Description

Die Erfindung bezieht sich auf einen Gasgenerator für Auftriebssäcke von Wasserfahrzeugen nach dem Oberbegriff des Anspruchs 1.The invention relates to a gas generator for buoyancy bags of watercraft according to the preamble of claim 1.

U-Boote benötigen eine Schwimmblase für den normalen Betrieb, aber auch für den Fall eines Unfalls. Das bisherige System nach der EP 0 736 450 B1 mit den Merkmalen des Oberbegriffs des ersten Anspruchs hat den Nachteil, dass zwar sehr viel Gas in der Tauchzelle - produziert wird, dass dieses Gas durch das Leck der Tauchzelle aber entweichen kann. Das Boot wird zwar gehoben, beginnt aber sehr schnell wieder zu sinken und zwar dann unwiderruflich bis zum Grund der See. Dieser Vorgang wird dadurch verstärkt, dass das Gas sehr heiß in die Tauchzelle einströmt und dort - infolge seiner schnellen Abkühlung - noch mal sein Volumen verkleinert. Weitere Nachteile sind, dass dieses Gas explosionsfähig ist und seine Ausgangsstoffe ein starkes Fischgift sind.Submarines need a swim bladder for normal operation, but also in case of an accident. The previous system according to EP 0 736 450 B1 having the features of the preamble of the first claim has the disadvantage that, although a great deal of gas is produced in the immersion cell, this gas can escape through the leak of the immersion cell. The boat is lifted, but it begins to sink again very quickly and then irrevocably to the bottom of the lake. This process is intensified by the fact that the gas flows very hot into the immersion cell and there - due to its rapid cooling - again reduced its volume. Other disadvantages are that this gas is explosive and its starting materials are a strong fish poison.

Aufgabe der Erfindung ist es, ein Rettungssystem vorzuschlagen, dass o. g. Nachteile nicht aufweist.The object of the invention is to propose a rescue system that o. G. Disadvantages not.

Die Erfindung löst diese Aufgabe entsprechend den kennzeichnenden Merkmalen des Anspruchs 1.The invention solves this problem according to the characterizing features of claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Das vorgeschlagene System besteht aus einer Vielzahl von Modulen, die ihrerseits im wesentlichen aus einem aufblasbaren Sack und einem Gasgenerator bestehen. Da der Gasgenerator nur so viel Gas produzieren muss - da das Gas vom Sack gehalten wird - , dass der Sack in der größten Tiefe voll aufgeblasen wird, kann der Gasgenerator deutlich kleiner ausfallen als der aus der EP 0 736 450 B1 Bekannte. Allerdings verlangt dieses System eine relativ lange Blaszeit des Gasgenerators und relativ kaltes Gas (Verletzung des Sacks, Verkleinerung der Oberfläche durch Abkühlung).The proposed system consists of a plurality of modules, which in turn consist essentially of an inflatable bag and a gas generator. Since the gas generator only has to produce as much gas - because the gas from the bag is held - that the bag is fully inflated in the greatest depth, the gas generator can be significantly smaller than the known from EP 0 736 450 B1 Known. However, this system requires a relatively long blowing time of the gas generator and relatively cold gas (injury of the bag, reduction of the surface by cooling).

Weitere Vorteile sind:

