Radial vom Antriebskanal 11 ausgehend, sind 15 Schalen, nämlich der Außenschale 24 und der Innen-Luftleitungen 16 in einem Bereich kurz hinter dem schale 24 a. Radial umlaufend sind einer jeden Triebwerk und radiale Luftleitungen 17 im Bereich Gruppe von Streben 23, 23 α usw. Vertiefungen 26 des Luftschiffhecks angeordnet. Dabei können jeweils zugeordnet, die zur Grenzschichtbeeinflussung dienen, vier in einem rechten Winkel zueinander stehende Diese Vertiefungen 26 sind mit Abdeckungen verLuftleitungen 16,16 α usw. kurz hinter dem Antrieb 20 sehen, welche Luftschlitze aufweisen. Das soll in sowie Luftleitungen 17,17 α usw. in den Leitwerken Verbindung mit den F i g. 4 bis 7 erläutert werden, vorhanden sein. Diese radialen Luftleitungen erfüllen Die Gruppen der Hohlstreben 23, 23 a, 23 b usw. die Aufgabe, das Luftschiff zusätzlich zu den Heck- münden an ihren Enden in zugeordnete Rundspanten flössen und den Höhen- und Seitenrudern 18 und 18 b 27, 27 a, 27 b usw., von denen in F i g. 4 das Rundzu steuern, insbesondere das in der Luft stehende 25 spant 27 sowie die zugehörige Hohlstrebengruppe 23 Luftschiff zu manövrieren. Am Heck des Luftschiffes zu sehen sind. Zusätzlich zu diesen Rundspanten 27 ist vorgesehen, daß der zentrische Antriebskanal 11 sind noch Längsträger vorhanden, welche die Streben in mehrere Austrittsdüsen 22, 22 α aufgeteilt ist. in Längsrichtung des Luftschiffes verbinden. F i g. 4Starting radially from the drive channel 11, there are 15 shells, namely the outer shell 24 and the inner air ducts 16 in an area shortly behind the shell 24 a. Radially circumferential are each engine and radial air lines 17 in the area of the group of struts 23, 23 α , etc., depressions 26 of the airship stern. In this case, four are assigned which are used to influence the boundary layer and are at right angles to one another. These recesses 26 are provided with covers, air ducts 16, 16 α , etc., shortly behind the drive 20, which have air slots. That should be in and air lines 17,17 α , etc. in the tail units connection with the F i g. 4 to 7 are explained. These radial air ducts fulfill the task of the groups of hollow struts 23, 23 a, 23 b etc., in addition to the stern mouths of the airship at their ends into associated round ribs and the elevators and rudders 18 and 18 b 27, 27 a, 27 b etc., of which in Fig. 4 to steer the Rundzu, in particular to maneuver the 25 frame 27 standing in the air and the associated hollow strut group 23 of the airship. Can be seen at the stern of the airship. In addition to these round frames 27, it is provided that the central drive channel 11 are also longitudinal members, which the struts is divided into several outlet nozzles 22, 22 α . Connect in the longitudinal direction of the airship. F i g. 4th
