Pyramid rocket launcher for the Enviornment
« on: 09/25/2005 08:25 pm »
tried to edit the word pyramid but I waited past thirty minutes to catch the error. sorry

Let me elaborate on my Idea
The four sided pyramid's steel roller bearing hydraulic plates would close quickly behind the rocket as to rises, increasing lift and channeling the exhaust to huge massive compression tanks to be recycled with various compounds as fuels to be burned again to power steam generator turbines.

Also... The precision ability to raise the ground level for the first 3000 feet or so behind the rocked would obtain more thrust momentum at launch.

I realize, I'm talking mega bucks to build something like this.
It would be such a good thing for the environment to harness some of this tremendous rocket power at liftoff.

I apologize if this is the wrong forum for this.

How much extra lift would it gain?

One problem. Rockets don't go straight up. They pitch and roll right after lift off. Roll manuever on the STS is completed one mile up (Slightly less actually).

I don't get it. You want to build turbines that might get about 10 seconds or so of drive, one km high, costing maybe more than a billion dollars, and I'm not sure if you'd get extra thrust, while risking the sound supression system being beefed up as you're creating more damaging acoustics with this?

Oh I see, your plates at each level close as the assent is progressing? You know they would have to be made of something very special to withstand the force and temps. Plus they'd have to close against huge downforce, but I see how that would re-direct thrust exhaust.

Yes.... You are so right of course.
 I did know that fact before my crude drawing. But I realized that an off sided pyramid would be way less stable and harder to build.  

My hope, at the time of the drawing was that maybe the pitch and roll maneuver could be changed to start past the kilometer high point.  

Hey listen please. I mean no disrespect here at all.

I just need to get these ideas out of my head while there is time.

I also have this idea, for a super charged black laser spectrum light to be used in space to examine the properties of the Higgs Field.

Think the roll for STS is that the pads 39a and b were made for moon missions but don't face the correct direction for trips to LEO like the station, so instead of moving the pads, the shuttle just rolls. The pitch is obvious.. no pitch one balistic ride.. :(

Its an interesting concept, but I see a tiny snag...

Wouldn't the cost to the environment of developing such a cavernous structure probably be even more damaging to the environment?

Of course, if we could develop a booster which only uses LOX and LH2, then the only by-product of a launch is water vapour, a bit of residual heat and the obvious noise effects.   So I'd rather see that development money put into replace the Shuttle/SDLV's Solid boosters with liquid versions able to do the same job.   Could we revive the old USAF fly-back booster's of the 80's maybe?

How?  Thrust is provided by propellant mass exiting the rear of the rocket, not by anything it "pushes" against.  How would rockets work in vacuum otherwise?

That's what I was thinking. It's the old concept of what is pushed out is what pushes you forward, not what you're pushing against.

As far as capturing the exhaust thrust from launch, maybe you could take a typical pad fire pit and convert it? You may be on to something there as the exhaust from the SRBs is poisionous. I don't think they can even go to the pad without breathing equipment until several days after a launch.

Here would be one place:
 Of course, that would be only helpful. Exhaust will still go everywhere.

I began thinking about this all after reading an article by Mr. Paul Hill.  The good one.

I can't find that exact article now.

It's possibly an Idea that has little merit.

I just thought it would be nice to harness some of that power at liftoff and use it for another constructive purpose.

At lift-off, the entire system weighs 4,400,000 pounds (2,000,000 kilograms) and stands 184 feet (56 metres) high. During launch the boosters and the orbiter's main engines fire together, producing 7,000,000 pounds (31,000,000 newtons) of thrust.

 It's such a nice Monday.

I thank You all.

lol

If you can kick that football across the Atlantic barefoot, then maybe I'll play.  It's still a nice Monday to laugh.

Stay calm my friend. I didn't mean football wasn't cool. It certainly is.

 I just prefer reading astronomy.

Pffft, they're wimps! We play a very similar thing down here, no padding, and you actually have to touch the ball down to score!