  • Die Gasproduktionsrate ist bis zur Auslegungstiefe unabhängig vom Umgebungsdruck.
  • Das Gas ist kalt, weshalb auch durch Abkühlung kein Auftriebsverlust eintritt. Im Falle der Anwendung bei einem U-Boot ist gewährleistet, dass das U-Boot wenigstens eine halbe Stunde an der Wasseroberfläche gehalten werden kann. Somit besteht genügend Zeit, um die Mannschaft aussteigen zu lassen.
  • Weder die Ausgangsstoffe des Gassatzes noch seine Reaktionsprodukte sind explosionsfähig oder giftig.
  • Das benötigte Gasvolumen ist kleiner/gleich dem der Tauchzellen, d. h., man benötigt nur relativ kleine Gasgeneratoren - und ist dadurch in der Lage redundant zu arbeiten.
  • Das geringere Volumen und das geringere Gewicht des Systems erlauben es, die Auftriebseinheiten entsprechend dem deutschen Patent der Anmelderin, DE 197 52 498 C2 - an Fangleinen befestigt - in den Tauchzellen aufschwimmen zu lassen und den zur Verfügung stehenden Raum optimal zu nutzen.
Further advantages are:
  • The gas production rate is independent of the ambient pressure up to the design depth.
  • The gas is cold, which is why no loss of buoyancy occurs by cooling. When used with a submarine, it is ensured that the submarine can be kept at the water surface for at least half an hour. Thus, there is enough time to let the team drop out.
  • Neither the starting materials of the gas kit nor its reaction products are explosive or toxic.
  • The required gas volume is less than / equal to that of the immersion cells, ie, you only need relatively small gas generators - and thus it is able to work redundantly.
  • The lower volume and the lower weight of the system make it possible to float the buoyancy units according to the German patent of the applicant, DE 197 52 498 C2 - attached to suspension lines - to float in the dip tanks and to make optimal use of the available space.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Ein Gasgenerator 10 besteht aus einer zweistufigen Rohrhülse 12 mit einem Hoch- und einem Niederdruckraum 14, 16. Die beiden Räume 14, 16 sind durch eine Drossel 18 miteinander verbunden. In dem Hochdruckraum 14 befindet sich der gasliefernde Satz 20 und die Anzündung 22. Das in dem Hochdruckraum 14 erzeugte Gas, siehe die Pfeile 24 strömt durch die Drossel 18 in den Niederdruckraum 16. In diesem befindet sich in einem Abstand 26 eine Prallplatte 28 aus Graphit zur Gasumlenkung. Im Niederdruckraum 16 liegen hintereinander fünf Drahtkörbe 30 mit Sieben 33 und mit Granulat 32 eines ablativen Kühlsystems. Die Drahtkörbe 30 liegen spaltfrei an der Innenwand der Rohrhülse 12 an. Das Granulat 32 hat die Eigenschaft durch endotherme Reaktion das aus der Drossel 18 ausströmende und durch die Prallplatte 28 abgelenkte Gas, Pfeile 24, zu kühlen. Außerdem erzeugt das Granulat 32 zusätzlich Gas.A gas generator 10 consists of a two-stage tubular sleeve 12 with a high and a low pressure chamber 14, 16. The two chambers 14, 16 are connected by a throttle 18 with each other. In the high-pressure chamber 14 is the gas-supplying set 20 and the ignition 22. The gas generated in the high-pressure chamber 14, see the arrows 24 flows through the throttle 18 in the low pressure chamber 16. In this is located at a distance 26, a baffle plate 28 made of graphite for gas diversion. In the low pressure chamber 16 are five wire baskets 30 with sieves 33 and granules 32 of an ablative cooling system in a row. The wire baskets 30 are gap-free against the inner wall of the tube sleeve 12. The granules 32 have the property by endothermic reaction of the effluent from the throttle 18 and deflected by the baffle plate 28 gas, arrows 24 to cool. In addition, the granules 32 additionally generates gas.

Vorteilhaft wird durch die Prallplatte 28 sowie durch nachgeschaltete Siebe 33 und granulatfreie Zwischenräume 34 erreicht, dass eine Kanalbildung in den Drahtkörben 30 durch Zerstören des Granulats 32 nicht auftritt. Das Granulat 32 wird durch vollflächigen und gleichmäßig fortschreitenden Abbrand, entsprechend dem Querschnitt der Drahtkörbe 30 vollständig in Gas umgesetzt.
Die Drossel 18 bestimmt nicht nur den Volumenstrom des Gases sondern sorgt auch dafür, dass bis zu einer - einstellbaren - Höhe des, der Wassertiefe entsprechenden Außendrucks der Abbrand des Satzes 20 unabhängig vom Außendruck abläuft, d. h., von der Wasseroberfläche bis zur Auslegungstiefe ist die vom Gasgenerator 10 gelieferte Gasrate und Gasmenge konstant.It is advantageously achieved by the baffle plate 28 and by downstream sieves 33 and granulate-free spaces 34 that a channel formation in the wire baskets 30 by destroying the granules 32 does not occur. The granules 32 is completely converted into gas by full-surface and uniformly progressive burning, corresponding to the cross-section of the wire baskets 30.
The throttle 18 not only determines the volume flow of the gas but also ensures that up to a - adjustable - height of the water depth corresponding external pressure of the burnup of the set 20 is independent of the external pressure, ie, from the water surface to the depth of interpretation of the Gas generator 10 delivered gas rate and gas volume constant.

Zwischen den Drahtkörben 30 liegen Entspannungsräume 34. Diese dienen als Gasauffang- und Gasleiteinrichtungen. Sie dienen dazu, das Gas möglichst verlustarm so durch das Granulat 32 zu führen, damit durch die dabei entstehenden Reaktionen das Gas auf die gewünschte Temperatur heruntergekühlt wird.Between the wire baskets 30 are relaxation rooms 34. These serve as gas collecting and Gasleiteinrichtungen. They serve to guide the gas through the granules 32 with as little loss as possible, so that the gas is cooled down to the desired temperature by the resulting reactions.

