Title: Jet Engine Exhaust Flames
Post by: shotgunneeley on May 13, 2010, 12:40:35 AM
Plane and simple, can we get some exhaust flames on the jet birds? Currently there is just a black hole on the ME-262, ME-163 and AR-234 engine exhausts. Maybe since the 163 relied on rocket propulsion it could trail a bit of smoke.

     Jets usually only flame on startup and shut down, you really down want the flames burning past your turbine
section in regular flight.  Maybe that's one reason for those tiny TBOs for the jumo engines come to think of it  :D

Yeah but shouldn't we at least see the glow of the heat coming from the engines? A tremendous amount of heat and energy is coming out of those engines, it shouldn't be just a black hole.

      Usually what you see is a little shimmer caused by the hot air.  I spent about 25 years working around jets on
a flightline ramp and it was amazing how easy to was to get caught off guard by exhaust if you weren't paying
attention.

As Rino said, combustion will be contained within the combustion chamber. The only time you'll see flames from the engine is during a compressor stall generating a rich burnout (rich burnouts were quite common during the starting phases, too).

It would be cool if they trailed a little distortion in the air from the exhaust heat though.  That would be a pretty neat effect in game I think.

That would probably cause a significant performance decrease...but still, it would be cool :)

Thats debatable. Depends on how you model the texture. In IL2, the ripples are visible, yet appear to have little to no impact on performance.

Hundreds of people flying at the same time much on IL-2?

What would be nice is flames licking the cowling of my Mustang on startup, and Blue flames funneling outta my 190 when the supercharger kicks in :D

Actually, you don't meet hundreds of people in AH neither. How often do you see "hundreds" of planes within your 6.0k visible range? Probably around 50~60 planes max provided there's a hefty furball formed... and even in those cases the most friendlies/enemies you'd have within 3.0k where details start to show, would be not more than 20~30. Besides, the detail depiction range can always be altered as an option. Some may be able to see it only when up really close, others might want to crank the detail level up and see such details from further distances.

The thing is, by today's standards, depicting stuff like glows, waters, distortion and etc etc.. ain't exactly state-of-the-art gfx tech. It's quite amazing how fast the industry advances... just a few years ago, seeing water that looks like water was quite amazing in Silent Hunter3... nowadays, even MMORPG games have kewl looking reflective water...

Option to enable or disable it. Done!
So us people with good systems can enjoy things we want and it gives the guys with not so great systems some initiative to get a new computer. :P

+1 to the shimmer effect with the ability to disable if there is a performance drop involved.

Been asking for heat waves and vapor trails for a long time. +2 :aok

Only when the afterburner is engaged, and then only (really) at night.  You can see a burner in daylight but you have to look for it (unless you're looking at the tail end, which is good if you're flying and bad if you're on the ground).

The back end of a jet engine looks suspiciously like a black hole most of the time.

All of which is moot; the Jumo wasn't augmented.

By the way, smoke is also bad; the J59 had far too much of it, as did the TF-30.  The good news with the -30 is if it was smoking it was probably working.  In the immortal words of Joe if it says Prat & Whitney on the engines it better say Martin Baker on the seats...

Simple. Model the texture to show it only on your aircraft, not the other jets in game. On another note, when would you ever see "hundreds" of jets buzzing around you in the MAs? Youll rarely see more than 4 in a sector on most days. A graphical implementation wouldnt be so far fetched as you might think.

Not so much the 'hundreds' of jets in the MA's as it is a comparison of AH's massive multiplayerisming vs. IL-2's maybe you can get 15 people in a hosted room.

LOL, GE engines FTW!

     The F4s I worked had "low smoke" J79s...I'd hate to think what the "high smoke" ones looked like.  :D
In fact it was kind of cool watching the birds at the end of the runway.   When the smoke disappeared, you
got ready for the burners and the start of the rollout.
