Abstract
Die Erfindung betrifft das Flugwesen, insbesondere den Aufbau von Luftschraubenblaettern und laeszt eine Verlaengerung der Sollbetriebszeit des Blattes zu. Das zusammengesetzte Luftschraubenblatt besteht aus dem Schaufelblatt 1 aus Plast mit dem geschichteten Holm 2, welcher von dem Metallbuegel 12 umschlossen wird, die mit dem konischen Blattschaft 3 aus Metall verbunden und mit in Richtung des Schaufelblatts 1 abnehmendem Durchmesser ausgefuehrt sind, und mit ringfoermigen Bunden 5, dabei ist das Blatt mit der in den Holm 2 eingelegten Einlage 11 aus Plast ausgestattet, und der Blattschaft 3 aus Metall ist mit der flachen Lamelle 4 ausgefuehrt, die in der Einlage 11 angeordnet ist, dabei sind die ringfoermigen Bunde 5 mit konischen Auflageflaechen und mit Hinterschneidungen 7 ausgefuehrt, die mit den Randboegen 8 der Schichten 9 des Holms 2 in Kontakt stehen, wobei der Holm 2 mit Gurten 10 mit einer Bewehrung ausgestattet ist, die zwischen den Schichten 9 des Holms 2 im Bereich der ringfoermigen Bunde 5 angeordnet sind. Die Schaufel ist mit der Zwischenlage 13 aus einem Elastomer versehen. Fig. 1The invention relates to flying, in particular the construction of Luftschraubenblaettern and promotes a prolongation of the desired operating time of the sheet. The composite propeller blade consists of the blade 1 made of plastic with the layered spar 2, which is enclosed by the metal bracket 12, which are connected to the conical blade shaft 3 made of metal and executed with decreasing in the direction of the blade 1 diameter, and ringfoermigen with coils. 5 , while the sheet is equipped with the inserted into the spar 2 insert 11 made of plastic, and the blade shaft 3 made of metal is executed with the flat blade 4, which is arranged in the insert 11, while the ringfoermigen coils 5 with conical Auflageflaechen and with undercuts 7, which are in contact with the marginal ridges 8 of the layers 9 of the spar 2, the spar 2 being provided with straps 10 with a reinforcement arranged between the layers 9 of the spar 2 in the region of the annular coils 5. The blade is provided with the intermediate layer 13 of an elastomer. Fig. 1
