F7F Tigercat SOH Project

You're welcome Milton, I think it's awesome that you guys work so hard on these things. I'm glad to see there are a lot of air tanker buffs here as well. SOH is a great place.

Anyone interested in seeing photos of air tankers in action, you can check out my website. That's my side business. I shoot wildland firefighting aircraft in action. www.airattackimages.com. In particular check out the USFS tab and Cal Fire aircraft tab.

Slund is correct on everything he said. I didn't think modeling such advanced details would be possible, but yes... the retardant typically is placed right up against the active flame front and you'll usually see the fire affected by the dusting (mist) from the retardant falling next to it... Steam, reduced flame lengths/intensity, etc. Retardant is generally dropped right next to the advancing fire except in cases where the fire is moving too quickly.

--For instance the La Brea Fire last season in Southern California was moving so fast at one point, and had such expansive lines being drawn around it, that the tankers were dropping 1/4 mile ahead of the flames. Like Slund alluded to, tactics like that are used in cases where the fire is going to get around the retardant before following tankers are able to arrive and tie into the line.

I don't want to get this subject off the topic, which is of course the awesome F7F project. But this seems like a good group of people for me to ask this question around. It sounds like Slund has some good fire scenery that I'd love to check out if he shares it, but I was wondering if it was possible to have a fire scenery in FSX, even if it was very simple and didn't have flame -- that had a gigantic pyrocumulus header (smoke plume) that wouldn't move or disappear the way clouds do in the sim. Something that actually rose off the ground and looked correct to depict a huge column of smoke. Like I said even if it had no flame, at least it would give us something to fly to and return from. If it's possible to tweak the weather features in the game to do this, it would also be great because you could get the idea of what it's like to fly through the smokey skies on the fringes of the fire. I'm envisioning the Station Fire burning in the Angeles National Forest and being able to fly the 60 miles to and from Fox Field while seeing this gigantic smoke column rising 30,000 feet into the air in front of you.
 
The F7F-1 is currently undergoing spin testing. It will be placarded, do not intentionally spin. I have in test recovered from a twenty turn spin, but there's no guarentee, ya might make a smoking hole in the ground....

I reckon it depends on your altitude...lol!!:pop4:

REtardand content or weight

Hi Again

I read through the thread,maybe over read it,but what was the retardand content or weight of the F7F Tanker ?

Still I need a drop rate of the retardand-->anything/min or sec

Thanks for help

Getting on board

Some time ago I received a message from Roland (thunder100) regarding the use of a red retardant drop effect that I had developed, that was hosted on Shawn Lund's site.
I have discussed with Roland, via email, the requirements for the retardant effect, and have started working on the effect now. I should be able to post a few screens within the next week.:salute:
If anyone has any ideas about the appearance of the effect, feedback is most certainly welcome. I am unable to write any gauges to control the release of the effect, but i understand that someone else has this covered.
However, any reference material, especially quality videos of retardant releases, or those showing the retardant hitting the terrain would be greatly appreciated.

Thanks for getting me involved in this project.

Thank you for jumping in; we greatly appreciate that. :applause:
 
The speed at which a tank of retardant is emptied will vary, it depends on the type and quantity of the drop. For example, with a 12 door tank the Air Attack officer has the option to ask for a single door, 2 doors, 4 doors, 6 doors as a salvo (all at one time) or they can ask for a string drop of single doors, double doors etc with a specific interval between door openings. It probable takes a single door less than 1 second to completely exit the tank, a single door string for a total of 12 with a half second interval would take 7-8 seconds to exit the tank. It's similar with a constant flow tank, you ask for a certain percentage of the tank plus a coverage level. You can drop all at max (the entire contents of the tank with as wide a door opening as the tank system will allow or at the opposite end of the scale, all at coverage level 0.5. An Electra tank could probably lay a 5000 foot line using coverage level 0.5, I'm only guessing but it would probably take 20 seconds to empty the tank at this coverage level. I'll take a few pics of the various bomb tank controller and try and write up a bit of an explanation of how each works if that will help you Roland?

Here's the controller for a 12 door tank mounted on an Airspray Electra.

Would be great and still pls a hint how much content(liter,lbs,whatever )retardant the F7F has had

If I reflect above I would drop 1/2 of content(2 doors) twice or 1 time all (4 doors)-->true?

Thanks

Roland

From what I've managed to dig up they had 800 gallon capacity tanks, but only flew with 700 gallons due to safety concerns. According to Phos-Chek a company that makes fire retardant for out here says that there D75 (fixed wing / high viscosity retardant) retardant weighs 8.91lbs. per gallon mixed and loaded.

700 gallons sounds about right.

If it was a 4 door tank you could drop single doors, double doors or all 4 doors at once, (the two and four door drops would be called salvo drops, ie, 2 door salvo, 4 door salvo. Single door string drops could be for a total of 2, 3 or 4 doors. A double door (2 at once) string drops could only be all 4 doors, ie a double door string for a total of 4... (two doors open, then after a set amount of time (0.5 seconds is standard) the other two doors would open) The retardant coverage on the string drops is varied by adjusting the time interval between the doors opening. It's not as complicated as I'm making it sound...
 
Thanks a lot

We have now all data we need (More of them) now we have to learn FS to do such things

@Slund

Would you have a drop panel picture like the Electra for the F7F or one from an 4 door/tanks plane?
This as following recent mail the we drop all at once version is not so realistic

Thanks a lot

Roland
 
We don't have any four door tanks left in our fleet, the Firecat group has been replaced by a Airtractor 802 group with constant flow tanks. I'll see what I can do about getting a photo of the Firecat controller, it just might take a few days.
 
Can't Wait

Hey Milton,
Your team puts together the nicest aircraft. I have really enjoyed all of them. The F7F will be my next favorite to the A-26.
Speaking of the A-26, I can't find the link to Real Old Salts version Super 26. I must have lost it moving from one puter to another. If you or anyone could lead me in the right direction I would reall appreciate it...
