I have a question why the spits engine doesn't stop in a dive it was a well known fact because of the merlin carburator engine in a dive the engine stoped or started to stop ? can anyone make it that way because that was the bf-109 rescue from the spitfire and here there isn't any S! guys
If you wonder i have noting aganst spits exept when they are at my tail.

I think that was only a problem in the early Spits and Hurricanes.

AFAIK, the negative-G problem only existed in the early model Spitfire MkIa. This version of the Spit is not modeled in IL-2...I'm afraid you're going to have to find another way to get them off your six :wink: 8)

A mirror would be nice :wink:

One of the great problems as discerned by pilots was the tendency for the carburetted engine to cut out under negative 'G'. Luftwaffe pilots learned to escape by simply pushing the nose of their aircraft down into a dive, as their fuel- injected engines did not cut out under these circumstances.

By 1941 Miss Tilly Shilling in Farnborough had developed a partial cure for the problem. A diaphragm across the float chambers with a calibrated hole (the infamous Miss Shilling's orifice) hock: allowed negative 'g' manoeuvres, and was fitted as standard from March 1941. Sustained zero 'g' manoeuvres were not sorted out until somewhat later. In 1942 an anti-g version of the SU carburettor was fitted to single and two-stage Merlins.

In this game our Mk.VB uses correctly the last one. :wink:

oh ok then.

[Faucon]

We can't overheat on Spitfire MkIX, or it's very hard.
It is possible to change it?

[Trooper117]

I was just flying a MkIX mission this morning, and mine was overheating during combat.. So..??

[GentleKiller]

we dont want to overheat it gently. if you want to do that just keep on climbing at 170kph then you engine will overheat :wink:

[Faucon]

Well, with my IL2, it's very very harder to overheat in MkIX, really not the same in Spit MkV, P51, Fw190, Yak, ... every planes.

[Trooper117]

Mmm.. could be a more efficient cooling system.. However, with other aircraft I rarely get overheating, Unless in a combat scenario, and then, so does the Mk IX.
correct engine management is the order of the day!

[Faucon]

Well I havnt got the same IL2. With mine, I can fight at full power during 5min without overheat in Spit MkIX. Impossible to do that with other planes.

[Faucon]

I made some tests. Spitfire MkIX engine is not so cold. Dont have time to test more planes, then I dont want. So let's say I was wrong

Here my tests: Flying time without overheat at full power, radiators open and low altitude:
SpitfireMkIX: 7:00
Yak3: 6:30
P51D: 4:00
Fw190A9: 4:40

nah it's possible, I notice a lot of people changing power and stuff whilst dogfighting. I always use full partly because i'm on keyboard and not joystick. The Spitfire will overheat just like other planes, but because of the automatic system it cools better and more efficiently than manual cooling! Quite a lot of the time you see the radiator completely open. Flying at fast speed also keeps it cool but they still do overheat as I have seen during Air Races after around 5 mins it will start overheating unless you keep it at quite good speed!

I don't think you can make radiator control Manual so with the Spitfire MkIX that 7 minute is inaccurate it would actually be shorter because the radiator automatically opens.

[Trooper117]

Ok.. This might help. From the MkIX manual..

Extract from..
Engine Coolant system--- On all Mk IX aircraft the radiator flaps are fully automatic and are designed to open at a coolant temperature of 115 degrees C. There is no manual control. A pushbutton (41) for testing the radiator flaps is on the electrical panel..

Extract from..
Operating data---
Max climbing (1 hour limit).. R.p.m. 2,850.. Boost. +12.. Coolant temp. 125C... Oil. 90C.
Max continuous.................... R.p.m. 2,650.. Boost. +7... Coolant temp. 105C, (115) for short periods.. Oil.. 90C.
Combat, 5 mins. Limit........ R.p.m. 3,000.. Boost. +18.. (+15 on Merlin 61). Coolant temp. 135C... Oil. 105C.

Note.. Combat, full power for 5 mins max!! This sounds about right in game to me?
