Hot Rod Job For SpaceShipOne
rwven writes "MSNBC is reporting that the engine on SpaceShipOne has been modified to provide more thrust, for a longer amount of time. Mainly, the Nitrous Oxide tank has increased in size to lengthen the amount of time before the dropoff of thrust when it goes from a liquid to a gas. Also reporting is Space.com."

Sounds like the 12'o clock Double Fiesta Burrito Platter
In related news the name of the project has been changed to RiceRocketOne.
Next up: Spoiler, racing stripes and a window decal that says "Outta Space!".
The racing stripes alone decrease wind resistance by 17% you know.
Using just a nitrous oxide charger and a balloon, I was never higher than low Earth orbit. But with a 60L tank, a garbage bag, and a mattress to jump on, I achieved full astral projection, even interdimensional travel! I recommend a complete crew of 1 extra spotter breathing 21:78:1 O2:N2:Ar2, for a safe return voyage. YMMV.

It kinda looks like one with wings too.
Even so, I can't wait till I can go for vacation on the moon. Now THAT would be getting away from it all.

SpaceShipOne has been modified to provide more thrust, for a longer amount of time.
-Need engineer 24/7 willing to travel to repair the engine.
-Pay rate $14 an hour US dollars. Contract to perm.
-Will be reporting to 6 managers globally.
-Time and a half pay on holidays.
-No visas excepted.

They've got a big tank of nitrous oxide and they're using it as rocket fuel? Priorities here, people!
WWJD for a Klondike Bar?
Nitrous, eh? I give it 15 years, tops, before all the ricers start to get their hands on these and put ground effects and body kits on all of them.
On the plus side, if they crash them while driving like idiots they'll be even more likely to kill themselves.
I love evolution.
"Mainly, the Nitrous Oxide tank has increased in size to lengthen the amount of time before the dropoff of thrust when it goes from a liquid to a gas."
So they'll be laughing themselves all the way into orbit? never know when you might need that extra 20% buzz...

they just for decoration man, just for decoration!
Look at the cutaway - it really is a "hot rod." It appears the n2o tank is, like, six feet in diameter and right behind the crew with the engine right behind that. Yeesh, it's almost like one of those jet powered dragsters with wings - and some brave soul is gonna take it into space? I guess the next evolution will be nothing more than a good flight suit, an engine, and some carbon fiber bungee cords...

It's used for the same reason they're using it in the spacecraft, to add extra oxygen to the combustion process. More complete burn = more power.
I hope the Discovery Channel picks this up next season...

Senior says that we have to have this spaceship ready for the X-Prize in November, but I just don't see it happening. We're just halfway through the mock-up and the combustion chamber has to be at the chromers by tomorrow.

Whenever we do a theme spaceship, we always run into some problem. Like with this one, the attitude control thrusters were too close to the sissy bar. But Cody came through when he reversed the polarity of the positronic matrix and reconfigured the EPS conduits to emit tachyons through the deflector shields.

I really had my doubts about this spaceship, but Justin came through in the end. He did a killer job on the tins and the flames and pinstripes on the body really make the design work.

" Can somebody tell me what nitrous oxide does in a car engine? It's not a flammable gas, is it?"
In a word, oxygen - nitrous contains more oxygen than air and is in a highly dense liquid form. In a car engine, nitrous, along with additional fuel is squirted into the intake. In the hybrid rocket engine, a large cylinder of rubber is the fuel; the nitrous is the oxidizer.
Chaos maximizes locally around me.
A lowrider is meant to look good and to move slowly so that everyone can see how good it looks.
A lowrider is the antithesis of a hot rod.

Usually nitrous oxide systems are set up to inject extra fuel along with the nitrous oxide to keep the correct fuel/oxygen ratio.
As an aside, F&F fans should realize that NOS (Nawz) is the logo of Nitrous Oxide Systems, not a chemical abreviation for nitrious oxide, although they spend a lot of money trying to get their name associated with it.
That's right, we're powered by the online casino goldenpalace.com.

