Exhaust Pipe of UH-1H

[Devrim]

Hi Belsimtek.

 

While you were developing UH-1H, when first screenshots published, at first sight I noticed the exhaust pipe's shape (or existence) on this model of Huey. Then I realized that UH-1H model didn't match with the one in my memory. I've just googled the pictures of UH-1H. I've seen some UH-1H models without that pipe. Are they another model of UH-1H or images with wrong information something?

 

Some photos:

 

 

 

So far, everything is fine, perfect actually. But I have still issues only with "exhaust pipe". :) Well; If I push my luck, I'd dare to ask that question: Have I any possibility and ability to remove that pipe as a user? :) A mod or edit any file? I know this is a stupid suggestion, 'cause I have some knowledge about DCS file system. But as I said, I'm pushing my luck...

:music_whistling:

 

Thank you.

-you can see both types of the exhaust

 

IMHO that shaped pipe prevents those hot turbine flaps from being seen by IR sensors of ground-air missiles. I think that it is designed as removable accesory.

 

...and it reduces tail boom polution :D

...I think that it is designed as removable accesory...

Let's remove it, all together! :)

...and it reduces tail boom polution :D

and let ground crew clean it. :D

It sends heated exhaust fumes through the rotors wich quickly spreads it, greatly reducing ir signature.

IMHO a good thing while flying around in your average dcs threat enviroment.

It's actually quite funny, the up-turned exhaust supposed to be an interim solution to the new threat of Striela and Striela-2, and after decades of study, research and development... many helicopters are getting up-turned exhausts now - the AH-64, MH-60, OH-58.

 

The biggest effect of this exhaust duct is the limited amount of exhaust gases interacting with the tail boom - heating it up.

 

 

There are better designs available today though, like the DAVIS CBT (not up-turned).

I have to admit, I don't like the exhaust we got very much. It's just not quite that Huey look I have in my mind when I think about that bird.

You would rather be an easier target for IR threats :smilewink:

Belsimtek's Uh-1H depicts an 80's bird or close to that. The iconic picture you have in mind is some 15 years older.

And then there's hollywood...

 

That being said, i think we all share that iconic vietnam picture in our head and i do hope that when a vietnam theatre gets released there will be changes to the huey to make it fit in.

 

Oh, and a -B or -C of course because D/H variants weren't really gunships way back when. Though i fear that this is an unlikely thing to happen.

Hell yea! lol

[WolfK33]

I'm getting shot down anyways, so I'd rather die looking good :smilewink:

 

Yes Vietnam era birds in different variants and the fitting theatre would be a dream !

Our german Bundeswehr birds don't have that exhaust pipe, to be honest, the first time I've seen that thing is in this sim :)

[Derk]

The bundeswehr huey's are in fact licensed build Uh-1D's by Dornier. They differ even more from your typical huey than belsimtek's model in some ways. ;)

 

+1 for Bundeswehr camouflage though, always loved it. Much cooler than our dutch helicopters.

[Sundowner.pl]

No, Dornier's Hueys ar license build UH-1H, the D on the end of designation was a German idea, don't know if it suppose to mean Deutchland, or Dornier, but it confuses the hell out of people ! :P

[Derk]

indeed it does!

 

I stand corrected, thanks Sundowner.

Now a bit on the up-turned exhaust, and why it's not present on many helicopters.

 

Every piece of technology has its drawbacks. If we take the exhaust gases and start to direct them somewhere off the turbine axis, or start mixing it with outside air, there is a pressure buildup aft of the engine power turbine, this in effect create two problems: 1 - reduces power; 2 - increases temperature - this poses additional performance limits, and shortens component lifespan. The whole setup also weight a bit more than usual.

 

So now if we take a look at the German Hueys - those are utility helicopters, that are not deployed for combat, but also work as Search And Rescue platforms, and training for mountain flying in the Alps... Those are roles where you need lighter aircraft, more power, longer life - so no IR protection kit.

[ebabil]

yeah , rear faced shape way too better

[FZG_Immel]

I concur

[Rangi]

I guess i depends what you are used to. The Australian Hueys I grew up with had the exhaust deflectors since the mid 80s (IIRC) so that is the 'true' shape to me. They just need add the intake covers as well.....

[J7G]

Ah I always thought you were an ex-pat Kiwi...

[Rangi]

No born and bred Aussie, the nickname was given to me by a kiwi friend.....

Hopefully the final product will keep the current model with the "sugar Scoop" exhaust and cable cutters, that is my favorite version circa late 80's early 90's.

 

It would also be nice to see a scoopless version as well for those that want an earlier version of Huey.
