Abstract: A preferred embodiment of a pylon has six pylon mounting links for mounting the pylon to an airframe. Each link is considered ''near-rigid'' and has a spherical-bearing rod-end on both ends such that the link can only transmit axial loads. At least one of the links has a mass carried within the link and selectively moveable by an actuating means along the axis of the link in an oscillatory manner for attenuating vibrations traveling axially through the link. The actuating means may be an electromechanical, hydraulic, pneumatic, or piezoelectric system. By mounting each link in a selected orientation relative to the other links, the actuating means may be operated in a manner that attenuates axial vibration that would otherwise be transmitted through the link and into the airframe.
Abstract translation: 塔的优选实施例具有用于将吊架安装到机身上的六个安装链。 每个连杆都被认为是“接近刚性”,并且在两端都有一个球形轴承杆端,使得连杆只能传递轴向载荷。 链节中的至少一个具有在链节内承载的质量,并且可以通过致动装置沿着连杆的轴线以振荡方式选择性地移动,以便衰减轴向穿过连杆的振动。 致动装置可以是机电,液压,气动或压电系统。 通过将每个链节相对于其它连杆安装在选定的方向上,致动装置可以以衰减轴向振动的方式操作,否则轴向振动将通过连杆传递到机身中。

Abstract: PROBLEM TO BE SOLVED: To provide a rotor hub suitable for use under the limitation on the composition of a prop rotor aircraft. SOLUTION: The hub 10 contains a constant velocity universal joint 50 in the same plane as a yoke 12. Torque is transmitted from a shaft to a blade through the constant velocity universal joint, hub plates 14 and 16 installed on the joint, and the yoke installed on the hub plates. By providing all elements on a plane arrangement structure, the height of a hub assembly is lowered substantially more than a traditional formation. The hub itself comes in the same plane as the yoke, and torque is transmitted more efficiently from a mast to a rotor.

Abstract: PROBLEM TO BE SOLVED: To prevent exfoliation between layers in middle faces of a bent member made of composite material such as a yoke of a main rotor of a helicoputer comprising laminated composite material to increase its strength and fatigue life. SOLUTION: An exposed edge surface 24 of the bent member made of the composite material is provided with edge members 51, 53. Each of the edge members 51, 53 includes an innermost layer 57 mounted on the edge surface 24, an outermost layer 59 mounted on the innermost layer 57, and plural internal layers 55 disposed between the innermost layer 57 and the outermost layer 59.

Abstract: PROBLEM TO BE SOLVED: To maintain safety of an aircraft, by using distortion gage which directly measures distortion by preload of down stop assembly. SOLUTION: When a trough part 117 is warped, a distortion due to down stop load is directly sensed by sensor modules 161. Each of the sensor modules 161 generates a signal in proportion to a down stop preload due to distortion by preload. an average preload measure value is found by a plurality of preload measurements and is processed, whereby comparison with respect to a predetermined allowable range is carried out. Further, the predetermined allowable range is selected such that an appropriate preload is present between a tilt rotor assembly and a wing in order to maintain safety of an aircraft while avoiding overload at any part of structure of the aircraft. By this constitution, the sensor module 161 and a distortion gage are used for directly measuring combined static and dynamic loads varying inside a tilt rotor aircraft.

Abstract: The device is configured for moving a fluid within a gearbox. In one illustrative embodiment, the device includes a base portion coupled to a rotatable member within the gearbox. An inlet portion of the device is configured to draw the fluid from a reservoir portion of the gearbox. The device is configured to utilize a centrifugal force for moving the fluid from the inlet portion toward the base portion along an interior surface of a conical portion. In another illustrative embodiment, the device includes a conical portion having an external threaded portion configured to capture a fluid during a rotation of the device. In such an embodiment, the threaded portion is configured to utilize a centrifugal force for moving the fluid captured by the threaded portion along an exterior surface of the conical portion.
