摘要： A method of locating position on a component includes engaging a template with a component and marking a location on the component using marking features of the template. Marking a location can include marking a plurality of locations on the component using a plurality of respective marking features of the template. Each marking feature of the template can include a corner formed where at least two edges meet on the template. Marking each respective location on the component can include marking two line segments that cross at an intersection point, wherein the two line segments follow the edges of the template at each respective corner, to mark the respective location on the component at the intersection of the two respective line segments. For example, marking each location can include marking a center point location for a strain gage, as well as the horizontal and vertical orientation.

摘要： A method of forming a balanced rotor blade assembly includes measuring a weight of a plurality of sub-components of the rotor blade assembly excluding a core. A configuration of a core of the rotor blade assembly is determined. In combination, the core and the plurality of sub-components achieve a target weight distribution and moment. The core is then fabricated and assembled with the plurality of sub-components to form a rotor blade sub-assembly.

摘要： A pressure tool for rotor blade repair including a mobile support system including a support surface, a first bladder support assembly including a first inflatable bladder fixedly mounted to the support surface, a second bladder support assembly including a second inflatable bladder pivotally mounted relative to the support surface, and an activation mechanism operatively coupled to the second bladder support assembly. The activation mechanism is operable to selectively shift the second bladder support assembly relative to the first bladder support assembly. A fluid delivery system is operable to direct a fluid into each of the first inflatable bladder and the second inflatable bladder.

摘要： A portable computerized device for an aircraft control system includes an input system for inputting commands, a device display for displaying information on the computerized device, a processor, a wireless communication module, and a non-transitory computer readable medium comprising computer executable instructions, the computer executable instructions configured to cause the processor to perform a method. The method can include detecting whether the portable computerized device is in a cockpit state such that the portable computerized device is in and/or docked to an aircraft cockpit or if the portable computerized device is in a remote state such that the portable computerized device is not in an aircraft cockpit or is not docked to an aircraft cockpit. If the portable computerized device is determined to be in a remote state, the method includes operating the remote device in a remote mode. If the portable computerized device is determined to be in a cockpit state, the method includes operating the device in a local mode.

摘要： An aircraft rotor system includes a rotating pitch change shaft which rotates about an axis, a translating element disposed within the rotating pitch change shaft and movable along the axis and a pitch change bearing assembly which transfers movement of the translating element to the pitch change shaft. The pitch change bearing assembly includes a primary bearing and a secondary bearing coupled to the rotating pitch change shaft via the translating element when the primary bearing is in a first mode. A thrust shoulder is coupled to the translating element. The thrust shoulder is movable into engagement with the secondary bearing in response to failure of the primary bearing such that in a second mode, movement of the translating element is primarily transferred to the pitch change shaft via the secondary bearing.

摘要： A rotary-wing aircraft and system for flying a rotary-wing aircraft. The aircraft includes a servo system for actuating a rotor of the aircraft. A hydraulic system provides hydraulic power to the servo system, and a sensor measures a parameter of the hydraulic system. A processor determines a condition of the hydraulic system from the parameter and enforces an effective flight envelop based on the condition of the hydraulic system in order to fly the aircraft within the effective flight envelope.

摘要： A method of determining structural health of an assembly includes determining a Margin of Safety (MSH) value for at least one of a plurality of components in the assembly when the assembly is healthy. The method includes determining if damage to the assembly has occurred. If damage to the assembly has occurred, the method includes determining a Margin of Safety (MSD) value for at least one of the plurality of components in the assembly when the assembly is damaged. The method includes determining a Structural Health Index (SHI) of the assembly based on the MSD value for the at least one undamaged component.

摘要： A bond fixture includes a frame defining a chamber for receiving a component. At least one bladder assembly is connected to the frame. The at least one bladder assembly includes a pad for contacting the component. A position of the pad relative to the component is controlled by a pressure of the bladder assembly. A caul assembly is adapted to thermally couple to the component to heat a localized portion of the component.

摘要： A spherical bearing which extends from and connects to a deformable component includes an outer member and an inner member. The inner member is pivotable relative to the outer member about an axis. The inner member has an opening formed therein that defines a plurality of coplanar contact surfaces shaped to accommodate and contact the component. The plurality of contact surfaces are movable to accommodate deformation of the component positioned within the opening.
