2. More than a hundred years ago Konstantin
Tsiolkovsky called mankind to the creation of
long-term human settlements in the open space.
Such settlements he called «essential cities.» But
only now his dream began to get real outlines. At
the present time about ten countries of the world
have already announced their plans to establish
in the space of human settlements. The next
placement of the first such settlement in space is
planned for 2015. We do not yet know what will
be the design of the first space settlements.
However, even Tsiolkovsky recommended in the
creation of essential cities use the cable-stayed
structures. It is this constructive direction in the
construction of essential cities is devoted to the
presentation.

3. Since about 1983 I have been designing and
researching various cable-stayed structures. It
turns out that from the system of flexible
cables, you can create quite large and quite hard
structures. To those who are interested in it, I can
recommend to visit the page of the British
encyclopedia entitled «Space Architecture»:

The using of cable-stayed structures in the outer
space buildings has a lot of advantages, among
which I would like to note their maintainability: in
the event of damage to any of the cables, it may
be replaced with a new one without damage to
the structure as a whole.

4. If we have a hard support contour for a good
cable-stayed network creation, we will get the
space platform, which can be used for
different purposes. On the basis of such a
space platform further we can create, for
example, multi-store construction by blocking
several such platforms in the vertical direction.
Apparently, the first high-rise construction,
which will be aimed on a long-term residence
people in it, will become a multi-storey space
hotel. In this hotel, the people will live a few
days, and then the space Shuttle will return
people to the Earth and moved to the hotel of
new tourists. My project of such multi-storey
space hotel is presented on the next slide.

6. Many, probably, can not have absolutely clear
understanding the design of this hotel and the
appointment of all its elements. Let's consider this
structure from the beginning. Each space platform
begins with the support contour. And each support
contour begins with an one contour element. I
suggest to create a support contour from series of
elastic plates, which are long and hard at the same
time, for example, of stainless steel. As a contour
elements can also be used rods tubular cross-
section. One the outline element in the form of a
long plate is depicted on the next slide.

7. In the middle of the plate is made the hole for the
original plates joining into the pairs. At the ends of
the plate - openings for the connection of contour
blanks between themselves. In addition, there are
few holes (at this picture of their eight) to further
attaching of load-carrying cables to the contour
elements of support contour.

8. After joining of linear elements into pairs, we get the
following cross-type workpiece.

9. By combining a series of cross-type workpieces, we
get a support contour. Below shows the support
contour of 32 full-color cross-type elements. After the
installation of all elements of the contour all contour
nodes have to be forced for the stiffness. Green
closed line we will consider as the first contour, the
red line - as the second one.

10. After the creation of the cabling network for the first
contour and the subsequent creation of the second
network for the second contour, we get a very tough
double-layer joint cable-stayed network. I consider
such network as the «field for further construction».
About the schemes of joining cables into the network
will be told next.

11. For creation the living rooms of the space hotel can
be used inflatable construction of the «Bigelow
Aerospace» system (see
http://www.americaspace.com/?p=30033 ) or similar
to them in the form of a capsule from a hard
material. These capsules can be, for example, four
in one level.

12. These capsules can be and another quantity. One of
the variants of formation of the «residential floors» of
the six residential boxes and possible their mutual
location are shown below.

13. During the construction of the outer hotel
accommodations living boxes are placed directly on
the cabling network of the formed as described
above space platform. Boxes are attached to the
nodes of the network of special anchors.

14. Similarly we can build the second floor of the hotel
with the same number of residential boxes. The
second floor support contour is mounted at the upper
nodes of the first floor contour.

15. Then similarly we will build the third floor.

16. Then we will build the fourth floor and so on...
Because in space the stores practically will not put
pressure on each other, they can be combined in
very large quantities

17. When the very upper floor will be mounted, the living
boxes should not be placed to it. This floor I call
"technical floor", it will serve as a «launch site» for
the arrival and departure of the space Shuttle.

18. And here came the «space Shuttle». We assume
that into our cosmic hotel profits of the first tourists!

19. I want to add the following: in this project I for great
visibility showed very dense cable network in my
space platforms. The real cable network in space
can be much less dense. For communication
systems between the living boxes all communication
cables could be laid along the cables of my network.
After the release of the space Shuttle all «guests»
will be able to go down to the floor, they need, right
between the cables of network. In the absence of
gravity for them to do so do not even need an
elevator. Since each inhabitant of the hotel will have
the space suit in his room, sometimes they will be
able to make their walks on the cabling network
directly in the open space. In the presence of such
my network on each floor they, I think, will not be
able to get lost in the open space.

20. I recommend space tourists placing just in separate
boxes. Proposed earlier before me scheme of boxes
blocking of «bunch of grapes» type (see in Russian
http://www.membrana.ru/particle/547 are much more
vulnerable in terms of survival of the inhabitants of
the hotel as in case of various technogenic
catastrophe and the meteor attack.
Created from the top of the hotel landing site for the
space Shuttle will provide him a soft landing due to
the fact that cable-stayed network will soften the
blow.

21. For all of my cable-stayed networks there is only one law
of their formation. I opened this law back in 1989. Its
name is «The Law Compatibility of Quasi-ortogonal
Tangentially-undulated Cable-stayed Networks». This law
allows to obtain the scheme of creation for any network of
my class for the case of any beforehand specified
number of waves on the support contour.
In the basis of all the endless series of my cable-stayed
networks is laid my «Inventor's Certificate SU № 1270256
A1». More in detail about the law, which was opened by
me, you can read in my article «Discovery in Mechanics»,
which was published by the «Agency of Technical and
Scientific Information, Scientific and Technical Library».
