Abstract: Embodiments are directed to an aircraft fuselage comprises two keel beams and two roof beams. Each keel beam is formed as a single component having no joints. Each keel beam comprises a first portion that is configured to define a floor of an aircraft and a second portion that is configured to define a tail section of an aircraft. The second portion is positioned at an angle relative to the first portion. Each roof beam is coupled to the second portion of a corresponding keel beam at a point remote from the first portion. Each roof beam and a corresponding keel beam are positioned along a single butt line relative to an aircraft fuselage centerline. Frame members are coupled to both keel beams and both roof beams.

Abstract: A rotor assembly has a rotor hub having a unitary structure. The rotor assembly further includes a unitary crosshead having a first upper tab and a first lower tab located vertically below the first upper tab. The first upper tab and the first lower tab define a slot therebetween to accept a first pin of the first rotor blade. A second upper tab and a second lower tab located vertically below the second upper tab define a slot therebetween to accept a second pin of the second rotor blade. A first recess is provided between the first lower tab and the second lower tab so that the crosshead comprises no material directly between at least a portion of the first lower tab and the second lower tab along at least one straight path.

Abstract: Embodiments are directed to systems and methods for utilizing aircraft cockpit and cabin lighting to provide both power and data transmission to occupants. Data and power may be transmitted on non-visible and/or visible spectrums. The visible light may be used independently for aircraft illumination. Data for the cockpit allows for quick upload and download of flight planning and maintenance data to an electronic flight bag. The electronic flight bag may also be able to receive power from cockpit and cabin lighting during flight.

Abstract: A failsafe multimode clutch assembly is positioned in a powertrain of a rotorcraft. The clutch assembly includes a freewheeling unit having input and output races. The freewheeling unit has a driving mode in which torque applied to the input race is transferred to the output race and an overrunning mode in which torque applied to the output race is not transferred to the input race. A bypass assembly has an engaged position that couples the input and output races of the freewheeling unit. An actuator assembly must be energized to shift the bypass assembly from the engaged position to a disengaged position. In the disengaged position, the overrunning mode of the freewheeling unit is enabled such that the clutch assembly is configured for unidirectional torque transfer. In the engaged position, the overrunning mode of the freewheeling unit is disabled such that the clutch assembly is configured for bidirectional torque transfer.

Abstract: A method includes acquiring a current condition indicator of a condition indicator set associated with an operating condition of a vehicle, the condition indicator set indicating sensor readings associated with an operating element of the vehicle under the operating condition, determining, by a data server, a volatility over a window of the condition indicator set based, at least in part, on differences between adjacent data points in the window, wherein the window includes the current condition indicator, determining, by the data server, a movement over the window of the condition indicator set based, at least in part, on a difference between two selected data points in the window, determining a volatility-based movement significance over the window of the condition indicator set based, at least in part, on a ratio of the movement to the volatility, determining, by the data server, whether a trend associated with the operating element is indicated based, at least in part, on the volatility-based movement significance, and generating, by the data server, an alert signal in response to the determining that the trend is indicated.
