SP should have control....

He should indeed, but he has declared Open House.

[jindabyne]

Have booked a very expensive country house hotel by Coniston Water

There isn't one! See you in the Black Bull

[SincoTC]

Well at least this one was intended to fly! Sorry, I'll get me coat.....

[safetypee]

Something vertical, with more than one of these engines?

Re the small disc-sectors on the external ring at base of the exhaust, are these thrust trimmers?

[SincoTC]

Morning safetypee, good call on LM's Bluebird !

Something vertical, with more than one of these engines

Correct on both counts, but I have no idea of the function of those semi-circular shaped parts, initial thoughts were brackets for a nozzle extension but if so, why would they be oddly spaced, they also seem to vary from engine to engine! They're rather small, but maybe they have some influence on the flow/noise, possibly at max thrust, pehaps someone can enlighten us?

BTW, I'm after the engine type and aircraft.

[Lightning Mate]

Morning.

pehaps someone can enlighten us?

I think safetypee is correct. They appear to be exhaust gas temperature trimmers, but there are rather a lot of them.

Something vertical

Still trying to work out what that means......Helo?

[JEM60]

Something vertical,like a Shorts S.C.1 or Flying Bedstead, perhaps.?

[SincoTC]

Good morning gentlemen (and evening Graeme if you're lurking)

At work now, but will monitor as often as possible.

Not a Helo LM, JEM60 is on the right track but it's not one of those two.

[Lightning Mate]

Off we go then.

Bell Model 65 Air Test Vehicle?

[SincoTC]

Sorry David, not the Bell 65 ATV

[Lightning Mate]

Another shot....German/Russian.

[SincoTC]

That narrows it down a lot mate, it is one of those two !!

[Noyade]

Morning.

Thought VAK 191...but now Dornier Do 31?

[Lightning Mate]

Evening Graeme.

"two vertically mounted engines"

A Yak 36?

Maybe the engines are RKBM Rybinsk RRD-41 liftjets.

[SincoTC]

Evening Graeme,

Yes mate, it is one of the six RR RB-162 lift engines in the Dornier DO-31

Noyade has Control

[Noyade]

Thanks Trevor. Concentrated on the VAK 191 and found a photo of it in a museum...and next to it was the Dornier.

OPEN HOUSE.

[Lightning Mate]

I always loved reheat.....hooligan kit.....

[safetypee]

Reheat – a very British term. Always required for Thrust, and often to get supersonic, but not necessarily to get airborne.
Or just a lost Phantom of my memory?

[Lightning Mate]

I just love the way you answer things.

Imagine a Lightning with two Avons in burner, and you're only 21 years old.

The thread is all yours.

For the those lacking imagination - the 'Thrust SSC' supersonic car which used two RR Spey engines:
Thrust SSC | Flickr - Photo Sharing!

Even with a vivid imagination, my record was only 195kts during takeoff with O/W jugs at a 6000ft alt airfield in Iran!
You could ponder the ground speed at the time as well as what the squadron was doing in that part of the world.

Open House – currently on ‘Atlantic’ time.
