The support structure is connected to the base (3), a pair of links (12,13) connecting the cranks (10,11) of shaft (5) to the moveable support (2). One crank (10) is positioned at one outer end (6) of the shaft (5) and the other crank (11) is positioned at the opposite outer end (7) of the shaft (5). Part of the rotating shaft (5) is the rotor (22) of the electric motor (21).

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.

A linear actuator comprises a motor for producing a bi-directional rotational output. A casing is connected to the motor at a proximal end, the casing having an inner cavity defining a joint surface. A shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube is at least partially in the inner cavity of the casing for moving in translation in an axial direction relative to the casing. One or more travelling nut is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the travelling nut being operatively engaged to the shaft for converting a rotational motion of the shaft into a translation of the sliding tube. A liner is between the sliding tube and the joint surface of the inner cavity, an inner surface of the liner defining longitudinal contact surfaces separated by longitudinal grooves, the longitudinal contact surfaces contacting the sliding tube.

The disclosed subject matter relates to an apparatus for simulating motion, comprising: a base; a seat with a seat pan and seat back, the seat having a roll axis and, orthogonal thereto, a pitch axis; a mount mounting the seat to the base at least pivotably about said roll axis and said pitch axis; a left seat back flap and a right seat back flap each of which being pivotably attached to a respective side of the seat back; and a linkage linking said seat back flaps to the base so that, when any one of the sides of the seat back is moved towards the base, the respective seat back flap is pivoted inwards and, when said side of the seat back is moved away from the base, said seat back flap is pivoted outwards.

A method for creating a modified flight simulation program for a flight simulation system includes: obtaining a demonstration flight record associated with a preset track route of a virtual airplane; generating an add-on content pack for the flight simulation program based on the demonstration flight record; and merging the add-on content pack to the flight simulation program to create a modified flight simulation program. The generation of the add-on content pack includes: mapping the preset track route to geographical coordinate data in the real world, creating a first program module associated with a demonstration mode enabling a demonstration virtual flight along the preset track route, creating a second program module associated with an assisted flight mode enabling user control for a virtual flight within a free-flight space, and creating the add-on content pack that includes the first and the second program modules.
