I-16 neg-g carburator?

[Anaxogoras]

I'm surprised someone is not all over this with a definitive answer.  No one gives a crap about Russian aircraft, I guess.

Not sure what you mean in your last post Gava.

 I tried to answer your question,other than the M25 being metric as in fastener sizes it's a copy of the wright engine. the brewster used a G5 version{i think} the sbd,f4f,etc.have versions of the wright.So unless you can show that the solex carb. is not equiped to handle neg G's I'd bet it's modeled correct.

Hi Morfiend,

There seem to have been at least 4 different engines that powered the I-16, and even if some were a copy of an American design that did not cut out under negative g-force, do we really know if these copies were of the same quality?  I'm also willing to give the benefit of the doubt to a Russian flight sim when they model the I-16 with negative-g cutout, unless I see something compelling that contradicts it, but that still doesn't mean I have knowledge.  Usually we want to see a primary, or at least a secondary, source to answer these kinds of questions.

Hey Gava 


 Well you wouldnt want to hear my oppinion of that "other" sim/game.

 Benefit of doubt,not from me!Oleg and his game may have nice eye candy but thats all I have good to say.

 I'll leave it at that been enough drama around here lately.

leave the i-16 motor as it is. its slow enough alresdy

[Anaxogoras]

Right.  HTC should fix the negative G cutout on the Spit and Hurri Mk I because they are also slow.

[Krusty]

IL2 is not a source of anything reliable. It's 100% subjective in its modeling of all aspects from flight, to departure, to weaponry ballistics to damage model.

Nothing about the game seems historic, IMO. I wouldn't go starting debates based off of what they do in their game, because chances are it's not related to historic fact.

Regarding Neg Gee cutout.

.........Essentially if it used a float type carburettor you've got that problem, if it used a pressurised fuel bowl (vacuum drawn carb) and the fuel pump was strong enough you haven't........................


However, you can get things like a rebuilt Zero, where stock parts were replaced by what was handy. So  the original zero did not have Neg Gee cutout, but the rebuilt one in the Allies hands DID have it because of not enough capacity in the replacement pump.

It all depends on the specifics of carb, fuel pump, and setup.

You want it changed, you provide the proof.

Agree

Slow down there.  Where did I ask for it to be changed?  You're putting words in my mouth.  All I've asked is if anyone has evidence either way, and so far we've got a big fat zero on either side.

[Ghosth]

Funny, do you see your name in my post? Cause I don't.

I'm not putting words in your mouth. I didn't even tell you specificly to put up or shut up.

I just said "You want it changed, you provide the proof"

Overreacting perhaps just a little?

More like " guilty conscience".

[Anaxogoras]

My bad then.  You know how often people interpret you in the worst possible way at this forum?  My over-reaction shouldn't seem so surprising.

While this is not definitive, I believe that the I-16's carburetor was probably pressurized.

Given that the M-62 was based on a licensed Curtiss R-1820, looking at the carburetor spreadsheet from the Aircraft Engine Historical Society (see link below) it looks like all R1820's had pressurized Stromberg's. There's still a lot of stuff I need to read through but, so far everything is pointing to the originally licensed engine having a pressurized carburetor.

Hey Baum

 I'd read that and the only problem I found was that while the wright had a stromberg the M25/62 et al.use solex carbs.This we discussed already,it's been difficult to find much imfo on this carb and I'm abit leary of entering some of the russian sites to find anymore about it!

 I wonder,since the engine was a copy,would solex have simply copied the stromberg?

  Then there's the M22 version,which used a Bristol design copy,I wonder if thats were the carb problem comes from,I've been too busy to research any of that yet.IIRC the first batch of I16's had the M22 as the wright copies were going through teething problems.

 Funny how a simple question leads me off to research and waste my time,but licky for me I still have plenty of time.......Live &Learn....