Der Satz 20 befindet sich zusammen mit der schematisch dargestellten Anzündung 22 in der zylindrischen Hochdruckkammer 14. In eine Wand 38, die den Hoch- und Niederdruckraum 14, 16 voneinander trennt ist die Drossel 18 eingesetzt. Durch sie strömt das heiße Gas mit Schallgeschwindigkeit, M=1, im engsten Querschnitt in einen Verteilerraum 40 des Niederdruckraums 16.The set 20 is located together with the ignition 22 shown schematically in the cylindrical high pressure chamber 14. In a wall 38, which separates the high and low pressure chamber 14, 16 from each other, the throttle 18 is inserted. Through them, the hot gas flows at the speed of sound, M = 1, in the narrowest cross section in a distribution chamber 40 of the low-pressure chamber 16th

Das Gas tritt mit etwa 1000 °C aus der Drossel 18 aus. Nach dem Aufprall auf die Prallplatte 28 strömt das Gas großflächig in den ersten Drahtkorb 30 mit dem kühlenden und auch noch gaserzeugenden Granulat 32. Nach einer ersten endothermen Reaktion in dem ersten Drahtkorb 30 entspannt sich das Gas nach dem Querschnitt durch das erste Sieb 33 in dem ersten Entspannungsraum 34 gemäß einem Abstand 35 und tritt dann in den zweiten Drahtkorb 30.1 ein.The gas exits the throttle 18 at about 1000 ° C. After impact on the baffle plate 28, the gas flows over a large area in the first wire basket 30 with the cooling and also gas-generating granules 32. After a first endothermic reaction in the first wire basket 30, the gas relaxes after the cross section through the first sieve 33 in the first relaxation space 34 according to a distance 35 and then enters the second wire basket 30.1.

Die vorbeschriebenen Abläufe wiederholen sich bis zum letzten Entspannungsraum 34.5, der dem Volumen eines Gassackes 42 entspricht.The above-described processes are repeated until the last relaxation space 34.5, which corresponds to the volume of an airbag 42.

Der Gassack 42 mit einem Gasvolumen von 1 m3 ist an der Stirnseite 44 des Gasgenerators 10 über eine Flanschbefestigung 46 befestigt.The gas bag 42 with a gas volume of 1 m 3 is attached to the end face 44 of the gas generator 10 via a flange 46.

Gegenüberliegend ist ein Verteilersieb 28 über einen Flansch 50 befestigt.Opposite a distribution screen 28 is attached via a flange 50.

Der gasliefemde Satz 20 hat einen Durchmesser von 240 mm bei einer Höhe von 82 mm. Die Länge 11 des Gasgenerators beträgt 500 mm.The gas delivery set 20 has a diameter of 240 mm at a height of 82 mm. The length 11 of the gas generator is 500 mm.

Versuche ergaben, dass das aus der Drossel 18 mit etwa 1100 Grad Celsius ausströmende Gas am Verteilersieb 48 in einer Wassertiefe von 24 Metern eine Temperatur von etwa 75 °C aufweist. Das erzeugte Gasvolumen betrug hierbei 3,4 m3. Die sogenannte Blaszeit betrug 135,5.Tests have shown that the gas flowing out of the throttle 18 at about 1100 degrees Celsius has a temperature of about 75 ° C. at the distributor screen 48 at a water depth of 24 meters. The gas volume produced was 3.4 m 3 . The so-called blowing time was 135.5.

Die für das Gewebe des Gassackes vorgegebene Grenztemperatur von 100 °C wurde daher wesentlich unterschritten.The specified for the fabric of the airbag limit temperature of 100 ° C was therefore significantly below.

Die Temperatureinstellung des Gases am Verteilersieb 48 erfolgt in einfacher Weise über die Summe der Längen 52 des Granulats 32 in den jeweiligen Drahtkörben 30 - 30.4.The temperature setting of the gas on the distributor screen 48 is carried out in a simple manner over the sum of the lengths 52 of the granules 32 in the respective wire baskets 30-30.4.

Die Rohrhülse 12 weist einen kreisförmigen Querschnitt auf. Diese Querschnittsform ist nicht zwingend. Es kann jede beliebige Querschnittsform gewählt werden. The tube sleeve 12 has a circular cross-section. This cross-sectional shape is not mandatory. It can be chosen any cross-sectional shape.
