I'll stick one in, if you don't mind!:E

Oww, seriously used and abused.
Is it a twin spool engine?

gas path 5th Mar 2012 21:24

Damn and blast. I been sussed! No it's a triple spool so that narrows the field down a bit!:}

dixi188 5th Mar 2012 22:52

RB 211 (anything from -22 to -524E4)

"Just blend out the damage and return it to service"

She'll do a trip!

OH if correct.

Harley Quinn 6th Mar 2012 04:23

I was going to go RB199- I remember hearing that they would shed turbines more often than not.

@dixi188

RB 211 (anything from -22 to -524E4)
Nearly right, but missed by a generation. It's the (remains of!:E) an RB211-524g engine. IIRC suffered a surge on take-off where the FAFC was scheduling more fuel to try to overcome the drop in P3 pressure.

open house!

One from up my sleeve.....

OK. This is an air intake? Something of the Air Cobra, P51 Mustang size shape and build? Unless of course its one of those Rocket assisted take off packs from the Strato Bomber days?

Lightning Mate 6th Mar 2012 12:04

It is an intake, but from neither of your suggestions. :)

Lightning Mate 6th Mar 2012 12:29

Piston engined aeroplane.

Never entered production.

trucky04 6th Mar 2012 12:35

Russian. Variant of the Mig 3?

Lightning Mate 6th Mar 2012 12:36

Not russian.

SincoTC 6th Mar 2012 12:51

A'rtnoon LM,


One from up my sleeve.....
That's odd, I'd have thought it might have been pinned to your Tie :)

First visit in a couple of days, I have been (and still am) heavily involved with business wallah's so can't stake a claim on this one, but my suggestion may help it along if it's what I think it is.

Catchya later and Graeme too I hope :ok:

Lightning Mate 6th Mar 2012 13:16

You've got it without a doubt TC. :)

Pity you're all tied up.......

MReyn24050 6th Mar 2012 14:36

Well with clues like that it can only be the Martin Baker MB-5.

Lightning Mate 6th Mar 2012 14:40

'artnoon Mel. :)

You know me - no point in making life difficult.

The MB5 it is - your control. :ok:

Be gentle with us........

MReyn24050 6th Mar 2012 14:49

Thank you David.

Be gentle with us........
Well here is a nice easy one:-

Lightning Mate 6th Mar 2012 15:02

Looks like it's from 1890!

MReyn24050 6th Mar 2012 15:04


Looks like it's from 1890!
:) :ok: :) Give or take a few years.

Lightning Mate 6th Mar 2012 15:21

The only thing I know with an exhaust like that was a project and never flew.

MReyn24050 6th Mar 2012 15:29

This aircraft was produced in numbers and certainly saw Squadron service.

Lightning Mate 6th Mar 2012 15:32

French....?

MReyn24050 6th Mar 2012 15:48

This one was not from France.

Noyade 6th Mar 2012 20:23

Evening Mel.

Quick punt...the North American Savage? Can't find any decent rear shots of it, must have been a shy creature. :)

(Yes Mel - unfortunately I typed Boeing XF7B-1 :( )

MReyn24050 6th Mar 2012 22:59

Well Graeme for a quick punt, it was a very good punt as it is the North American Savage AJ-1

The date of its design inception was a time (late 1940s) where the US Navy was faced with procuring the nascent jet engine, while still having to rely upon the simple yet well proven reciprocating engine. Jets at this time were unreliable and used large quantities of fuel; however, once they were developed, they produced performance that no piston engine could ever provide. A compromise was made to include in the Savage two Pratt & Whitney R-2800 piston engines, with a large turbocharger fitted inside each engine nacelle. This combination made it possible for the R-2800 engines to produce rated power (2,500 hp/1,864 kW) up to 42,000 ft (12,802 m) altitude. An Allison J33 turbojet was fitted in the rear fuselage. Interestingly, both engine types used the same fuel. The piston-turbojet arrangement was intended to give added power on take-off and extra dash speed while in combat. At high altitude, this "boxy" looking (but aerodynamically very clean) airplane was remarkably fast, reaching more than 460 mph (740 km/h), when the jets of that era were not very much faster.

You have control.

Noyade 7th Mar 2012 04:41

Thanks Mel. I'll only be on sporadically for the next week, so open house.

Lightning Mate 7th Mar 2012 13:54

Too long at OH...

Kitbag 7th Mar 2012 18:16

How about the Northrop Snark?

Lightning Mate 7th Mar 2012 19:03


How about the Northrop Snark?
Go back to search mode mate. :E

Kitbag 7th Mar 2012 20:02

The more I look the more closely it appears to resemble a turboprop intake.

Lightning Mate 8th Mar 2012 07:18

Not a turboprop mate.

trucky04 8th Mar 2012 10:30

With the lack of "warning jet intake" and the fact it is not a turbo prop, could this simply be a piston engine? Secondly, the trim markings look simply 'civilian'. Lastly. Is that a landing gear I spy in the back ground and if so, does it suggest more than one engine?! Hope I haven't tried to winkle too many clues!

Lightning Mate 8th Mar 2012 10:38

It's a jet engine trucky.

Not strictly military, and yes, you do see part of the landing gear.

Wannanuther clue?

trucky04 8th Mar 2012 13:17

With the square shape intake it suggests under wing mounted? Also, was this primarily civilian/biz jet with the exception of a few going to the likes of coast guard etc?

Lightning Mate 8th Mar 2012 13:20

The intake is under the front fuselage.

Not a civilian/biz jet - not coast guard.

Try NASA. ;)

MReyn24050 8th Mar 2012 13:36

NASA Dryden's F-16XL-1 perhaps?

Lightning Mate 8th Mar 2012 13:39

Sorry Mel but no.

Would you like another clue in view of your generous one on What Cockpit?

MReyn24050 8th Mar 2012 13:50

NASA Himat perhaps. I gave the generous clue on Cockpit because it was dragging on a bit and it was going to be a case of attrition for every Heinkel produced pre WWII.

trucky04 8th Mar 2012 13:54

Its the NASA experimental HiMAT aircraft. OPEN HOUSE if correct

trucky04 8th Mar 2012 13:55

I should F5 more often!!!
