THE PRESENTATION OF YABLAM
Yablam is a new method which was developed for carrying utility cargo to the orbit in a safe way with a little cost. It is more advantageous compared to classical rocket ships from the point of view of cost and security. Yablam stands for “Yavuz Baştürk Launch Method”.
Yablam, is composed of lengthening a hose to 185 km above the surface, carrying weight of the hose by sharing by intermediate stations and rising the utility cargo via the hose in lift cabins. System, briefly, aims to launch rocket ships, which carries cargo, in a horizontal way, not in a vertical way, to the space from a launcher which was made 185 kilometers above. Therefore there will not be the air friction problem, it can be reached to orbit speed with a very little fuel.
Elements of the system
· Fuel Hose
Rocket ships do not storage the whole of the fuel ,which will be consumed, in their own structure. Fuel continuously pumped to all of the rocket ships in the system from the tanks on the surface by pumps which run by electrical energy. The fuel hose will probably be produced from Carbon-Epoxy material which has got optimum values and is available easily and the cheapest material in the market. There are alternatives such as Kevlar/dyneema rope. Another function of the fuel hose is that it is also the lift rope. Lift cabins will rise up on the hose by electrical energy.
· Type of the fuel
It will be used hydrogen/oxygen as fuel. H-O can be stored tanks on the surface in huge quantities and pumped in liquid or gas form by the hose. For making the system more secure and making the hose lighter and more simple , there is also the alternative of pumping water only. Water appropriate to electrolyses (for example salty sea water) is stored in big pools on the earth. Electrolyses equipment in the stations simultaneously decomposes water into hydrogen and oxygen by using the high voltage line which exists along the hose and supplies to the rocket ships.
· Electrolyses equipment in the stations
If liquid water is preferred as fuel, Electrolyses equipment in the stations simultaneously decomposes water into hydrogen and oxygen and supplies to the rocket ships. Decomposing water in the stations by methods, which are out of electrolyses, is also a research matter.
· High voltage line
There is also a high voltage line on the 185 km hose in a vertical way. Fuel pumps, which exist on the earth and in the every intermediate station, will run by this electrical energy. Lift cabins, which will rise up, will also rise up by this electrical energy. If the type of fuel is preferred as water, electrolyses equipment which exists in intermediate stations will decomposes water into hydrogen and oxygen by real-time electrolyses by this electrical energy and transfers to rocket ship as fuel. Other electronic equipment on the hose and in the stations will also provide their power from this line. Electrical energy can be produced by any kind of method on the earth. Fuel oil generators, mini nuclear power stations or city electrical network can be used.
· Intermediate stations
It is difficult for the 185 km hose to carry its own weight and intermediate pumps by the materials which are in use today. Therefore weight of the hose will be carried by fixed stations which are on every 10 km. station can be imagined as a metallic disk at a diameter of 20-30 meters. The fuel hose passes through center of the disk and station is fixed on the hose. There are rocket ship, pump and electrolyses equipment in every station. Rocket ship in every station will be designed as that it can carry station equipment and the 10 km rope below and lift cabin in addition. It will be understood by the estimations which every kilometer the stations will be fixed on the hose. 10 km is an example value.
· Pump on the stations
It is impossible to raise the fuel 185 km up by just one pump. Therefore there is a pump on every intermediate station which runs by electricity. Every pump will pump the fuel which comes from the pump below to the pump above at an appropriate pressure.
· Navigation& Communication equipment on the stations
It is required to hold all of the stations and the hose on a virtual 90 degrees vertical line as a 185 km vertical structure. Therefore there will be GPS or a similar installation system on stations and the hose. Because the rocket ships have got exhaust outputs on XYZ, station will be moved by rocket power in required direction automatically. A special installation system for this system can be produced from zero by GPS transmitters located on the earth.
· Lift cabins
Lift cabin will carry satellite, human or any kind of material required to be reached to the orbit. Because every station in the system has the ability of carrying lift cabin, if there are 18 stations in the system, 18 lift cabins will simultaneously rise up on the hose by electricity. When the lift cabin reaches the top station at a height of 185 km, launch preparations at the horizontal direction are started. There are a rocket engine and an empty fuel tank in every lift cabin. The tank in the cabin is filled with fuel at the height of 185 km. Then the cabin is released into space and launched in horizontal direction. At this height, the cabin will reach orbital speed and utility cargo will enter the orbit. After it enters the orbit at the height of 185 km, if required, it can be reached the orbital height required with a little fuel. Lift cabin and the rocket in the cabin is disposable. When the satellite is reached to required height, cabin and rocket are fired by letting it fall into atmosphere.
