Abstract

The updraft power plant is constructed from a flexible tube forming the tower, and as this tube is of light construction, its weight can be supported at the top by a captive balloon or by buoyancy gas chambers built into the tower walls. The captive balloon is so arranged that the upper end of the tower forms a wind scoop and turns constantly into the lee of the wind. The low pressure field behind the upper tube end therefore induces an updraft in the tower, and this energy is used by a turbine located at the foot of the tower. The airstream enters the tower first via a shallow roof structure close to the ground containing guide vanes, which rotate the entering air and prevent it from streaming across the entrance to the turbine and being wasted. The higher the tower, the more efficient the plant, and as the cost of the tower itself in relation to the cost of the entrance structure, is low, it thus pays to build the tower as high as possible.

Aufwindkraftwerk mit Schlauchturm, Fesselballon und Leitschaufeln am schwebenden Vordach Aufwindkraftwerke sind schon seit etlichen Jahren bekannt. In der Übersicht über mehrere Aufwindanlagen im Solar Energy Digest, Vol. 6, No. 5, May 1976, wird das generelle Prinzip des Aufwindkraftwerkes beschrieben. Unter einem Glas- oder Folien-Vordach (siehe Skizze 1.1 oder 1.2 ) wird Luft erwärmt und strömt einem Turm zu, an dessen unterem Ende eine Turbine installiert ist. Die warme Luft strömt im Turm nach oben. Je höher der Turm ist, desto besser wird der Wirkungsgrad der Anlage, da die Energie der aufgewärmten Luft bei einem niedrigen Turm nur teilweise ausgenutzt werden kann. Die Kosten des Turmes sind im Verhältnis zum Vordach gering, so daß , sicF) in jedem Falle lohnt, den Turm so hoch wie möglich zu bauen. Dies ist bei Türmen, deren Gewicht nach unten auf den Erdboden abgetragen wird, nur bedingt möglich.Updraft power plant with hose tower, tethered balloon and guide vanes On the floating canopy, updraft power plants have been known for a number of years. In the overview of several updraft systems in Solar Energy Digest, Vol. 6, No. 5, May 1976, the general principle of the updraft power plant is described. Under a glass or foil canopy (see sketch 1.1 or 1.2) air is heated and flows towards a tower, at the lower end of which a turbine is installed. The heat Air flows up in the tower. The higher the tower, the better the efficiency of the system, since the energy of the heated air is only partially available in the case of a low tower can be exploited. The cost of the tower is low compared to the canopy, so that it is definitely worth building the tower as high as possible. this is only conditional in towers whose weight is carried down to the ground possible.

Denn je höher der Turm wird, desto stärkere Druckspannungen müssen die Wandungen am unteren Ende des Turmes aufnehmen.Because the higher the tower, the stronger the compressive stresses take up the walls at the lower end of the tower.

Deshalb wird hier ein Turm vorgeschlagen, dadurch gekennzeichnet , daß sein Gewicht von einem Fesselballon oder durch Auftriebs-Gaskammern, die in den Turmmantel eingearbeitet sind, nach oben getragen wird. Dadurch entfällt eine sonst notwendige starre Konstruktion und der Turm kann als preiswerter flexibler Schlauch (Skizzen 2.1 bis 2.4) mit großer Höhe ausgebildet werden0 Da im Turm des Aufwindkraftwerkes stets ein Unterdruck gegenüber dler Atmosphäre herrscht, muß der Schlauch als sogenannter "Saugschlauch" ausgebildet werden. Hierzu sind verschiedene Varianten möglich.Therefore a tower is proposed here, characterized in that that its weight is carried by a tethered balloon or by buoyancy gas chambers, which are in the tower jacket are incorporated, is carried upwards. This eliminates one otherwise necessary rigid construction and the tower can be more flexible than cheaper Hose (sketches 2.1 to 2.4) with a great height 0 Since in the tower of the There must always be a negative pressure in relation to the atmosphere in the updraft power plant the hose can be designed as a so-called "suction hose". There are various options for this Variants possible.

h Skizze 2.1 werden einzelne zylindrische Ringe (Torus ) übereinander angeordnet und miteinander zu dem Turmschlauch verbunden. Das Ringinnere wird mit Gas ( Helium ) gefüllt und damit der Ring selbst zum Auf triebskörperO Entsprechend Skizze 2.2 werden die Ringe durch zwei Turmschläuche mit Zwischenstegen ersetzt. Entsprechend Skizze 2.3 lassen sich auch einzelne Hohlwülste auf die Schlauchfolie des Turmes aufschweißen oder aufkleben. Hier können die Wülste mit Gas gefüllt werden, wobei die Dichte des Gases im Mittel auch wieder leichter als die Luft der Atmosphäre sein muß. Wählt man die Versteifung des Turmschlauches in Form von Ringen oder einer Schraubenfeder wie bei "Feuerwehr-Saugschläuchen" (Skizze 2.4 , so muß der gesamte Auftrieb für den Turm von dem ringförmigen Fesselballon entsprechend Skizze 1.1 oder einem üblichen Fesselballon entsprechend Skizze 1.2 aufgebracht werden.h sketch 2.1, individual cylindrical rings (torus) are placed on top of each other arranged and connected to one another to form the tower hose. The inside of the ring is with Gas (helium) filled and thus the ring itself becomes the buoyant body In sketch 2.2 the rings are replaced by two tower hoses with intermediate bars. According to sketch 2.3, individual hollow beads can also be placed on the tubular film of the tower weld or glue on. Here the beads can with Gas are filled, the density of the gas on average also being lighter than must be the air of the atmosphere. If you choose the stiffening of the tower hose in In the form of rings or a helical spring as in "fire brigade suction hoses" (sketch 2.4, all of the buoyancy for the tower must come from the ring-shaped tethered balloon according to sketch 1.1 or a conventional tethered balloon according to sketch 1.2 be applied.

