Abstract

The method of directly observing pressure combustion processes in deep seas makes it possible to observe combustion processes taking place under high environmental and even higher internal combustion pressures by means of video cameras and to use the data obtained directly to optimise burner nozzles or combustion chambers, for example. This direct use of the data obtained in the transparent test medium, which at the same time eliminates cooling and technical materials problems, saves valuable development time and costs.

Description

Bekannt sind Unterwasser-Simulationsanlagen zur Entwicklung von Unterwasserarbeiten, die speziell für die Offshore-Technik benötigt werden. ("GUSI", Hamburg) In diesen Druckbehältern wurden auch Schweißverfahren erprobt, wobei die Anwendungstechnik im Vordergrund stand und nicht die Beobachtung von Druckverbrennungsvorgängen.Underwater simulation systems for development are known of underwater work specifically for offshore technology are needed. ("GUSI", Hamburg) Welding processes were also tested in these pressure vessels, the application technology was in the foreground and not the Observation of pressure combustion processes.

Versuche mit einem Wasserstoff/Sauerstoff-Brenner in höheren Druckbereichen liegen nicht vor, da die Möglichkeit der Knallgas bildung im Versuchsbehälter bislang dem Versuch entgegenstand. Drücke, wie sie in dem oben zur Patentanmeldung anstehenden Verfahren und bei den Schmelzbohrverfahren nach DE 25 54 101 C2 sowie DE 37 01 676 A1 auftreten, könnten unter großräumigen, realistischen Bedingungen, wie in der Tiefsee möglich, in Druckbehältern nicht erzeugt werden.Try using a hydrogen / oxygen burner in higher Pressure ranges do not exist because of the possibility of oxyhydrogen education in the test container has so far been an obstacle to the experiment. Press as in the pending patent application above Process and in the melt drilling process according to DE 25 54 101 C2 and DE 37 01 676 A1 could occur under large-scale, realistic conditions as possible in the deep sea Pressure vessels are not generated.

Aufgabe dieser Patentanmeldung ist es, nicht direkt beobachtbare Druckverbrennungsvorgänge sichtbar zu machen, um die Brennstrahl form und deren Veränderung unter variablen Außendrücken und Brennstoff-Innendrücken zur Optimierung von z.B. Brennerdüsen oder Brennkammern zu studieren.The object of this patent application is not directly observable Pressure combustion processes to visualize the focal jet shape and its change under variable external pressures and Internal fuel pressures to optimize e.g. Burner nozzles or study combustion chambers.

Speziell für das oben genannte Schmelzbohrverfahren ist es Auf gabe dieses Prüfverfahrens, die Aufrechterhaltung der Brennvor gänge unter Außendrücken bis zu 1000 bar nachzuweisen und Daten zur Entwicklung von Schmelzbohrgeräten zu gewinnen, die selbst steuernd durch Regelung der Brenngasdrücke die optimale Bohr fortschrittsgeschwindigkeit einstellen. It is open especially for the melt drilling method mentioned above this test procedure, the maintenance of the firing gears under external pressures up to 1000 bar and data to develop melting drilling rigs that win themselves controlling the optimal drilling by regulating the fuel gas pressures set progress speed.

Gelöst wird diese Aufgabe dadurch, daß Brenner an einem Test gerüst so postiert sind, daß installierte Unterwasser- Videokameras von allen Seiten den Brennvorgang erfassen können. Das Testgerüst wird in entsprechende Tiefen abgesenkt und die Ergebnisse der Brennversuche werden über Monitoren im Forschungslabor direkt sichbar und für Simulationscomputer unmittelbar verwertbar.This task is solved by having Brenner carry out a test scaffolding are positioned so that installed underwater Video cameras can record the burning process from all sides. The test framework is lowered to the appropriate depths and the Results of the burning tests are monitored on the Research laboratory directly visible and for simulation computers immediately usable.

Die Brennstoffversorgung kann über Druckflaschenbündel oder nach dem "TUBE-COIL Sytem" s. P 39 14 617.0 ausgeführt werden, wobei die über die Leitungen des "TUBE-COIL Sytem" geführten Drücke ohne hohen Nutzspeicherverlust für den Brennvorgang zur Verfügung stehen, was vor allem für Tiefstversuche von Bedeutung ist.The fuel supply can be via pressure cylinder bundles or according to the "TUBE-COIL system" s. P 39 14 617.0 are executed, whereby those led over the lines of the "TUBE-COIL system" Press for the burning process without high usable memory loss Are available, which is particularly important for deep trials is.

Der Auftrieb der Versuchsanlage und die Veränderung der Gleich gewichtslage während der Brennperioden wird durch das Eigen gewicht der Anlage verhindert.The buoyancy of the pilot plant and the change in equals weight position during the burning periods is determined by the own weight of the system prevented.

Die Kühlung des Brenners wird vom Testmedium übernommen.The burner is cooled by the test medium.

Die Vorteile des Tiefsee-Testverfahren zur Simulation von Druckverbrennungsvorgänge liegen:The advantages of the deep sea test procedure for simulating Pressure combustion processes are:

1. in the visualization of the combustion processes and their direct acquisition via monitors and Data storage.
2. in the immediate use of data for computer simu lation and for torch optimization using CAD / CAM Process for machine tools on board passed on to the production of improved burners and for further burning tests during a test drive can be tested to the optimum.
3. in the use of the test medium as a coolant, whereby the solution of material problems not before Testing of test equipment is required.
4. in the time and cost savings that result from points 1 to 3 and that could especially accelerate the development of the melting drilling technology rapidly.
5. in carrying out a "feasibility study" the basic with relatively little resources technical feasibility e.g. the melting drilling technique can be demonstrated.
6. in the user application for all pressure combustion processes, especially in rocket technology and in combustion technology for vehicles powered by hydrogen.