First launch of the system
Before the Yablam is launched, 185 km fuel hose stands on the earth as coiled around a bobbin. The hose is full with fuel. The stations are fixed on the hose every 10 km. Electricity is produced in the line on the hose. Fuel pumping starts and the first station began to rise up by the rocket power. Because there is not escape speed& fuel storage problem for the rockets on the stations, they can rise up with a speed such 30 km/hr. the first station rises up 10 km by dragging the hose below and the rocket power is lessened and the rocket is suspended in the air in a fix point like a helicopter. Meanwhile, second station is prepared to launch on the earth and the second one simultaneously starts to rise up in a synchronic way. When all the stations rise in the same way, we will have a 185 km vertical structure. After all of the lift cabins are launched into the orbit, the yablam hose will go down into the earth in the same way which it is launched and the system is closed by packaging on the earth. Yablam will be 6-7 hours or a few days in air just when it will be used, it will come back to the earth when it completes its mission.
About the system’s weight
Fuel in the hose does not create a weight for the system. Because the fuel is continuously pumped by electricity which is produced on the earth and is continuously in movement, it does not create weight. But the fuel flow must not stop even just a second and the required quantity of fuel must continuously pumped. If fuel flow stops for a second, the fuel in the 185 hose will turn into weight and the system will collapse by its own weight. If the fuel is pumped more than required, excessive fuel will be released out. Every rocket in the system carries just itself, other equipment on the station and the empty hose piece which extends to the station below. Every hose piece carries just the hose piece which extends the station below too. If required distance between stations is estimated as 4 km instead of 10 km for this, the distance between stations will be designated as 4 km.
About economical value of the system
Lift cabins in the same number of stations will simultaneously rise up. A new utility cargo will be entered the orbit in every approximately 20-30 minutes depending on the cabin’s rising speed. Therefore space hotel, lunar hotel, commercial manufacturing facilities in areas without gravity, meteorite minor ships, inter planet passenger ships, transfer of pieces of inter stars passenger ships, assembling them in the space will be a reasonable aim for human being. 2-3 satellites at most can be launched by classic rockets and there is a explosion risk 1/33. Today, the cost of carrying one kg material to orbit is at a range of $10,000. Investment cost and freight cost per kg of carrying to orbit will be very less by the Yablam Method.
Comparing to space elevator project
Space elevator is designed as a rope from the earth to 100,000 km up. This rope is stretched by centrifugal force and gravity and can stand as a vertical structure. So lift cabins can rise up on this vertical structure. But it is impossible to produce space lift under present conditions. Because the only material which can lean against such a stress is Carbon nano tube. Production of sufficient quantity of carbon nano tube is not an arguable matter and it can not be guessed when it will be possible. Even if it can be produced in sufficient quantities, the cost of the space lift is guessed between 7-15 billion dollars. But the Yablam idea can be produced with the materials available by relatively very less investment cost. Because the space elevator is in vertical position, it must lean against conditions such as space garbage, meteor dust, negatively weather conditions. Either these are not such kind of risks in Yablam Project or very little.
Security evaluation of the system
Because standard rockets carry in huge quantity of fuel, it is nearly impossible the personnel to survive after an explosion. Because fuel is safely stored on the earth in yablam project, a big explosion risk is too little. There is not huge quantity of fuel in the rockets in fire. If assumed that a rocket explores, valves, which are fixed on the hose in periodical distant, will be closed automatically and the severity and effect of the explosion will be less.
During the explosion, security rockets in the lift cabins which are rising up, will be launched and the cabins will go away from the hose in a vertical position. Then they will reach the earth in a safe way by free falling and parachutes. The system can be launched from a vessel on the ocean or a desert against the risk of the 185 km hose filled with fuel on inhabited place. When a design is developed which will pump water to hose instead of H-O, the risk will be reasonable.
Because the Yablam will stand for a certain time, the most appropriate weather conditions will be waited for. Despite possible jet streams are very strong winds, it is possible to overcome them by low air density at that height, small cross section of the hose and the low rising speed of the system. In south and north poles, jet streams are always zero. If jet streams will be a serious problem, the system can be built at polar points.
Because there is not high quantity of fuels in the rockets, it seems that there is no big explosion risk. Therefore risks for human being are less. All the fuel is stored in secure places on the earth.
If it is decided to pump water instead of H-O, breaking of the hose will be a high risk people living around. In that case, Yablam can be launched from a vessel on the ocean or desert.
Bobbin-like structure, which the hose is coiled, on the earth must round at the same speed with rockets’ rising speed. If we assume that rockets will rise up at the speed of 30km/hr, 8,3 meters/s rounding speed seems reasonable. As an alternative solution, 185 km hose and 10 cm diameter are assumed, it will cover185km*10cm = 185,000,000 cm2 of area, therefore an area of 300m*300m is considered enough. When all the hose is spread over the area there won't be any friction problem.
Yablam is now just at idea stage and just the patent was taken out. Any required estimations and researches aren’t carried out. Just 30-50 people have positively thoughts on this matter. If my opinion is considered appropriate, I would like it would be a scientific article or master thesis