Thats what she said , Whooooo !
Nitrous used as a drug has been mentioned a lot, so I want to point out that only fire can use this oxygen. To your body, nitrous has no usable oxygen. If you breathe it in pure for too long with no outside source of oxygen, you will pass out/die.
The oxygen component actually provides only a small part of the power increase. NO2 has an extremely high latent heat of vapourisation - in other words it absorbs massive amounts of heat when it is injected and vapourises. This tremendous cooling effect allows a much denser cylinder charge and requires (a lot) more fuel be injected along with the NO2 to maintain the correct fuel/air ratio.
With the Japanese section added to the station, will it be given a giant aluminum wing, huge Type R stickers, 22 inch Sprewells, and a body kit that puts it in an orbit so low, it knocks over your chimney?
What has not yet been mentioned in this /. discussion is briefly, though not directly, mentioned in the aforementioned space.com article. The changes to the engine were made at least partly to offset the previous glitch encountered during the previous flight. "...the increased liquid nitrous oxide should delay that drop off and provide more thrust earlier in the flight, when SpaceShipOne's control surfaces can still bite into the Earth's atmosphere for steering." They hope this will allow them to reach their target altitude this time (almost missed the space altitude last time) without having to resort to secondary guidance systems.
$#!^ happens, but why does it always have to happen to me???
Will it work on my Kromag?
I wonder how much testing this new engine config has received? I don't believe it has gotten any flight time- it would have to be all ground tests.
Seems kind of concerning to me. When I finish working on my car, it sure as hell might crank up and idle okay in the garage but it is usually hit or miss the first time I take it on a road test. Obviously, these guys are better rocket scientists than I am a car mechanic, but you get the point...
When I read this, one of the first rules of project management popped into my head:
I don't see things in black and white; I see the gray. Heck, I actually see in color, which makes things more difficult
The N2O disassociates into nitrogen and oxygen at combustion chamber temperatures, and the oxygen allows additional fuel to be burned, producing the horsepower increase. The nitrogen content acts as a "detonation buffer", preventing preignition of the mixture from the increased chamber pressures/temperature.
The other thing that nitrous does is to act as a "chemical intercooler" when injected into the intake manifold. When the liquified gas flashes into a vapor, it absorbs large amounts of heat, cooling the intake charge and increasing it's density.

Modifications in design invalidate the hardware test, and put it up there in the "risky" category again... esp. with the modification being an increase in the amount of fuel hangin' around. I hope they had this intent in the first phase (we start with this size tank, and move up to this one later)...

So it's not yet SpaceShipTwo.
SpaceShip1.2, perhaps?

My Spaceship topped out at mach 3 this morning.
DaVinci's first flight is set for two or three days after SpaceShipOne's first flight. It'll all hinge on turn-around time, provided both first flights are successful.
Scaled Composites says they're looking at a potential 5 day Turn-around if everything goes smoothly.
If you say or type nawz you sound like a dumbass. Real racers say nitrous, unless they say "giggle gas" or some other even weirder version.
It sound like you know what you are doing... But it's N2O, not NO2.
Since when does Argon bind to anything?
Or do you live in an alternate universe after your NO2 experience.
Just say N2O drugs... Wait....

nitrous contains more oxygen than air
Compared to liquid oxygen though, they should be pretty similar in oxygen content. The the reason nitrous oxide is used rather than liquid oxygen is that when NO2 is used as an oxidiser, the nitrogen atom that is evolved releases a large burst of energy when it forms N2. Ie:
2 N02 => N2 + 2O2 + energy.
The following is a link explaining the energy difference between an N-O bond and an N-N bond. Simple nitrogen chemistry
HTF can something be redundant when no one else posted anything like it?! Oh, wait, this is Slashdot, where being on crack guarantees you mod points. Except for me. I'm not on crack and still get mod points all the time, and I use them to reward the intelligent and punish the foolish. M2 is also a very good weapon for that (note that these are not defined in terms of "agrees with me" and "doesn't agree with me." I have often modded up people with whom I vehemently disagreed b/c they presented a cogent and well-formed argument, even if I did not share their opinion and/or conclusions).
All crack-crazed mods, be forewarned that I M2 daily and have been doing so for years. I mark ALL Redundant mods unfair as a matter of policy. If you care what happens to your moderations in M2, *do not* mod anything Redundant. I will get you. You may, however, mod this as a troll, although I'm not trolling you. I'm completely serious.
This isn't really about the moderation, it's about the fact that some people are clearly too stupid to have mod points and yet get them anyway. OK, you can mod that flamebait if you like.
P.S. I know I'll get modded down for this, but...
