Blue Eagles/Lynx ?? - Don't stop me now video

[Arclite01]

Anyone remember a video (I think it might have been on Noel Edmonds programme) of a Lynx doing loops and stuff to the track 'don't stop me now' by Queen ?

Anyone know where we can get a copy.

Thanks

Arc

The track was 'It's a Kind of Magic' - My suggestion if I remember correctly I didn't know there was a vid...

I've hosted that one here, along with a few from 847NAS .

Large downloads, beware

Thanks guys

great stuff but my other (better ?) half insists it's 'don't stop me now' (unfotunately I think she's right too.....)

and yeah that second download is massive !!!!!

cheers

Very good to see Sgt Julie (chewing gum) Wiles, as a display pilot - when do we get SNCO pilots back into the RAF now that we no longer carry US nuclear weapons? The 2 man principle has been defunct for 16 years!

Just to ask a question I've often wanted to ask, why or how does a Lynx manage loops when other (?) helicopters can't or don't ?

[Zoom]

It's all to do with its rigid rotor. That's it. That's all I know. (Cue some chopper mate who knows a lot more about it than I do.)

Lots of Helicopters can loop, including Gazelle and even CH53.
The difference is that you have to get it right everytime or chop your tail off and die in most, and in a Lynx you cannot chop your tail off.

[Two's in]

Most helicopter blades are attached to the Main Rotor head via physical horizontal and vertical hinges, the horizontal hinges (fwd and aft movement of the blade from the extension arm) have a drag damper to control the movement, but the vertical movement (up and down movement) of the blade is a function of aerodynamic forces, other than a droop stop stopping it going down too far. The Lynx, by comparison, achieves this with a rigid Titanium extension arm that holds the blades in place, and all vertical and horizontal movement of the blade is a function of the flexing action of the titanium. The reaction of the controls input is far more rapid with a rigid head (and is actually damped out by the AFCS), but when inverted, the blades can not "clap hands" as they can with a conventional head when negative G is encountered, because the titanium head holds then in place. The secret of rolling or looping in conventional helicopter is holding positive G, so the aerodynamic force on the blade (which would force the blades to "cone" up into a V, relative to the fuselage) is countered by gravity. As Tourist says, failure to maintain positive G usually results in the rotor cutting off some fairly important bits down the back end and a guaranteed seat (posthumously) at the BOI.

The Gazelle was limited to max 90 degrees in Pitch/Roll for this reason and the Elphinstone loop is actually an optical illusion, in that it stays within the pitch limits (usually). Although anyone who has seen the photo of the Gazelle over the (insert name of Large TV tower with cafe near Detmold, Germany) in 654 Sqn AAC crewroom knows that it will go inverted quite nicely.

Apologies to all POF buffs for simplifying the reply.

For spotters, when parked on the dispersal, blades on conventional heads always droop down, blades on rigid rotors stay erect.

Nice explanation, two's.

Why didn't they make groundschool that straightforward

Helicopters............








.......how sad.

Bitch!

But they really do 'bore for NATO' at airshows - as it was once described to me.

So your experience is vicarious? Most impressive.

[junglyking]

Boring for NATO...

Generally I would agree - but this years Wokka display at the VL airshow was surprisingly good.

Nice to see what it can do in the right hands - last time I saw someone try to throw it around there was a large thud and both tail wheels appeared and floated away off OCEAN's quarterdeck...

Thanks Tourist,
That's the H53, nearly big enough to fly a Gazelle inside. Got the video somewhere of if being rolled.

What I thought I had posted was the link to that very video.
