Abstract
Gruson’s Fahrpanzer is a remarkable example of the military-technological changes occurring in the 19th century. It is a small and movable armour carriage for guns, i. e., an artillery piece shielded by armor. It was invented by Hermann Gruson and Maximilian Schumann and exported around the world. Even though the technical data had been documented extensively at the time, knowledge about the materials used and their mechanical properties have not survived. For this paper, one of Gruson’s Fahrpanzers was analyzed for the first time through materials science. The hypothesis that Gruson used his famous chilled cast iron for the Fahrpanzer could thus be refuted.
Kurzfassung
Der Gruson’sche Fahrpanzer ist ein bemerkenswertes Beispiel für die militärtechnologischen Umbrüche des 19. Jahrhunderts. Es handelt sich dabei um eine kleine und transportable Panzerlafette, also ein mit einer Panzerung umgebenes Geschütz. Diese Erfindung von Hermann Gruson und Maximilian Schumann wurde weltweit exportiert. Während die technischen Daten bereits zur damaligen Zeit umfassend dokumentiert wurden, gibt es keine Kenntnisse über die verwendeten Materialien und deren mechanische Eigenschaften. Im Rahmen der vorliegenden Arbeit wurde der Fahrpanzer erstmals werkstofftechnisch untersucht. Die Behauptung, dass für den Fahrpanzer der berühmte Gruson’sche Hartguss verwendet wurde, konnte so widerlegt werden.
