Abstract: This description relates to a strapped windshield assembly for a rotorcraft. In some implementations, the rotorcraft includes an airframe, a windshield, and a plurality of independent straps connected to the airframe and the windshield, the straps operative to move independently with respect to one another. The independent movement of the straps allow relative movement of portions of the windshield in response to a strike. In some implementations, the straps are spaced every 4-6 inches along an edge of the windshield. In some implementations, the straps are over an edge of the windshield. The straps can have a modulus of elasticity of 8-12 millions of pounds per square inch (MSI). The windshield can include polycarbonate material.

Abstract: In one aspect, there is provided a rotary blade movement system including a retaining member configured to receive a rotor blade, a graspable arm, and a coupling mechanism operable to removably couple the retaining member to the graspable arm. The rotor blade movement system is configured to enable a user to adjust the position of the rotor blade by moving the graspable arm. The coupling mechanism can be a ball and socket joint. In one aspect, there is a method of rotating a rotor blade using a rotary blade movement system.

Abstract: In one embodiment a computer system comprises a processor, a basic input/output system (BIOS) including logic instructions which, when executed by the processor, configure the processor to create a virtual AML device data structure, the data structure comprising a plurality of fields to hold arguments to a native firmware function, store at least one argument for the native firmware function in a register of the AML device data structure, store an entry point and a pointer value in a register of the virtual AML device data structure, and initiate an access request to a firmware access register in the AML device data structure.

Abstract: Covers on bucket tips are provided with an access slot along a circumferentially facing edge of the cover at a location where moisture removal grooves of the bucket will intersect with the cover. Machine tooling is then applied to form the grooves along the suction side and adjacent the leading of the bucket. The machining runs out through the access slot forming grooves along the side edge of the bucket cover within the slot. The axial extent of the covers overlying leading and trailing edges of the buckets is maintained while enabling moisture removal by centrifugal action.

Abstract: A grease pump including a gerotor pump. The grease pump includes a head, a source of grease, and a discharge conduit. The head has bores defining an inlet passage and an outlet passage, and additional bores in communication with the inlet passage that lead to an air vent valve and a grease fitting. The gerotor pump is disposed in the head and is caused to rotate by an external, separate rotary power tool. By design, the gerotor pump will stop pumping grease when air accumulates in the outlet passage, and air vent valves in fluid communication with the inlet passage and outlet passage may be used to relieve air from the device.

Abstract: A method and system of evaluating a turbine component comprises obtaining data relating to respective surface conditions at a plurality of different surface locations of the turbine component and calculating the total profile efficiency loss for the turbine component based on the data. Calculating the total profile efficiency of the turbine component may include calculating the local profile efficiency loss percentage for each of the surface conditions at the different surface locations (and/or sub-areas of the different surface locations) and calculating an average of the local profile efficiency loss percentages, each of the local efficiency loss percentages being weighted by respective predetermined weight factors. The turbine component may be a nozzle or a bucket and each of the turbine component's surface locations may be an admission suction surface, an admission pressure surface, a discharge suction surface or a discharge pressure surface.
