A way to fly without fuel (my project)

How to fly away without fuel ... a hint of a perpetual motion machine ... well ... not really ...
We are all at the bottom ... atmosphere of course ... what did you think ...
So ... the pressure per 1 cm3 is somewhere around 1 kg ... although it already depends on the weather in clear weather - it presses more, but less in cloudy weather ... some people feel it ...
Archimedes will not let you lie; there is his Archimedean force both in water and in the air, in order to emerge from the water, the divers simply take a strong bag and take air from the cylinder (if the diver did not exhale all the air in the water) ...
In the atmosphere, warm air (balloons) is sometimes used for lifting, since warm air is lighter than cold air, it rises up ... gases are also used: helium and hydrogen ...
Helium is expensive, but not combustible, and hydrogen is not very expensive, but it is very combustible ... the fact that only hydrogen is formed during the combustion of hydrogen does not convince you to use it here ...
According to my project, instead of warm air or light gases, vacuum can be used ...
Of course, you say, the vacuum will flatten the ball and nothing will fly ...
  

That's right ... because the ball should have a margin of safety and should be made of light material ... now they are different ... the "volume" is not bad to make from duralumin ...
I won’t write much about the intricacies of truss structures ... I’ll say that the “volume” can be with arches ... internal struts ... the main thing is completely tight ...
After pumping out the ball’s inner surface, the air will not corrode ... like the outer one when flying high ...
Such a ball does not need to be constantly filled with combustible or expensive light gas ... just if necessary, pump out the air ... and control the tightness ...
Compared to the “thermal ball”, the “vacuum ball” needs a smaller volume (theoretically), but due to the weight of the ball itself, it grows (practically) ...
In general, efficiency depends on the lightness of the material ... you can not necessarily make a ball, but any other shape ...
It is also not bad to make small vacuum balls that can be combined into large beams ... depending on the weight of which you need to lift into the air ...
The ball can reach a height of 40-45 km (the altitude and speed of rise is, in principle, regulated by a vacuum pump) and will hang there for a very long time (than not the “geostationary-stratospheric satellite”) ...
These balls (not to be confused with sales)) can be used to launch rockets with satellites into the stratosphere ... from where it is easier to launch (less fuel for rockets) into space ...
It is possible to make a cable elevator to a height of 40-45 km (there is no wind in the stratosphere - the ball will not blow off) ... at the top there is an observation deck for tourists ...

A project using a substance with a negative density has not yet been considered? or I'm already late.

Under normal conditions (and in physics this is 20C, 760 mm Hg, at sea level, with g = 9.81), per 1 sq. Km. m the atmosphere presses about 10 000 kgf. On 100sq.m - about 1 million kg, respectively. So 100 square meters is not a very big ball, only about 93 cubic meters. There is such material to mold a ball weighing less than 120 kg with a volume of 93 cubic meters. m? Definitely - no! And not soon in sight. Chip number 2: with increasing height, the atmospheric pressure and its density decreases, and the lifting (pushing) force of the hard ball also decreases. This is a minimum that you can take into account and not even try to make plans to implement this initially stillborn idea. I'm not talking about viewing platforms for tourists at an altitude of 45 km, from which they either fucked drunk or, wanting to give a damn about everything from a height, take off their helmet and burst at almost zero atmospheric pressure. "and only small smelly lumps ...."
And such a grief of inventors, a modernly-uneducated shkolota must be driven out of the net by a filthy broom, but not just to the point, but with real school books and harsh Soviet-style teachers. And then divorced, fucking, wise !!!

It is theoretically possible, even if these balls are collected in clusters, the problem is in the structure and material. The mass of the ball will change to the mass of pumped gas, with the mass of the device (ball, basket or other device / payload) of 10 kg. And a volume of 10 liters, respectively, will fit 10 liters of air, the density of which ... And, to hell, it is unprofitable in general

yes, Wilm worked in France ... as an engineer contributed to bathyscaphes in general ...
And Auguste Picard created Trieste; his son Jacques Picard helped him ...

You have a lot of strange literature published there, so no wonder. But it spins cool. )))
In fact:
1. William Bill - American biologist, in the 1930s immersed in the bathysphere, and not at the bathyscaphe.
2. Pierre Wilm - French engineer, really engaged in the design of bathyscaphe, but had nothing to do with Trieste.
3. January 23, 1960 - as you write correctly, the date of immersion of the Trieste bathyscaphe to the bottom of the Mariana Trench. But this not creation date!

he met in different ways, they write both William and Wilm Biib - an engineer (worked in France) and Auguste Picard - a scientist, they are the creators of the bathyscaphe ... January 23, 1960 is the date the Trieste bathyscaphe sank to the bottom of the Mariana Trench, depth 11022 m. ..

