摘要： An open mold for producing components made of a moldable material such as layered composite materials is made from an additive manufacturing technology. The mold includes at least two compatible mold segments which precisely interlock with and abut against each other. The mold thereby made may be larger than the limited printing area of an additive manufacturing machine.

摘要： Systems and methods include providing a virtual reality (“VR”) flight emulator system that simulates control, operation, and response of a vehicle. The flight emulator includes a control interface and a head-mounted display worn by a user. Motion, orientation, and/or forces experienced by the simulated vehicle are imparted to a user through a motion-control seat. Multiple flight emulators can be connected to a communication network, and a master flight emulator may teleport into a slave flight emulator in order to observe, overtake, override, and/or assume control of the slave flight emulator. Inputs made via the control interface of the master flight emulator or during playback of a pre-recorded training exercise or flight mission are translated into the control interface, head-mounted display, and motion-control seat of the slave flight emulator to provide real-time feedback to the user of the slave flight emulator.

摘要： A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.

摘要： A sensor for monitoring rotors includes a rotating shaft coupled to a set of rotor blades and a non-rotating tube at least partially disposed within the rotating shaft and coupled to the rotating shaft. The non-rotating tube includes a first end and a second end, a sensor mount disposed within the non-rotating tube proximate to the second end of the non-rotating tube. One or more sensors are attached to the sensor mount, wherein the one or more sensors detect one or more parameters associated with the rotating shaft or the set of rotor blades.

摘要： A system and method for preventing a maximum asymmetric condition between pylon tilt angles due to a degraded pylon in a fly-by-wire tiltrotor aircraft during transitions between airplane mode and helicopter mode includes a conversion system for imparting movement on a right and left pylon. A flight control computer is operatively connected to a set of transducers for measuring pylon angles. The flight control computer is further connected to a set of actuators which are attached to each pylon. The flight control computer receives flight dynamics input from the set of transducers and/or the pilot and sends pylon command to the set of actuators. The conversion system measures the difference between the pylon angles during the transition and provides a pylon command adjustment if the difference exceeds a preset threshold.

摘要： A driveshaft includes a first end, a second end, and a length extending from the first end to the second end. The driveshaft includes an engagement section at the first end configured to cooperatively engage and transfer torque to a gearbox. The driveshaft also includes a compressible section configured to selectively decrease the length of the driveshaft. The driveshaft being configured to transition between an engaged configuration, wherein the engagement portion is engaged with the gearbox, and a disengaged configuration, wherein the compressible section is compressed, and the engagement portion is disengaged from the apparatus.

摘要： A duct for a ducted-rotor aircraft may include an internal structure and an aerodynamic exterior skin that is adhesively bonded to the internal structure. The skin may include a leading-edge portion disposed at an inlet of the duct and an inner portion disposed along an interior of the duct. The inner portion of the skin may be bonded to the internal structure with a first bondline of adhesive and the leading-edge portion of the skin may be bonded to the inner portion of the skin with a second bondline of adhesive. One or both of the first and second bondlines of adhesive may be of non-uniform thickness to take up tolerance stackups between the inner portion of the skin, the leading-edge portion of the skin, and the internal structure.

摘要： A hub assembly for a ducted-rotor aircraft includes a plurality of stator supports, a first integral fitting that attaches to first ends of the stator supports, and a second integral fitting that attaches to second ends of the stator supports. The first fitting includes a plurality of motor attachment portions configured to locate and support a motor of the ducted-rotor aircraft, a plurality of fairing mounts configured to support attachment of an aerodynamic fairing to the hub assembly, and a plurality of stator locators configured to locate respective ones of the plurality of stator supports for attachment to the hub assembly. The first fitting has a body portion with an annular wall that supports the motor attachment portions, the fairing mounts, and the stator locators. The first fitting may be fabricated as a monolith that includes the body portion, motor attachment portions, fairing mounts, and stator locators.
