Abstract: An ice protection system is configured for a rotor blade having a leading edge along at least a portion of a spanwise length extending between a root portion and a tip portion. The system has an electric spanwise anti-ice heater configured for placement on the leading edge of the blade and a first electric spanwise de-ice heater adjacent the anti-ice heater and having varying chordwise dimensions. The de-ice heater is configured for placement on an upper surface of the blade or a lower surface of the blade. Electrical connectors for each heater are configured for connection near the root portion of the blade to a source of electrical power.

Abstract: 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.

Abstract: Systems and methods include providing a virtual reality (“VR”) flight teleport system that include a master aircraft and a plurality of remote slave aircraft connected through a network. A flight emulator in the master aircraft allows a user in the master aircraft to “teleport” into a remote slave vehicle in order to observe and/or assume control of the remote slave aircraft. Motion of, orientation of, and/or forces acting on the remote stave vehicle are emulated to the user of the master vehicle through a pilot control interface, a motion-control seat, and a head-mounted display to provide real-time feedback to the user of the master aircraft. Inputs made via the pilot control interface of the flight emulator system in the master aircraft are transferred through the network into the flight control system of the remote slave vehicle to control operation of the remote slave vehicle.

Abstract: In some embodiments, a rotorcraft includes an engine, a rotor hub assembly mechanically coupled to the engine and a plurality of rotor blade assemblies rotatably mounted to the rotor hub assembly. Each of the rotor blade assemblies includes a rotor blade having a leading edge and an erosion shield system extending spanwise along the leading edge of the rotor blade. The erosion shield system includes a plurality of erosion shield segments positioned adjacent to one another forming joints therebetween wherein, the joints deform responsive to strain experienced by the rotor blade, thereby isolating the erosion shield segments from at least a portion of the strain experienced by the rotor blade.

Abstract: An erosion protection system (EPS) has a first erosion protection unit (EPU) having a first ligament and a first scale attached to the first ligament, the first scale having an outer hardness that is greater than a hardness of the first ligament. The EPS also has a second EPU having a second ligament and a second scale attached to the second ligament, the second scale having an outer hardness that is greater than a hardness of the second ligament. The EPS also has an interstitial space between the first ligament and the second ligament wherein at least one of (1) the first scale overlaps at least a portion of the second EPU and (2) the second scale overlaps at least a portion of the first EPU.

Abstract: Systems and methods include providing a virtual reality (“VR”) flight emulator 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. The user of the flight emulator can virtually teleport into a slave virtual or remote aircraft in order to assume control of the slave virtual or remote aircraft. Motion of, orientation of, and/or forces acting on the slave virtual or remote aircraft are imparted to a user through a plurality of galvanic vestibular stimulation (GVS) devices when the user of the flight emulator is virtually teleported into the slave virtual or remote aircraft. The flight emulator can be connected through a communication network to a plurality of other flight emulators. The flight emulator can also be installed in an aircraft and connected through the communication network to a plurality of other remote aircraft.