Valery, I found out about tanks ... I want to buy)) .. The large tank car itself has 162 m3 (162m3 * 1.29 kg * m3 = 209 kg - lifting force when fully pumping air out of it, max (passport) pressure 8 MPa (8000000/101325 = 79 atm) ...
Water will not flow out of the tank ... the vacuum will not start ...

Dmitrij an interesting idea .. like Kite (in kitesurfing) is inflated ...the pressure in the middle of the fabric gives it a shape and does not allow it to bend ... and with more pressure, the shape is harder and harder to bend ... Kevlar fits here ... I wonder what pressure will probably be very small ... you will not envy Kevlar ...

Valery,
I agree about the partitions, their task is to prevent the liquid from splashing ... otherwise it will turn around ... Spacers-truss structure (corners, channel) here (in vacuum) should only be for keeping the internal form ... Like an inflatable balloon in which some plank (imaginary) frame does not allow it to lose shape (the walls can be thin, but it must hold the shape rigidly) ...
You were having fun with the balancer ... you saw on the canal when, after firing a shotgun at the bottom of a full cylinder (with nitrogen), it did not explode, but took off with a rocket, then hung in the air when the gas gradually ran out ...

It didn’t work out long ago. And the liquid is pumped out by pumps. A sleeve is connected to the nipple. The valve opens and forward.

UR-R-RA !!!
EUREKA!!!
... Well, you can just make the tank thick-walled !!! (That’s, five centimeters of alloy steel). Then pour water to it to the top !!!. Close the top hatch, open the bottom ...
... Water will pour out, a vacuum will form there and the tank will take off !!!!
Gee ... It's simple !.)))))

When the hatch is closed and the liquid is drained through the lower nipple, at some point the walls of the tank are deformed ..

Please, next time, observe, please ... Before the walls fold in, are there a bit of wheels coming off the rails?

If you do not believe your eyes, how even a slight decrease in pressure crushes thick-walled containers, you can continue to remain in your delusions. ((

Well, but there were no special struts in the middle.

There were !!!!!. There are no transport tanks without bulkheads !!! Their function is slightly different - not to increase the stiffness, but to minimize the movement of the liquid, but they are always there !!!
P.S. I recalled from my youth ... They somehow sentenced a hog ... They decided him by a conspiracy committed by a group of persons ...)))). They started to grout - the gas in the cylinder is over ... I went to my grandfather for the cylinder. (Not far, 100 meters ...). The cylinder turned out to be two-thirds empty, judging by the frost on it ... (The liquid fraction occupied only one third).
I, by virtue of youthful maximalism, jealously suggested that I bring it myself, "Just put it on your shoulder!" ... (There were women).
They threw me ... Together ... Sharp !!! And then they wondered why I ran so abruptly right away ...))))
..... So I ran these hundred meters and sprinted at a speed, barely having time to sort through my legs in order to catch the balloon flying forward, which, like a rocket, pulled me forward, lying on my right shoulder .....
Just flew into the yard, I realized that we must somehow stop ...)))). Here, or "peck down" and fall forward ... Or fall sideways ... I chose the second - good, winter, snowdrifts ....

Imagine a pumped-up bicycle camera. Only in our case it will not be a circle, but a ball. To compress the ball, you need to compress the pressure even more inside the chamber, and it, accordingly, must be such that it cannot be compressed.

IMHO, arrived yesterday almost in a dream)))

where will the air be under pressure

Ltd!!!!!
That is, with each inflated atmosphere, we multiply the mass of air ....
And why, then
the air in it will weigh a little

It is necessary to make a ball out of fabric with a vacuum chamber inside. That is, a double-walled ball where air will be under pressure. Nanotissue is much more real than duralumin. To make the camera sooo small in volume, the air in it will weigh little

Sometime may invent lightweight durable material

It is better to invent a very light vacuum. But even he will not save your crazy idea.

on YouTube, I saw a wagon tank (on 8 axes) ... flattened ... because it was washed inside with boiling water from a stream ... then it was closed ... then it started to rain and it flattened, because the air was in the middle at first it expanded from heat, and then, after a cold rain, it contracted ... without any pumps ... Well, but there were no special struts in the middle ... they must then contain the pressure .... Sometime they may invent a lightweight durable material ... then everything will turn out ...

