| Tütenquerschnitt sleeve-shaped cross-sectional area (of control tube) Explanation: Deren Steuertüte ist am Rotorkopf kardanisch gelagert, um den Schlag- und den Schwenkfreiheitsgrad zu ermöglichen; außerdem ist in diese Lagerung noch ein Elastomer-Schwenkdämpfer integriert. Sivaneri und Chopra (1984) haben eine FEM-Analyse entwickelt, um die aeroelastische Stabilität zu berechnen. Jeder der flexiblen Blatthalsholme und auch die Steuertüte werden dabei als einzelne elastische Balken modelliert und die Kompatibilitätsbedingungen an der Anschlussstelle erfüllt. : Abb. 9.4 zeigt eine typische Konfiguration eines lagerlosen Rotors mit einem biege- und torsionsweichen Blatthals, der bis etwa 20% des Radius reicht. Dort wird er mit der statten Steuertüte verbunden und der profilierte Bereich des Blattes beginnt. https://books.google.de/books?id=WwZ0DwAAQBAJ&pg=PA352&lpg=P... Bei einem Steuertütenlager eines Hubschrauberheckrotors wird der Gurt in der Steuertüte zwischen zwei gegenüberliegenden Federelementen gehalten. Regarding the control cone bearing of a helicopter tail rotor, the chord is retained in the control cone between two opposing spring elements. https://context.reverso.net/translation/german-english/Steue... Hier ist das Steuertütenlager zu sehen (vor allem in Fig. 3 und 4): https://patents.google.com/patent/EP2246258B1/de Die Erfindung betrifft ein Rotorblatt für einen lagerlosen Rotor eines Hubschraubers, wobei das Rotorblatt im Bereich zum Rotorkopf hin und in Rotorblattlängsrichtung einen Flexbeam mit integriertem schlag-, schwenk- und torsionsweichen Bereichen besitzt, der am Rotorkopf befestigt ist und der Flexbeam von einer Steuertüte umhüllt ist und die Steuertüte in einem Übergangsbereich zwischen Flexbeam und auftrieberzeugendem Blatt befestigt ist und Dämpfungselemente angeordnet sind zur Dämpfung des rotierenden Rotorblatts in der Schwenkebene. http://www.patent-de.com/19991209/DE19915085A1.html Anmelder ist die gleiche Person, Kuntze-Fechner, Gerald, 83666 Waakirchen, DE. Auch die folgenden Patente stammen von ihm: ( 54) Rotor blade with control tube Rotorblatt mit Steuertüte Pale de rotor dotée d’un tube de commande. Description [0001] The invention relates to a system comprising a rotor blade in a fibre-reinforced composite design, and a separate sleeve-shaped control tube, in particular for a tail rotor or a rotary wing aircraft or helicopter. … The control tube or control sleeve comprises an essentially hollow-cylindrical shaft for receiving a tension-torque-transmission element and an also hollow tie section to tie the control tube to the rotor blade by attaching it to its coupling section. https://patentimages.storage.googleapis.com/dd/38/f5/ff92388... Rotor blade in flat design Apr 6, 2010 - Airbus Helicopters Deutschland GmbH A rotor blade (1), in particular of a main rotor of a rotary-wing aircraft, made of fiber-reinforced plastic includes a blade section (10) and a connecting section (12) for fastening the rotor blade (1) to a drive device (18) which includes a sleeve-shaped connecting device (14), is further developed in that the connecting device (14) includes flat fiber layers (S1 to S18) running substantially in the plane of extension of the connecting section (12). : This comprises a blade section and a connecting section for fastening the rotor blade to a drive device. The connecting section comprises a sleeve-shaped connecting device and lies at the end of the rotor blade opposite to the blade tip and therefore facing a drive axis. It connects the rotor blade at least indirectly to the drive device. For this it comprises at least one sleeve-shaped connecting device, for example, for a bolt connection. https://patents.justia.com/patent/8926288 Rotor blade with control tube Oct 11, 2010 - Eurocopter Deutschland GmbH A system comprising a rotor blade (1), in particular of the tail rotor of a rotary wing aircraft, in a fiber-reinforced composite design, with a blade section (5) and with a coupling section (9) for attaching the rotor blade (1) to the hub of a drive device, and comprising a separate sleeve-shaped control tube (40) with an essentially hollow-cylindrical shaft (41), with an also essentially tubular tie section (56) to tie the control tube (40) to the rotor blade (1) by sliding it onto its coupling section (9), is improved in that the coupling section (9) of the rotor blade (1) and the tie section (56) of the control tube (40) comprise a cross-sectional shape for positive-locking interconnection of the rotor blade (1) and the control tube (40). https://patents.justia.com/patent/8662847 ROTOR BLADE IN FLAT DESIGN Apr 6, 2010 - EUROCOPTER DEUTSCHLAND A rotor blade (1), in particular of a main rotor of a rotary-wing aircraft, made of fibre-reinforced plastic includes a blade section (10) and a connecting section (12) for fastening the rotor blade (1) to a drive device (18) which includes a sleeve-shaped connecting device (14), is further developed in that the connecting device (14) includes flat fibre layers (S1 to S18) running substantially in the plane of extension of the connecting section (12). : Description The invention relates to a rotor blade, in particular of a main rotor of a rotary-wing aircraft or helicopter, made of fibre-reinforced plastic. This comprises a blade section and a connecting section for fastening the rotor blade to a drive device. The connecting section comprises sleeve-shaped connecting device and lies at the end of the rotor blade opposite to the blade tip and therefore facing a drive axis. It connects the rotor blade at least indirectly to the drive device. For this it comprises at least one sleeve-shaped connecting device, for example, for a bolt connection. The rotor blade more favourably has two sleeve-shaped connecting devices which are disposed adjacent to one another in the plane of rotation of the blade since tilting moments of the blade from its forward travel or as a result of its inertia can be absorbed. https://patents.justia.com/patent/20100303628 cross section auch [ING.][TECH.] der Querschnitt Pl.: die Querschnitte section der Querschnitt Pl.: die Querschnitte transverse section der Querschnitt Pl.: die Querschnitte profile der Querschnitt Pl.: die Querschnitte width der Querschnitt Pl.: die Querschnitte cross-sectional area [TECH.] der Querschnitt Pl.: die Querschnitte https://dict.leo.org/englisch-deutsch/Querschnitt |
