Sikorsky Aircraft | Date: 2017-03-15

A rotor hub fairing system (36) for use in a counter-rotating, coaxial rotor system (12) is provided including an upper hub fairing (38) defined about an axis and a lower hub fairing (40) defined about the axis. A shaft fairing (42) is disposed between the upper hub fairing (38) and the lower hub fairing (40). The geometry of the shaft fairing (42) is configured to encourage a wake adjacent the upper hub fairing (38) to form collectively with a wake adjacent the lower hub fairing (40).

A system for digitizing components of a vehicle includes a 3-dimensional sensing system operatively arranged to monitor a human-machine interface component of the vehicle, and a controller arranged to receive sensed data from the 3-dimensional sensing system. The controller processes the sensed data and outputs a signal indicative of a condition of the human-machine interface component.

A tail sitter aircraft (10) is capable of forward flight and hover operations. The tail sitter aircraft (10) includes a wing (12, 13) and first (14) and second (15) prop-nacelles supportively disposed on the wing. Each of the first and second prop-nacelles includes an articulable rotor (20), which is rotatable about variable rotational axes and which includes blades (22) that are collectively and cyclically controllable in both forward flight and hover regimes.


An active sensing system includes an agent and at least one sensor operatively associated with the agent. The at least one sensor includes one or more emitters configured and disposed to establish a sensing zone. A conflict identification module is configured and disposed to identify one or more sensor conflict regions, and an active sensor controller is operatively connected to the at least one sensor and the conflict identification module. The active sensor controller is configured and disposed to form an adjustment zone within the sensing zone to accommodate the one or more sensor conflict regions.

A gearbox assembly includes a housing with a housing interior. A sump is disposed within a lower region of the gearbox housing. A lubricated transmission element is arranged in the housing interior above the sump. A lubricant impoundment is arranged within the housing and in series between the transmission element and the sump such that lubricant flowing in a primary lubricant flow path between the transmission element and the sump is impounded in the lubricant impoundment, thereby providing a supply of lubricant for a secondary lubricant flow path disposed within the gearbox housing.

One aspect is a flight control system for independent speed and attitude control (70) of a rotary wing aircraft (10) that includes a main rotor system (12) and a translational thrust system (30). The flight control system includes a flight control computer (75) configured to interface with the main rotor system (12) and the translational thrust system (30). The flight control computer includes processing circuitry configured to execute control logic. A pitch attitude reference generator (102) provides a pitch attitude reference (110) to a main rotor controller (12) to command the main rotor system based on pilot input (112). A longitudinal reference generator (104) produces a longitudinal reference (122) as a longitudinal position or longitudinal velocity based on pilot input. An attitude-to-propulsor crossfeed (106) converts the pitch attitude reference (112) into a propulsor trim adjustment (120). A propeller pitch controller (114) combines the longitudinal reference (122) and the propulsor trim adjustment (120) into a propeller command (134), and provides the propeller command to the translational thrust system (30).


Disclosed is an apparatus for in-situ filtering and monitoring of a lubricating fluid which includes, among other elements, a housing, a filter assembly and a lubrication monitoring module. The housing is adapted for being secured directly to a source of lubricating fluid and defines an internal filter chamber. The filter assembly is positioned at least partially within the internal filter chamber of the housing and the lubrication monitoring module is in fluid communication with the internal filter chamber of the housing. The filter assembly and the lubrication monitoring module are arranged so as to create first and second flow paths for lubricating fluid within the housing. The first flow path directs a portion of the lubricating fluid from the source, through the filter assembly where it is conditioned and returned to the source. The second flow path directs a second portion of the lubricating fluid from the source to the lubrication monitoring module and subsequently it is returned to the source.

A system for transferring a hole pattern from a first component to a second component configured to couple to the first component is provided including a contour plate having a drill plate with a hole pattern substantially identical to the hole pattern of the first component. The position of the drill plate is adjustable to match the hole pattern of the drill plate with the hole pattern of the first component. A slidable fixture configured to support the second component is movable to align the second component with the drill plate such that the hole pattern of the drill plate in relation to the second component matches the hole pattern of the drill plate in relation to the hole pattern of the first component. The hole pattern of the drill plate is used to create a hole pattern in the second component matching the hole pattern of the first component.

A method for imaging a moving object includes scanning a predetermined area with at least one distance sensor to form an image of a structure of a moving object using a safe sensing time window to periodically refresh the image. The images of the structure are compared a known model of the structure to estimate rates of motion. A refined time window is determined based on the estimated rates of motion to monitor the moving object with increased accuracy and/or range compared to the safe time window.
