Products in inventories doing Yeoman work every single day in every kind of climate and environment.

I see those Critics as suffering from something akin to Penis Envy.

Many moons ago a French man was flying his little 152 to near Paris, but the weather got bad so he diverted to Le Touquet, an hour or so later, lost and running out of fuel he stuffed it down into a plowed field in Kent! He made a perfect forced landing with no damage, but it needed shifting from the field so it could be flown out, the USAF kindly sent a CH-53 to lift it and promptly blew it inverted, finally managing to do what the Frenchman couldn't... It came to us and we eventually rebuilt it, including replacing the whole of the rear fuselage.

When the CH-53E was being introduced into the Fleet, back in the 80's, they reckoned that with the hurricane force winds that the downwash produced, the LSE directing the bird over the deck in a hover needed to have his person attached to a tie down via chain and hook. :eek:

Also, the grounding wand was a pretty healthy piece of equipment! :ok:

Of course if you get a gear stuck then it's underneath and pull it out

Would be a good caption comp entry too

And of course the movie, same thing, different location

:ok: Nice job, loved the video. :D

Wow - great video. Obviously before the days of Health & Safety bolleux !

And Sikorsky Rolls It Back In
 

Sikorsky announced at least a six month delay in flight of the 53K due to a transmission design problems. How long was the first delay of the Canadian 92's?

The Sultan

How far behind schedule was the Osprey, Ding Dong?:ugh:

Osprey first flight was basically on schedule.

The Sultan

Basically? No groundings along the way either i guess?

I suspect that this set back was discussed in detail and agreed with the Program Manager. Not a surprise, but a disappointment. :uhoh: One would have thought that with the years of putting these things together and the known pitfalls in design, and as noted above, the recent experience with S-92, this design effort over the past few years would not have been caught out.

Then again, the entirety of helicopter design involves tradeoffs and compromises, and nowadays a bit of risk. Sometimes, that risk shows up in a "no, it won't work out" result.

Press on, team, and grind it out. (Wait, maybe not the best choice of words for a transmission issue. :eek: )

BB,

How can there be a grounding before first flight? Kind of a Sarah Palin moment for you!

Also no one with a passing hint of the 53 would try to compare its early (or later) safety record as a yard stick for how it is to be done.

The 53K is a derivative, but the revolutionary in every way V-22 was contracted in 1983 and first flew in 1989. The K was contracted in 2006 and will still be sitting on the ground in 2015 or beyond. Get someone to do the math for you.

The Sultan

All I know is I was on the top deck servicing a mighty puma :ok: at Benson when a Pave Low came taxiing by, festooned with guns and stuff, I had to duck and hang onto the engine to not be blown off the deck......

As Arnee once said " Get to Tha Choppa....."
