Why do engine doesn't react on throttle,but still works after long spin and what I have to do in order to manage this situation?I have notice this on La-7 and Plikarpov.
Yes Polikarpov does not spin but this event occur when flying upside down?

I-16 (and Hurricane I, I-153) has a carburettor that floods and kills the engine when you fly upside down or push forward too hard on the joystick. Don't get into negative G situations and it wont give you any trouble. If you need to dive suddenly, roll and pull the joystick, don't push it. If you need to roll, do a barrell roll rather than an aileron roll to maintain postive G.


I also suggest a different user name. That one is bound to cause trouble.

Tully,

I-16 (and Hurricane I, I-153) have carburator

How about the other Hurricanes in IL3FB ?

the other hurricanes are fine. But they are all slow as dirt, so I try to stay away from them (especially the IIc? with its four 20mm. Those things are DANGEROUS! . . . when they can catch you.)

The other Hurri's are also carburetted, but a more sophisticaed version that continues to work while in neg-G flight.

Actually the merlins in the early hurricanes should not have had negative G problems it was a design fault,

Rather than fuel starvation the merlins actually suffered a FLOODING problem under negative G


The problem was solvedby a female engineer 'Mrs 'Tilly' Shilling' visiting Rolls. The problem came up and she looked at the fuel system drawings and noticed that the twin fuel pump system were each capable of meeting engine demands plus 20% individually if one pump failed. Tilly deduced that if the float needle was not controlling the jettingsystem ( due to negative G), both pumps could suddenly put a large excess of fuel though the system.

She immediately suggested 'a restrictor valve' should be put into the fuel line before the carburetor, which consisted of a washer with a hole in it the size of which restricted flow to just above maximum engine demand. - It
worked and was used until Rolls designed the negative G carb.

The washer became ever known by Rolls engineers as 'MRS SHILLING'S ORIFICE'

I've been having the same problem with I-16 myself - 10x for the answer./i/smilies/16x16_smiley-happy.gif

Another thing: Is there any way of reviving the engine afterwards? I think I pulled it off once, but I don't know how (possibly something to do with turning the engine off and/or engaging the autopilot? - I was just hitting all the keys)

I'm sorry if I'm asking a stupid question - I'm just a newbie...

Apparently if you switch on the Autopilot briefly it will restart, but I haven't tried it myself (haven't pushed enough negative G to stall the engine yet /i/smilies/16x16_smiley-wink.gif )

Don't quite know what to make of this, LOL-. Galway humour? apocryphal story? English humour?

hehe- ciao

If you manage to land your I-16 near a friendly base without your engine running, you can restart it. This is because in real life the I-16 required a ground crew to start the engine.

If you are not too low you can engage autopilot (in the I-16 at least). If too low autopilot will make a wheels-up landing instead. I've read somewhere in this forum that it's possible to fiddle with the mag's while in a dive. Selecting mag 1 and hitting "I" will sometimes restart engine.
