Anyone going? I'll be there again this year..

That's sexy.. Too bad they don't have a Dora competing.
-
I don't think they had any german aircraft there last year that I remember.. A few Russian (yaks), but the majority were either American or British..
-
Yep... Too bad none of those multimillionaires want to spend their allowance on a Luftwaffe intruder...
-
There's probably just too few of them to be used for racing or modified in any way like the majority of the racers at Reno..
-
Haha.. I doubt there's such a thing as "too few" to empassioned millionaire gearheads.
-
Well I meant maybe there's too few German aircraft to be used for racing like this? I'm not sure really, but these planes are pushing 500mph+.. I don't see too many 109's or 190's doing that without some serious modifications..
There are other classes where the planes aren't modified though, but racing is quite dangerous.. 3 people were killed last year due to crashes, so maybe people with the German planes don't want to risk it.. Who knows..
-
You know there's no rule that says you have to use an old warbird in the Unlimiteds. Frankly I get tired of the constant attrition. I liked the idea of Rutan's Pond Racer, though it couldn't resist overheating at every opportunity.

It's a shame she crashed.. :(
That was one beautiful aircraft..

Yep I understand and agree.. somewhat. I just think it has to be tempting. I think the 190D ought to make for a good racer base.
-
I'd love to see a Dora too, but I don't think it'll ever happen. Do you know if anyone's racing an LA-7 ?
-
There are a few Yaks that race, but I dont think there's any LA's.. Here are some pics..
Czech Mate - A modified Yak-11 (The sickest sounding plane at the races hands down.. The plane is small in comparison to the rest but it sounds like a monster)

i think dago red has the record right now, with a single lap speed of 512mph, and an average qualifying speed of 507. not sure, but i think that she's the only pisotn engined unlimited racer in the 500 range right now?
as for german aircraft, there aren't any FW's flying right now, are there? and i think less than a dozen 109's?
i had read somewhere, about the modfications to the dago red. they were very very extensive, and millions of dollars.
i'm kind of doubtful that someone would take a one of a kind aircraft, and modify it like they'd need to for it to compete.
-
I think Rare Bear and September Fury have been 500+ or very very close..
I was disappointed that Dago Red wasnt at the races last year, but it will this year.. :aok

A lot of my squaddies are planning on attending. <T.S.M.> ; The Screaming Meanies. Mars, LuckTSM, verbal, and others are all great guys and I'm sure you could meet them for a beer or something.
-
Wow, I thought Czech Mate was really closely cowled till I saw this view of September Fury. Really gotta wonder how they keep this beast from melting. Do any of these guys use evaporative cooling?

Most of the unlimiteds have ADI systems to keep them cool..
"ADI stands for anti detonation injection. ADI serves two primary purposes; firstly it reduces the charge temperature, via evaporation, as it is sprayed into the intake system. A lower charge temperature increases the density of the charge and reduces the onset of detonation. Secondly, once ADI enters the combustion chamber, it reduces the flame front temperature, again delaying the onset of detonation. ADI fluid is introduced at the intake elbow, colloquially referred to as the Horse's bellybutton because that's what it looks like..!!! ADI fluid is made up of a 50/50 mix of distilled water and ethanol or methanol. Engines with the aftercooler removed are referred to as 'tube engines.' by the racers."

This article is a very cool read for the gearheads out there.. :aok

Water injection has been around a long time as a method to preclude detonation and allow higher boost, but it's not the primary cooling mechanism for the engine is it?
-
No, it isn't. They're still cooled the way they were when they were built, for the most part. Some are water cooled, some air cooled.

Hence my original question. Look how closely cowled this monster is. Aren't you guys a little surprised they can get sufficient airflow to that big radial to do the job? These things run 3000+ rpm @ insane boost.
-
They also have oil cooling spraybars that spray water directly over the oil cooler.. See the left wing on September Pops..

Its on both wings for Dreadnought, but you can see it bottom left of this pic..

That's why the engines blow up. Cooling is sacrificed for speed. So is reliability. More so than most motorsports, with the exception of maybe Top Fuel and Funny Car in drag racing.

Thanks, that's what I expected. I knew that TF & Funny Cars had no cooling systems per se. In the good old days, they could have just mounted a spray bar ahead of the cylinders and sprayed R-12 during the course of the race. You'd still need sufficient airflow to evacuate the engine compartment though.

Thats average speed over the 8 mile course.. In a straight line these planes do over 500mph..
Rare Bear had an average lap of 495mph in 2003.. Check the records page.. :D

Ist place in 07...holds a few records for prop driven aircraft..to wit: " Closed Course World Speed Record (528.3 mph) and 3000 Meter Time-To-Climb Record (91.9 seconds). :D
