More NASA stuff

[boatme]

As some know my brother works at NASA he shared this with me today
I think it is way cool

Hope this attachment works

[RPM]

Those are some cool photos.. Whats your brother do at NASA?

[boatme]

This is his title

InDyne Imagery Support Manager
Kennedy Space Center, Florida

He is in charge of documenting many things that go on at NASA via photo and video

[JJ Apache]

Those were too cool!

[Sea-Dated]

Very Cool pics.....

[Roger 1]

Thanks for sharing those with us Marc! I'd love to see a launch someday.

that is so friggin neat! i don't care how old someone is, that is just cool!

[DollaBill]

awesome stuff. Looks like quad turbos on the main engines. I actually thought the engines would be larger.

I saw a night launch back in '96 and it was incredible from about 100 miles away on a clear night

[Perlmudder]

so the real question is, how much power are these engines making? 50,000 hp? 100,000 hp? 500,000 hp?

and can i get one in my new 50ft mystic...?

[cigdaze]

Awesome!!

About 37 million horsepower at liftoff.

Shuttle SRB test. :cool:

Those turbos are gas-turbine-powered fuel pumps. Each engine consumes approx. 25,000 gallons of liquid hydrogen per minute so they need a BIG pump.

It's true! You do know everything Chris!! :)

Anyone have some marshmallows and coat hangers? We can make s'mores.....:sifone:

You r making that up.

I'm a total dork. I love this sort of stuff and absorb it like a sponge. Especially the space program. I watched every Mercury and Apollo shot for every second they televised coverage. And read everything printed about it.

I was at a trade show a few years back in Orlando. My wife flew down on the last day and we headed East for the weekend. They had just redone the Saturn V and built the new building and she begrudgingly went along. I $hit you not, I looked at that thing for 3 hours straight. Every nut, bolt, rivet... If they'd have let me crawl up into it, I'd still be there. For me, it was the equivalent of the most devout Catholic visiting the Vatican and meeting the Pope.

[cigdaze]

Nope. I kid you not. 37 million horsepower.

The fuel pumps alone require 70,000 horsepower just to pump the fuel fast enough.

I love it. I about had the same religious experience. One of my engineering professors was the lead engineer on the Saturn V program, oh the stories he'd tell.

[Chris]

The Saturn V was an engineering and technological marvel. Some of the challenges they had to overcome were daunting. They had do ensure each individual engine ignited within milliseconds or the vehicle would have heeled over. The engines were so powerful that it requirted so much reinforcement in the fuel tanks that they would have been too heavy to launch. It took tremendous engineering skill to construct a tank that could overcome the inertia of the enourmous fluid mass of fuel that was being virtually instantly accelerated. otherwise, the fuel would have torn right out of the tanks.
The Saturn V was the fastest vehicle in the world from a dead stop to 100,000 feet. It was only surpassed decades later by a US fighter jet stripped bare for the purpose. They looked slow coming off the pad, but once they got going, they hauled a$$. This is my favorite- the Saturn V was the second-loudest man-made noise ever generated. The first was the atomic bomb. It was so much louder than expected, it knocked the ceiling tiles out of the TV broadcast booth 4 miles away.

well now you gadda tell us some!

[Perlmudder]

so what is the hp/weight ratio? comparable to a fighter jet? a top fuel dragster?

[Chris]

The Saturn V weighed about 6.5 million pounds and the first stage alone had 8 million pounds of thrust. Just shy of 1.25:1 TWR, while an F-22 fighter is about 1.05:1 and and F-15 is about 1.15:1. It's tough to draw a fair comparison to a top fuel dragster, which has intial acceleration far in excess of something that weighs as much as a navy destroyer, 32 thousand tons. But between 300 and 30,000 mph, the saturn walks away from the dragster ;)

Like a 47 apache against my 20 larson in 8-10s!

The sheer size and speed a space ship is simply mind boggling! Being an astronaut is still probably the coolest job in the world because so few have been to space.

With 37,000,000 HP even an Apache could go fast:sifone:

You know you're the biggest swinging dik when you need 70,000 HP just to run your fuel pumps!
