摘要： A rotor for a rotary wing aircraft includes a rotor head and an even number of rotor blades arranged in pairs about the rotor head. The rotor blades of each pair are located diametrically opposite each other and each blade has a root end positioned radially inwardly toward the head. Bearings carried by the rotor head pivotally support each of the rotor blades. A torsionally elastic connection member extends between and connects the roots of a pair of rotor blades, and the connection member is mounted at its longitudinal center in the rotor head for pivotal movement about its longitudinal axis.

摘要： The blade angle of the blades is adjustable in a rotor for a rotary wing craft by a lever mechanism (13, 14 or 41, 42) secured to the radially inner end of an extension bushing (7; 7.1) or shaft (43). The extension bushing (7; 7.1) or shaft (43) is connected with its radially outer lever (15 or 44) to the blade root (2) or a blade root mounting (39, 50) of a rotor blade in an angular position adjustable manner for adjusting the tracking of the blades. The bushing (7; 7.1) or shaft (43) is adjustable in its angular position relative to the blade root (2) by adjustment screws cooperating with a free end of the lever (15 or 44) which reaches into a gap between two of such adjustment screws (16 or 45) cooperating with counter nuts (17 or 46). By adjusting the angular position of the bushing or shaft with the screws it is possible to assure a uniform tracking among all the blades of a multiblade rotor. Such uniform tracking is desirable if the blades of a rotor are to rotate in the same plane.

摘要： In a rotor for a rotary wing aircraft, an integral central headpiece supps the rotor blades. The headpiece consists of two plates interconnected by a centrally arranged distance member. Each plate has a similar star-shape with at least four angularly spaced point-like arms. Each plate is formed of a number of superposed layers with each layer containing continuous loops extending in the direction of the point-like arms. At least one loop extends from one point-like arm into another diametrically opposite point-like arm. Others of the loops, located in the other point-like arms, extend radially outwardly from the loop extending through the two point-like arms. The headpiece consisting of the plates and distance member, is a unitary or integral structure.

摘要： The blade angle of the blades of a rotary wing aircraft is adjusted by a control rod (5) inside the hollow rotor head operating a control shaft (8) extending radially out of the rotor head in axial alignment with the blade angle adjustment axis. The adjustment movement of the shaft (8) is transmitted to the respective blade (3.3) by a yoke (11, 12) and a torsion-stiff sleeve (7) which bridge the blade root (3.1) and the torsion yielding blade neck (3.2) respectively. The blade root (3.1) is connected to the rotor hub (1) by a forked member (2) through which a portion (11) of the yoke extends for connection to the control shaft.

摘要： The present four-blade rotor is made up of two blade pairs, each blade pairaving two rotor blades arranged diametrically opposite one another. The blades of each blade pair are coupled to each other by means of a coupling loop for taking up centrifugal forces produced by the rotation of the blades. The present rotor system also has a centering device including a centering body and tension straps for each coupling loop. The tension straps connect the respective loop end to the centering body whereby the two coupling loops may be centered in the rotor head practically without play and without substantially limiting the free movement of the coupling loops.
摘要翻译：本发明的四叶片转子由两个叶片对构成，每个叶片对具有彼此直径相对设置的两个转子叶片。每个叶片对的叶片通过联接回路彼此联接，以吸收由叶片的旋转产生的离心力。本转子系统还具有定心装置，其包括用于每个联接回路的定心体和张力带。张力带将相应的环端连接到定心体，由此两个耦合回路可以在转子头部中实际上不起跳而不会基本上限制耦合回路的自由运动。

摘要： The present hingeless rotor structure, especially for rotary wing aircraft,omprises at least one pair of rotor blades, whereby the blades of a pair are arranged diametrically opposite each other. The blades are secured to a rotor head for proper blade angle adjustment. Each blade has its root or radially inner end secured in a blade root sleeve which in turn is held in a respective blade angle bearing bushing. The blades of a pair are interconnected by a tension resistant, torsionally yielding member. One bearing which is pressure loadable in the direction of the longitudinal blade axis is provided for each blade pair between one of the respective blade root sleeves and the corresponding blade angle bearing bushing. The tension resistant, torsionally yielding member is capable of a certain stretching or elongation during operation. In order to compensate for such an elongation, the tension resistant, torsionally yielding members are installed in such a manner that in the rest or non-rotating condition of the blades, the center is radially displaced from the axis of rotation of the rotor head toward the respective pressure loadable bearing by one half of the length of said elongation.
