O.T. RAW POWER AT ITS FINEST

Wasn't this posted in aus.cars only the other week? And nearly every point ripped to shreds in less time than it takes
the wheels of a dragster to turn twice?

I dunno Danien, I don't read aus.cages. I got it as an email from a mate.

ok so it uses a rocket, but its still fast.

hehe. Yep.

 

44 amps to each spark plug? I wonder how he keeps his voltage regulator
cool. He'd have one of those aftermarket jobbies.

Assuming a really low spark plug voltage of 20KV that would be 880KW,
requiring 73,333 amps from his 12 Volt battery.

Yeah, right!

Also, 880KW is going to sap a fair bit of that horsepower. Especially when
you consider how much power the supercharger is using to turn it (seeing as
an "ordinary" hemi V8 can't even turn it.

 

Was watching discovery once... the 3 engines on the back of the space
shuttle... take one of those and when at full thrust will provide the same
power as something like 35000 V8 Chevys... and the supercharger (???) sucks
through 1 million (gallons or litres) of fuel per second.
But this was a while ago...if anyone can remember more clearly, correct
me.

Can't be right. Even using litres (smaller than gallons) 1million litres is
1000 cubic metres of fuel per second. Aint nowhere you're going to fit the
sort of fuel load required to get it up into space. (Especially when you
consider that it's got to carry the oxygen as well.)

Christ James, doncha go bringing facts and science into this.

What is the escape velocity required for a space shuttle, and how much fuel
does this require?

Escape velocity is a term we use when we want to escape from the Earth's
gravity. Well, we are not actually escaping from Earth's gravity. We re
actually going into what is called the gravity realm. So we don't actually
achieve escape velocity. That would actually be if were going at least 25,000
miles per hour. For our purpose, we go into a low Earth orbit we need about
17,500 miles per hour. So that is what we have to do is go from a standing
start up to an altitude of about 80 miles and get going to about 17,500 mph
and to do that it takes half of million gallons of liquid hydrogen and liquid
oxygen.

Remember, they do "fall off" once the shuttle has used them up.

The shuttle's main fuel tank, which holds liquid H2 and O2 has around
1,200 cubic metre capacity. It is 47m long and about 8m in diameter.

Here's a spark plug for you:

http://home.austarnet.com.au/mtaylor/500kV_Switch.mpg

The clip is about 1.5megs in size.

For those interested, if anyone, the "switch" that is opening is called
an ROI or remote operated isolator or air break switch.

An insulator connected to one phase of the ROIs flashed over and caused
it to arc during the operation.

All it's doing too, is to break the capacitive charge of the line that
it's disconnecting. There is no load on the circuit. If there were, the
ROI would've disintegrated. There's about 10 megavolt-amp reactive
(MVAR) involved.

The arc was extingquished by opening a circuit breaker further up the
line.

Is this a South African Space Shuttle or a European Space Shuttle?

 

I found it at

after a bit of poking around...

Its pretty cool

How about this "spark plug" though?

So that would be enough for 1.2 secs of burn then?

Err, my calculator suggest the volume is 2361 cubic metres.