I myself observed a “folded” three-ton barrel. And it flattened it with very little pressure - the tractor pumped the sewage pit “air” ... (This is when the air filter is removed, instead of it a suction sleeve is put on the pipe, which enters the top of the tank. The tractor engine runs at high speeds, sucks air from the tank, and a vacuum is created there. And along the second sleeve, cut into the tank already from the side, liquid from the sewage pit is sucked into it).
So, the sleeve that was sucked from the pit was lowered too low (slipped) and hit the bottom. The tractor driver did not notice this ... After some time, the steel barrel with a bang folded inside !!! Despite the bulkheads - they cringed and bent ....
And the barrel was made of fairly thick steel, and the tractor was the most common MTZ-80 with the D-240 engine .... And the barrel folded like a paper ....
By the way, this three-cubed steel barrel weighs even without a chassis, I think, a couple of hundred kg !!!))))

... with duraland, .
At first, of duralI. Secondly, your vacuum ball will shrink simply when the pressure in it decreases. Give the calculations of your "miracle".

(this is not the first jump from 39 km at all)

Compete on the accuracy of the jump ... If you jumped and hit America - bronze. Silver to North America .... Gold to the USA !!!

you probably had in mind to pump air in the fall ... there on that photo the Stratonaut also parachutes into it from behind ... flew successfully ... reaching supersonic speed (this is not the first jump from 39 km at all) ... I from thought ... if someone wants to shoot a "ball" then he, too, will not quickly fall but will gradually fall ... like a parachute ...

duralumin is 3 times lighter than steel with the same strength ... not to mention modern materials and alloys ... which are used to replace steel ... Aircraft are not made of steel, but with duralumin, titanium or carbon fiber ... on top there is a “cube" without vacuum the advantages are less pressure "at the bottom" ... here the vacuum is regulated by the pump depending on the required load (elevator .. cable, etc.) ... which cannot be said about using helium ....
On January 23, 1960, William and Picard created a bathyscaphe, which sank into the ocean to a depth of 11022 m (1102 atm); there 4 mm steel will also not stand ...

you can also fly without a rope ... like on a balloon ... you just don’t need to burn gas to heat the air ... like on a balloon ... how many rich people are paying big money now to fly back and forth into space ... on photo altitude 39 km above the Earth ... the stratosphere ... isn't it beauty ...

So on Everest, too, there is nothing to breathe and cold ... but they climb a lot ... We must ... we will make all the conditions ... but there it is warm (in the stratosphere) where +20 Celsius ...

You can still make a vacuum parachute.You fly from space to Earth, the ball is slowly increasing in size and there are no overloads, burning in the atmosphere, and so on. Slowly calmly sit yourself

here, as an option of delivering the "ball" to the height with an open valve (without vacuum), and at the height of the valve close and pump out the rest of the air (there will not be much air in the ball anymore during the rise) ... and the pressure is less the walls will be (in a hang) ... but there should still be a margin of safety ... to hold loads ... a rope ... an elevator ... tourists ...

you, as I understand the engineer ... yes, there’s a little “snag” with the material of the rope, it should be 40-45 km ... well, maybe from Kevlar ... carbon fiber ... from the web (the web is one of the most durable and light material in wildlife) just before creating spider farms ... so that the spiders try to weave a web (of course there should be a thick braid of small strings) .... another option is fiberglass .... titanium rope ...

now everything is in order ... yes, the pressure will go crazy on the surface of the sphere ... but the lifting force is big ... here, as an option, you can deliver a "cube" without vacuum to a height (with an open plug up to 40-45 km) ..and already there to pump air out of it ... so it will press less on the walls (during the ascent from the "bottom") ... but buoyancy will remain at a height ...

Flight? Where to? Up the rope? This is not a flight, Imho. This is a "ride" up and down. "Observation deck" at 10km? There is nothing to breathe and almost nothing is visible. The lookout in a balloon is somewhere up to 500m.

Oh, you love the projections, not confirmed by calculations!
Low pressure will shrink your ball long before the vacuum. )))
A simple example. RVS-100 (a vertical steel tank with a volume of 100 cubic meters) has a shape close to the cylinder, the wall and bottom thickness of at least 4 mm of steel, a mass of about 10 tons. And the safety valve works if the pressure inside decreases by 20 mm of water relative to atmospheric pressure pillar! Only 20 mm of water!

It remains only to add the weight of the cable to the calculation. After all, He must be very strong. And it will become clearer. Such a project exists in theory. There are no suitable materials for cable. Yes, nanotechnology will help :)

A cube of air weighs 1.29 kg, it takes about 100 cubic meters to take off, that is, a lifting force of 129 kg.

Well, what pressure will be on the area of ​​the ball? It will be measured in tons, probably not a single material can stand it. And even if it does, the weight will become too much. But the idea is cool.
