For Elon Musk =) Inverted Magnetic Gravity Well for a Controlled Landing

10/13/2017 1:33 AM

reason one less strain on any one point on the rocket and you could dump most of the fuel before landing to ensure no big bang however i'll miss that

reason two you could emp proof rocket and go the electromagnetic rout slowing it down faster if you wanted to more energy is required

reason three a wide entry point followed by funneling would account for any errors

Re: for elon musk=) inverted magnetic gravity well for a controlled landing

"...Inverted magnetic gravity well..."

'Inverted... well' suggests repulsion....in which case control would be difficult with static opposing fields. If it is not repulsive then are you talking about using magnets to pull the vehicle faster to the ground?

'Magnetic gravity' isn't a working concept with practical applications in the real world, AFAIK.

What types of distances are you imagining this to work at? Do you have any idea how much power you would need to have fields strong enough to support weight of such a vehicle at distances sufficient to make a difference? If you do, have you thought about how to deal with the heat generated in the vehicle?

They're not attracted to each other they are opposing polarities think the opposite formation of Magnetic setup to a bullet train large open cone with a opposing magnetic fields channeling the object with hundreds of pounds of force into a hole with a braking system made out of magnets of opposing polarities

you could do the same thing with air control simpler then indoor sky diving

Only if you are content flying a couple inches off the ground at best.

This isn't going to leave you enough distance to stop the vehicle without excessive acceleration.

Divert the mass to the centre of the cone then control the momentum from there dig a 300 foot tunnel for all I care then you'd have 300 feet the stop the thing does not matter at that point you know it's in the middle of the cone the cone is simply a means to control the area of which the device lands in it is not the braking system this thing it channels it into is the braking system you can spread the mass opposing mass out then use that opposing Momentum to channel to a focal point

If you aren't able to transfer momentum, then you aren't able to control it. If it is not providing any control, then there is no need for magnetic fields unless you are worried about the stability of the landing platform itself.

The problem is not that you can't dig a hole, the problem is the distance over which magnetic fields have strong effects.

As an example, generally for hard magnets (as long as you aren't really close) the strength of the field is well modeled as decreasing with the cube of the distamce....so the field is 27 times weaker just 3 times as far away and 125 times weaker just 5 times as far away.

.

If you aren't yet familiar with Earnshaw's theorm, you may find it helpful.

How will you transfer momentum, if you cannot transfer your thoughts to others?

So, did they blow up another lifter when landing, I have not heard anything.

Alex12: Why don't you come up with something like throwing a hat on a hook?

Inverted cones deployed, and tall needles, the rocket comes down between the four or three needles, and the cones catch, and help stabilize her.

a key Factor with space travel is weight another key Factor is Momentum is directly linked to the weight right by reducing the weight of the overall craft you can carry more load therefore a landing base that can Institute of control landing over a substantial area with a steady speed reduction would reduce the overall controls needed hypothetically could you just use a none flammable gas pressuriser in a massive storage container there's three ways you could do this off the top of my head alright using a non flammable gas pressurising it release it at the optimal time magnetic field with opposing polarities hypothetically sound although you would have to use a liquid and a combination of non flammable gas I would not recommend going that Rout giant ceramic speaker

Break up those sentences with periods, readers are having issues sorting out one of your thoughts from the next one. That is a suggestion.

The catch cones can be like parachutes, spring loaded KEVLAR, the apex being a metal catch ring. The rocket would deploy these like landing tripod, only they would be above center of thrust and center of gravity.

Think of it like creating an all purpose area to catch things of high momentum with a gradual slow down the problem is the load on an individual area is way too high this allows for control Momentum reduction over a general area insuring a almost perfect landing every time

Kevlar net might work but I don't think so reason why the weight of the net would pose too much resistance i think the net thickness required to stop a 3 tonne piledriver hurdling towards you at God knows whats speed

think of trying to catch a bullet with a net what we're not trying to do is catch the what bullet alright what where trying to is move the bullet a little to the left then a little bit to the right and then put it in the centre of the channel then progressively slow down the bullet

there is actually no way of just stopping the object

I was gonna make this thread make sense but........

I was gonna teach Elon Musk astrophysics until........

I was gonna land his rockets safely but I got.........

Wow. You don't seem to find any of the objections palatable. Okay, I'm going to try one of those feedback sandwich things... Something positive so you listen, then the debilitating criticism, then something positive in hopes that you don't just disregard the important middle info. Maybe it will ne easier to swallow the info and your pride in this form.

.

First, no one can deny you are enthusiastic!

Middle, that enthusiasm is misplaced. You are wasting your excitement about a solution you have dreamed up about something you don't understand. As an example, you have no idea of the speeds involved and your guess about the mass is off by an order of magnitude. You also need far more schooling in the fundamentals.

Last part. Your persistence and confidence could be great assets if directed appropriately. Be happy at the time you are saving by finding out now that you don't have a meaningful solution to contribute to SpaceEx, right now. That time can be used to great benefit harvesting the immediate low hanging fruit of education especially in areas such as physics and communication.

As Alex12 stated in his very first post here at CR4, "...I have limited knowledge of Engineering..."

To paraphrase a common expression, 'No kidding, Sherlock.'

Look up ballistics test all I'm trying to do is slow down the bullet then stop it without doing any damage to the bullet itself right contouring the momentum to a specific Point from their slow it down natural gas ship could just compressed some air the spacecraft would perform a fuel dump then you would simply creative structure a couple hundred feet tall some buoyancy run a s*** ton of compressed hose create a multi-layered release compression system over that and then use x amount of kilos or pounds of resistance steadily applied Force the opposing Direction hypothetically if you have enough natural gas ship you can probably even stop hurricane hot and cold air

You can probably do the same thing with like a really finally controlled controlled magnetic elevator and ground sensors sense where the object is coming from elevator itself would be able move side to side to within a certain area alright the elevator would create sort of a catching a action the momentum and then follow the momentum of the object steadily applying Force

The last time you escaped the home, you wrote this:

"Metal Storm with Rotating 10-30 X 3-10 36-360 round each barrels/magazines with individual suspension increase the spread of the metal storm covering multiple trajectories at once creating small scale trajectory nets isolating areas that you don't want things to pass through large scale version of it could be used to fire rounds consecutively almost all vehicles and with the rights sensory technology setup it would take naval vessels down extremely easily they are very slow moving and are very big Target When compared with jets and other items used by the military"

No, be a good lad and go back to the home and take your meds.

He needs to study grammar, and 7th grade maths before he goes off to test-engineering school (as the dummy for the acceleration test).

These run-on sentences clearly indicate a need for brain chemistry modification, so your answer was spot on. It is nothing a case of beer might not solve.

Re: For Elon Musk =) Inverted Magnetic Gravity Well for a Controlled Landing

Hello again.

Your still a bit all over the place with your ideas, could you perhaps post a picture and some bullet points of a proposal and leave out the theories of proof of concept (we can handle those).

For a workable solution, currently I am leaning towards a net over a canyon with the net held in place by a pulley system that gradually increases in resistance to slow down the object in a controlled manner (protecting the object and the capture device from damage) and can then lower the object to the ground for retrieval. The point being safe capture first, some small fuel reduction second. Concept only, it still won't be feasible in the real world.

Problems are, well getting the object to that particular location which is not as easy as you might think by the way, hence the massive cost and effort to get a landing platform on an unstable water surface perfected.
