I haven’t seen anyone else post about it, so here goes….
Il-2 flying in Novosibirsk……

I would be surprised to see this go to Flying Heritage due to the non-original engine. Yagen seems more logical……anyone know for sure?
See post #67. If you know who Steve Atkin is, you know it isn’t going to Yagen.

Thanks JDK for confirming my post.

It is my understanding that America used to drive on the left of the road in some States,if not all in the early days of motoring.
If you want to actually get a very interesting bit of history right, rather than having a boring old ding dong, look here. The page is mostly correct*.
http://en.wikipedia.org/wiki/Right-_and_left-hand_traffic
It’s off topic, too.
[*The near-enough true joke not included says that the British drive on the left, the Americans on the right, and the Maltese in the shade.]
On topic, does anyone know what differences there are between the installed engine and the original type, primarily in size, shape and ancillary set up? What changes may have been needed to the nose and mount to fit it?
TIA,

This aircraft is definately not destined for Mr Yagen’s collection in Virginia.

I hope you arent calling brits backward my dear boy 😉 Racial slurs and all that :diablo:
That siad we drive on the correct side of the road, as do the japanese 😉

My point exactly.

One of the two Allisons in a P-38 turned “backward,” which of course is like talking about Brits who drive on “the wrong side” of the road… Perhaps they used P-38 blades?

Being as the discussion has touched on P38’s, I thought I’d better post to clarify that almost all P38’s had handed props…
All other P38’s had outwardly handed props except for the small batch of export examples intended for use by the RAF which had both props right-handed. In the end these weren’t delivered and most were used by USAAF units back in the States.
So it could feasably be a left-handed P38 Allison in this Il-2…
Thanks for the clarification! I guess I had the “almost-Brit” Lightnings stuck in my aged brain. :rolleyes:

Being as the discussion has touched on P38’s, I thought I’d better post to clarify that almost all P38’s had handed props. The XP38 prototype had ‘inwardly’ handed props, but the downwash was thought to cause tail buffetting probems, although it was actually the wing root design that was to blame (eventually cured by fitting more streamlined wing root fillets). All other P38’s had outwardly handed props except for the small batch of export examples intended for use by the RAF which had both props right-handed. In the end these weren’t delivered and most were used by USAAF units back in the States.

Oh dear! There are some sensitive little petals here!:(
I was trying to be light hearted and not overly technical in my description of the propeller rotation.Anyway, back to the subject…
Reversing the direction of an Allison from R/H to L/H tractor basically involves disassembling the engine to swap the crankshaft end for end, swapping some drives end for end and repositioning a couple of idler gears in the accessory housing, repositioning the reduction gear oil jet and scavenge inlet and rewiring the distributor for the altered firing order.
Now, it would be nice to know, for my own technical curiosity, if these guys have fitted a L/H rotation Curtiss Electric propeller, or have come up with a different solution.For the record, the vast majority of P-38’s had handed engines for aerodynamic reasons I believe.
Unfortunately its not as simple as that re. prop direction, as depending on the mark of the engine the prop sometimes turned in the same direction as the crank and on others the opposite. IIRC the RH engines (crank rotation ) could turn the prop in either direction depending on how configured. Edit to add, configured at the factory, not swapped around out in the field.

I read somewhere it’s destined for Paul Allen’s Flying Heritage Collection, to keep some company with the 109Emil, 190A8N, 190D Dora, 163 komet, ki 43oscar, P47 jug, I-16 Rata and P40 Warhawk. Nothing on their website though..
By: Mark V - 13th October 2011 at 08:47
Surely some of these remain.
Kermit Weeks had a large collection of Allisons which could be purchased – there were a large number of opposite rotation Allisons in that batch as I recall, over a dozen I seem to remember… so yes, they can be found.

Avro, I am sure that your technical description here is quite right. However, would it not be easier– and thus more likely– if the Novosibirsk team simply sourced an anti-clockwise turning Allison? Surely some of these remain.
Many, many years ago I spoke to a chap who raced those fast boats on a lake in Seattle, USA. He told me that he always attempted to use such motors in his boat, as “counter-clock ’17s were a d***** sight cheaper” (to quote his own colourful vernacular).
As to the direction of prop rotation.. it’s a funny one. How many forget than many British engines turn this way? Griffon Spits, anyone? It is curious to me that clockwise rotation is seen to be so common.

a little NORTH American humour. – apparently lost upon some.
Not lost upon me 🙂

I think you will find that most were (and still are, in the case of surviving examples)
Yes, I was aware that “Glacier Girl” indeed has handed Allisons – but I thought that the later Marks had dispensed with that, for initial costs, and ease of field maintenance, etc.
And I HAVE been edified, today. I was under the mistaken impression that Hisso/Klimov’s rotated as do the US-built V-12’s…. not the UK types.
By: Canuck - 12th October 2011 at 22:12
Clockwise (viewed from the pilots seat) – in both hemispheres!
Yes, that’s what they appear to do, when I looked last week… and VWoC’s are both RR and Packard-based. 😀
Now, the Hemisphere reference was a salute to Antipodean loo’s btw… a little NORTH American humour. – apparently lost upon some.

Actually, I believe most Lightnings weren’t “handed”. 😉

Your comment said nothing about the PROP being the same as the one on the Monino example, only that they both turned clockwise as seen from the front…
Not sure either how you can tell it’s the same prop just from looking at a photo without taking some pretty precise measurements, either. Can you be sure it’s not a handed P-38 prop, as I originally suggested might be a possibility?
