View Full Version : Anyone Know the Jet Trick?

Ok, we all know that WWII era jets tended to have less than reliable engines. They also tend to catch fire at inopportune moments, like a scramble. Here is a trick I found that you may or may not know to allow quick takeoff of any jet in the IL-2 series.

1.Quickly turn on both engines (be fast if Seperate Engine Start is enabled).

2.While the engines are starting use your throttle (I have only confirmed this on a joystick slider) and advance the throttle all the way to 100 percent, you have to change the throttle after you start the engine in order for this to work.

3.Hold the brakes and wait for the engines to fire and spool up.


You now just need to rudder in the correct direction to steer the plane in a clear path for takeoff. Not sure if this is intentional on the part of designers or an oversight, but it works wonders.

I can do that in 1.22. It's a bug. Post it on ORR.

hehe yes i did it from the beginning with FB v1.0? yes its a bug and no one complained about it,its a very handy trick if you want to scramble oh and you can just ignore the overheat message you get within a few seconds
just go over 600 and the message dissapears

Yea I posted this a while back ;-).
KSS_TOPGUN_UK told me about it not long after FB.

I ignore the overheat messages always anyway.http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

The Overheat thing is cos ur at full power with low speed and the engines (Me262) were air cooled.

Me-262's Jumos were single shaft, single flow, jets. So...
You refering to them as being "air cooled" implies that they are cooled by the air flowing ON THE EXTERIOR of the engines gondolas (the air which runs into intakes is more or less used as comburant, but for sure it exits at very high temperature, some of which is atained very close to the entrance)...thus, U ARE WRONG MATE...

To be right it would mean that we can called any car engine as air cooled as air flows around them in the engine bays http://ubbxforums.ubi.com/images/smiley/53.gif

Are dreptate sobolane http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif parte din aerul comprimat de prima jumatate a compresorului ocoleste camerele de ardere - trece printr-un bypass ca sa raceasca camerele de ardere si partea exterioara a palelor turbinei (care sunt gaurite special pentru racire). Pe deasupra nu are nici un fel de sistem de racire a uleiului, pur si simplu uleiul nu are nevoie de racire speciala. E corect sa spui ca Jumo 004 e racit cu aer. Misto masinarie, super simpla, super ieftina.

Well, all engines are air cooled in the sense that airflow is required in order for the water/oil radiators to work. This is why most automotive engines have a tendency to overheat if you drive around at low speed with high revs for too long (i.e. in a traffic jam), and are often equipped with fans to cope with those situations.

I don't know why there is a speed/cooling relationship on the 262; the engine housing would act as a radiator, but the combustion chamber would still be exposed to the same temperatures. The 262s quibbles are more to do with poor metallurgy than inadequate cooling; the overheats should happen when you use full power for too long (regardless of speed and alt).

If there is cooling liquid running inside the engine we call the engine liquid cooled. It's true that the liquid itself is air cooled, but using liquid for cooling makes the engine very different than those that do not use. We clasify them using this simple criteria.

Yes there was a speed/cooling relationship on the 262. After the first 4 compressor stages part of the air follows a bypass in compressor wall, and cools the combustion chambers and the turbine blades which are hollow in order to allow air cooling. Also compared to other engines Jumos did not have oil cooling simply because they did not need it - the frictions were small, all the compressor stages and the turbine were on the same shaft, only shaft bearings (and some accessories) produced friction.

Anyway, I also have noticed that, even acting normally, the message "Engine overheat" that you have on the Me.262 just disappears as soon as you take-off and gain enough speed to get a sufficient airflow in the jet engines... and this sounds quite normal...

I'm with Buzz here on this one. However I do/have flown jets a bit since Aces release. (just need to know what I'm up against)

Still can't see the bypass.