Damit das Aufwindkraftwerk nicht nur von der Sonne nenergie aufgewärmte Luft verarbeiten kann, sondern auch Windenergie, ist der Fesselballon so angeordnet, daß er das obere Schlauchende des Turmes wie eine Windhutze ausformt und stets in die Lee-Richtung zum Wind dreht (Skizze 1.1. und 1 2 )o Das Unterdruckfeld hinter dem oberen Schlauchende induziert einen Aufwind im Turm, dessen Energie von der Turbine verarbeitet wird.So that the updraft power plant was not only warmed up by the sun's energy Can process air, but also wind energy, the tethered balloon is arranged so that it forms the upper end of the tube of the tower like a scoop and is always in the leeward direction to the wind turns (sketch 1.1. and 1 2) o The negative pressure field behind the upper end of the hose induces an updraft in the tower, the energy of which is derived from the Turbine is processed.

Entsprechend der Stärke des Windes kann die Höhe des Turmes auch reduziert werden, so daß der Turm nicht für Orkane dimensioniert werden muß. Gerade bei sehr hohen Türmen spielt dieser Punkt eine große Rolle, da bei 500 bis 1000 m hohen Türmen die Gefahr einer Zerstörung bei zu starkem Wind recht groß ist. Außerdem muß während eines Sturmes auch bei festen Türmen die Turbine abgeschaltet werden, da sie sonst überlastet wird. Eine Reduzierung der Betriebsdauer ergibt sich deshalb bei den Schlauchtürmen gegenüber festen Türmen nicht.Depending on the strength of the wind, the height of the tower can also be reduced so that the tower does not have to be dimensioned for hurricanes. Especially with very high towers, this point plays an important role, as with 500 to 1000 m high towers the risk of destruction if the wind is too strong is quite high. Also must during In the event of a storm, the turbine must be switched off even in the case of fixed towers, otherwise it would is overloaded. A reduction in the operating time therefore results in the No hose towers compared to fixed towers.

Am äußeren Rand des Vordaches, dort wo die Luft unter das Vordach strömt, sollen Leitvorrichtungen angeordnet werden, die den einströmenden Wind in Drehung versetzen ( Skizze 3 ) und damit verhindern, daß der Wind quer durch das Vordach weht und die aufgewärmte Luft nutzlos vergeudet wird. Dem einströmenden drallbehafteten Wind kann in der Turbine Energie entnommen werden. Er verstärkt den Aufwind im Turm.At the outer edge of the canopy, where the air is under the canopy flows, guiding devices should be arranged to keep the incoming wind in Shift the rotation (sketch 3) and thus prevent the wind from crossing the The canopy blows and the heated air is uselessly wasted. The incoming Swirling wind can extract energy from the turbine. He strengthens the updraft in the tower.

Nach dem gleichen Prinzip soll auch das Vordach des Aufwindkraftwerkes durch gasgefüllte Folienschläuche (Skizze 4.1 und 4.2 ) oder durch eine gasgefüllte Doppelfolie (Skizze 4.3 ) getragen werden. Damit entfallen die aufwendigen Stützkonstruktionen, da die Halteseile nur Zugkräfte aufzunehmen brauchen können sie sehr geringe Querschnitte erhalten, Die Momente aus der horizontalen Belastung wie Druckdifferenzen, Schnee und Regen nehmen die Schläuche auf, so daß hier überhaupt keine zusätzliche Versteifung notwendig ist. Da aufgrund der Strömungsverhältnisse unter dem Vordach ein geringerer Druck als in der Atmoshäre herrscht, müssen die Schläuche nicht nur das Gewicht des Vordaches tragen, sondern auch noch den verminderten Auftrieb ausgleichen. Dies bereitet jedoch keine Schwierigkeiten. Dieses Prinzip eignet sich auch für selbstttragende Hallen, Gewächshäuser, Montage-,Messe-, Reit-, Tennis-und andere Sporthallen.The canopy of the updraft power plant should also follow the same principle by gas-filled foil tubes (sketch 4.1 and 4.2) or by a gas-filled one Double foil (sketch 4.3) can be worn. This eliminates the need for complex support structures, since the holding ropes only need to absorb tensile forces, they can have very small cross-sections get the Moments from the horizontal load such as pressure differences, Snow and rain take on the hoses, so no additional ones at all Stiffening is necessary. Because of the flow conditions under the canopy The hoses don't just have to have a lower pressure than the atmosphere carry the weight of the canopy, but also compensate for the reduced lift. However, this does not cause any difficulties. This principle is also suitable for self-supporting halls, greenhouses, assembly, exhibition, equestrian, tennis and others Sports halls.

Der Gasverlust durch Diffusion durch die Folie muß beim Turm und Vordach ständig ausgeglichen werden. Er ist jedoch gering. Derartige Leichtbauwerke lassen sich leicht montieren und demontieren. Sollen sie längere Zeit nicht genutzt werden, so kann man das Gas ablassen. Das Bauwerk legt sich dann auf den Boden. Zur Wiederverwendung ist es lediglich erneut aufzublasen.The gas loss by diffusion through the foil must be in the case of the tower and canopy be constantly balanced. However, it is minor. Let such lightweight structures easy to assemble and disassemble. Should they not be used for a long time, so you can let off the gas. The structure then lies on the ground. For reuse it is simply inflated again.
