New startup video

[EvilBivol-1]

Nice vid Matt - well done.

[TekaTeka]

Yeah, and uploading to jabogs site failed... :(

 

Really? Then I'll try it.

[leafer]

WTF!?!?

 

After the video uploading is completed, youtube gave me a "You have not uploaded any videos yet!" message. This is the third freaking time!!!!

[TekaTeka]

Yeah, and uploading to jabogs site failed... :(

 

I've tried it, but failed too...:cry:

The file size might be too large.

[Groove]

I might be able to provide a addtional FTP. Hope its ready til tomorrow !

Leafer has youtube'd it over here:

Grate job sir, one question, Should we expect fault happen when we fly the helicopter or start the engines. For example hung start, hot start, over temp, flame out, engine stall, etc.

 

Generally the Mi-8/Mi-24 pilots' statistics shows that if TV3-117 is in order it successfully starts in 99.9% cases.

 

If you abort air starter before the engine is at idle mode you can get hung start or hot start or will see that gas generator rpm goes down to fuel shut off rpm.

Overtemp is possible if you have ice in the inlet and/or electronic governor is down. If it's OK it maintains the temperature.

Flame out is possible if the iceing is severe as a result of compressor stall. Before it you will encounter power loss and EGT rising.

If you overtemp and overrev the engine the GG turbine will suffer and its failure probability will increase.

 

These effects ARE NOT scripts. They are natural results of the physical model.

Amen to that. Sounds great Yo-Yo!

Very impressive!! You are using "organic" programation, isn't it?

[Triggerhappy69]

.. sniff.. I have watched the vid at least 5 times today, and it just brings tears to my eyes every time,... Asepcially towards the end when he sais the fixed sight looks good to..! I know how much that means for a HUD to hear that every now and then... thanx..

 

 

But seriously.. I have fallen more in love with this sim.. And that's wierd.. 'Cause I have'nt even seen it yet.. Must what those "post order bride" guys feel while waiting for her to come to him..?

 

 

 

 

 

(epilog: On a serious note I must say that whatever shape or how love comes, it is still both correct and a beutifull thing.. just so I don't step on some toes here..)

If "organic" means "physical" my answer is "yes". Starting from FC and especially in DCS we keep proceeding to model physical process dividing a system to subparts with their own charachteristics and tune them to obtain the whole system parameters fitting real. The units chiefly interchange with physical parameters not flags, scripts, etc.

That vid is a work of art (in a weird twisted, demented sense that is) Good job Wags looking forward to other "producers note's"

I wonder if the TV3-117VK used in Ka-50, also have the 5 primary modes as the TV3-117MIII that I'm familiar with. Take-off, Limited take-off, Nominal, Cruise I and Cruise II. Or is it all controlled by the FADEC-like system ? Hope we wont fly on take-off power all the time, the MIII have to be scraped after 60 minutes of operation in that mode :smilewink:

[einsena]

you know, in the old and new startup procedure video, i noticed that they always check some systems for errors. in the old startup video i noticed the demonstrator checked some of the gauges for errors, and in the new startup video Wags also checked the IDE weather it's functioning correctly or not.

 

now, other then the obvious eye candy and full system functionality that ED try to implement in DCS, are there any point in systems error checking in DCS? other then battle damage, are systems errors and damages randomized?

 

then let's say that there are some systems error, what then? what are we supposed to do when we encounter such an event? can we "call" a mechanic? i've read somewhere in this forum that the campaign supply chain are modeled, but are aircraft maintenance also modeled in DCS?

I'd like to know that too. I had a thread about wear and tear of the mechanical parts of the aircraft, unfortunately it didn't get that much attention.

That is a very good question. Is there a chance that a system wont work correctly at the start of a mission or is that system checking pure roleplaying?

Wouldn't it be an idea to have the video (and future video's) available as a torrent ? In that case the community would distribute it amongst themselves and the DCS-server wouldn't get in trouble...

[Jascha]

Great video. I can't wait to try this stuff for myself. :smilewink:

 

Does anyone know what the next "Producer's Note" will be about? And how long we will have to wait for it? (a matter of days or weeks?)

 

I'll be patient. :music_whistling:

TV3-117VMA used in Ka-50 has Takeoff (rated 2200 hp), Nominal (1700 hp) and Cruise I/II ratings. EEG of VMA does not support ratings higher than Takeoff but if you switch EEG off the engine shurely can achieve higher ratings but not for long time though...

TV3-117 (starting from early TV2, I think) historically has hydromechanical fuel governor and EEG precisely supervising the boundaries of GG rpm and EGT and protecting from PT overrev. It can works if EEG does not function.

So in BS if your EEG is down you have to watch EGT by yourself. Of course if you don't want to fly out of engines. It's up to you to choose what do you want: high power for a short time or long and safe flight. :)

[JEFX]

Thanks Wags!

 

Great Video and it surely shows how greatly modeled everything is in that cockpit!

 

I think as Einsena and MBot that the systems checks and failures should be more naturally implemented. As I understand Yo-Yo's answer, there are physical actions that the pilot can do to damage the system, for example:

 

If you abort air starter before the engine is at idle mode you can get hung start or hot start or will see that gas generator rpm goes down to fuel shut off rpm.

 

But there are other conditions that are just natural random weather conditions, for example :

 

Overtemp is possible if you have ice in the inlet and/or electronic governor is down. If it's OK it maintains the temperature.

Flame out is possible if the iceing is severe as a result of compressor stall. Before it you will encounter power loss and EGT rising.

 

If we start the mission in winter, and the temperature is set to very low in the weather engine, will it have an incidence on those factors? If we start with or without snow, will it change the danger of getting those kind of failures?

 

I think that the whole process of failures and especially the randomization of failures should be rethought profoundly. In FC the failures system is almost useless. Even with a randomization, there should be a sort of hierachy (some systems would be naturally more inclined to fail, even if randomized, than some others, and this depending on some weather conditions, for example).

 

Does that make any sense?

Startup in winter conditions shouldn't be a problem, what Yo-yo is talking there is probably about already working engine, with an deice system disabled/malfunction.

by the way, in order to get the attention of everyone and to keep the DCS site REALLY dynamical and marketingwise attractive (especially to newcomers) I think that something of such an importance should be advertised in the main pages of the Web site:

 

1) in the news page (that IS quite a bit of news!

2) in the Developper's journal

 

Now it is hidden in a way, deep within one single thread of discussion in the forum, and someone who does not come everyday to the forum would not naturally see it at first.

 

Just a thought to distribute the good news!

 

Thanks again for the video, please keep them coming!

You guys have my deepest admiration!
