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： Shear transfer elements can be formed by winding or weaving unidirectional fibers on a support structure. In a winding operation the support structure consists of two intersecting planes of winding mandrels with the planes arranged in angularly spaced relation. Each plane has two pair of mandrels with the mandrels in each pair located on the opposite sides of the line of intersection between the two planes. After the fibers are wound on the mandrels, each mandrel is axially disposed in the opposite direction relative to the other mandrel in the pair and also to the adjacent mandrel in the other pair in the same plane. Next, the fibers are pressed to form the shear transfer element. In a weaving operation, the support structure consists of a pair of pivotally interconnected frames. The fibers are woven onto holders on the sides of each frame extending parallel to the pivot axis of the frames. After placement of the fibers on the frames, the frames are pivoted apart and the fibers are pressed to form the shear transfer element.

摘要： The rotor blades or wings of the present helicopter rotor structure are interconnected by tension or carrier bars so that diametrically opposite rotor blades or wings form a pair. The tension bars are substantially stiff against bending, but permit some bending. The blade angle bearings are movable in the blade flapping direction, as well as in the blade lead-lag direction. At least one blade angle bearing of a pair of such bearings permits an axial movement of the respective tension or carrier bar, whereby the latter is able to take up bending loads.

摘要： The blades or wings of a rotary wing aircraft are secured to the rotor headn a non-rigid manner by means of a carrier bar, however, without any flapping hinges and without any lagging hinges. The carrier bar is supported on the rotor head. The connection of each wing to the respective end of the carrier bar is such, that the longitudinal wing axis is excentrically displaced relative to the central longitudinal axis of the carrier bar in the direction in which the forces of the air are effective. The displacement or spacing between the two axes is such that at least a partial compensation of the occurring bending moments is achieved.

摘要： A rotor blade has a neck section which connects the blade proper to a rotoread at the blade root. The neck section is flexible against bending in the lead-lag direction and in the flapping direction. A carrier member is located alongside or inside the neck section but spaced from the neck section. The carrier member is resistant against bending at least in the lead-lag direction or in the flapping direction. The carrier member is rigidly connected at its one end to the blade proper. A layer of a damping material is operatively interposed between the carrier member and the neck section, preferably at the blade root end of the neck section, whereby blade vibrations preferably in the lead-lag direction are damped and substantially prevented from entering into the rotor head.

Such rotor shall have a simple structure and a small structural weight while simultaneously having a high operational reliability. To this end the rotor hub comprises upper and lower support or carrier plates made of a fiber compound material arranged in such a manner that the fibers extend substantially radially. The upper and lower support plates are spaced from each other by thrust arms or lands and the blade angle bearings are supported between the carrier plates of a fiber compound material.

摘要： Resilient drive means for a helicopter rotor blade. The rotor blade is pivotally supported on a stub shaft which is in turn supported on the rotor hub. First means are fixed to the rotor blade and second means fixed to the stub shaft with resilient and adjustable means positioned therebetween for controlling the angular relationship between the rotor blade and the stub shaft. In this embodiment, said first means comprise a shoulder which projects from the rotor blade and the second means comprise a rectangular hollow frame which is fixed to the stub shaft. The shoulder projects into the hollow frame. Threaded means acting through resilient means holds the first and second means in selected pivotal adjustment with respect to each other but the resilient component thereof permits sufficient slight lead lag movement therebetween as to effect damping of the lead lag mode of the rotorblade. The adjustment capability permits sufficient adjustment of the blade with respect to the hub to ensure desired balance between the several blades of a given rotor.

摘要： The present hingeless rotor system for helicopters has carrier spars or b each of which is subdivided into three functional sections substantially forming the blade neck connecting the lift producing portion of the respective rotor blade to the rotor mast. The carrier spar sections form a single structural blade neck member extending for about two tenths of the rotor radius from the rotor mast to the lift producing blade portions. About one half of the length of the blade neck adjacent to the rotor mast form the connecting zone proper. The spar sections comprise bands forming respective loops in the connecting zone proper. Two of the band loops are connected one above the other and a third band loop is displaced in the direction of rotation of the rotor from the first mentioned band loops. The third band loop is releasably connected to the rotor mast to allow a folding of the respective rotor blade. The spar sections are interconnected by shear resistant bridging webs having a T- or X cross-section.

摘要： The present rotor structure for rotary wing aircraft, such as helicopters,s constructed to minimize the mass unbalance which normally occurs due to the lead-lag of the rotor blades or wings. For this purpose all the bearings supporting the rotors on the rotor heads are constructed as bearings permitting an axial movement of the tension bars which interconnect the wings of a pair of wings. In addition, the wing interconnecting bars are bending-resistant and connected with each other at their crossing point by a centering device which is freely movable in the rotor plane and relative to the rotor head. The connection of the bars by the centering device is rigid in the longitudinal, axial direction of the tension bars.
