Abstract

Some implementations include a method for operating a centrifuge-based-flight simulator in at least one of several different modes: a heightened G-force mode, a normal G-force mode; and transition modes (i.e., ramp-up or ramp-down modes) between the heightened G-force and normal G-force modes. During the normal-G-force mode the simulator ceases planetary motion altogether or substantially decreases rotations to replicate a plurality of flight conditions that physically imparts, on the trainee during operation of the simulator, a G-force that is not greater than approximately one (1) G. The reduction of planetary motion while maintaining realistic motion and force sensations that are appropriate for the virtual-flight conditions being experienced allows realistic flight simulation experience for the trainee and reduces the negative effects of constant planetary motion.

Claims (22)

1. A method for controlling a centrifuge-based-flight simulator, comprising:

generating a virtual scene in a cockpit unit of a virtual plane representing an actual-predetermined aircraft replicated by the simulator, wherein the cockpit unit is located at a distal end of an arm of the simulator;

rotating the simulator at a plurality of rates of rotation that physically imparts, on a trainee while operating the virtual plane during operation of the simulator, a G-force that is greater than about one (1) G, to replicate a plurality of first-flight conditions which causes the trainee to experience heightened G-forces within the simulator, wherein the G-forces substantially match actual G-forces, which would occur in the predetermined aircraft during the same flight conditions as the simulated first-flight conditions, and wherein the first-flight conditions includes at least one of: taking off, landing, banking, encountering severe weather, and encountering wake turbulence in the virtual plane;

ceasing the rotation of the simulator thereby physically imparting on the trainee during operation of the simulator, a G-force of about one (1) G, to simulate a plurality of second-flight conditions which cause the trainee, while operating the virtual plane within the simulator, to experience no heightened G-forces, wherein the about one (1) G force substantially matches the actual G-force which would occur in the predetermined aircraft during the same flight conditions as the simulated first-flight conditions, and wherein the second-flight conditions includes at least one of: straight-level flight, wide turns, non-turning ascents, and non-turning descents;

decelerating the rotation of the flight simulator at a rate below a generally perceptible threshold for human detection by the trainee while operating a virtual plane within the simulator to transition to from one or more of the plurality of first-flight conditions to one or more of the plurality of second-flight conditions;

accelerating rotation of the flight simulator at a rate below a generally perceptible threshold for human detection to transition to from one or more of the plurality of second-flight conditions to one or more of the plurality of first-flight conditions;

monitoring a position of the virtual plane relative to a predetermined virtual boundary; and

performing at least one of accelerating rotation of the arm of the simulator, decelerating rotation of the arm of the simulator, and maintaining the arm of the simulator in a stationary position, based at least in part, on the position of the virtual plane relative to the virtual boundary, and whether the virtual plane is experiencing the first or second-flight conditions.

2. A system for operating a centrifuge-based-flight simulator, comprising:

one or more processors, and computer-readable media communicatively coupled to the one or more processors collectively forming a controller, the controller operable in one of:

a heightened G-force mode in which the controller instructs the simulator to replicate a plurality of first-flight conditions by rotating the simulator at a plurality of rates of rotation that physically imparts, on a trainee during operation of the simulator, a G-force that is greater than about one (1) G;

a normal G-force mode in which the controller instructs the simulator to replicate a plurality of second-flight conditions by ceasing the rotation of the simulator thereby physically imparting on the trainee during operation of the simulator, a G-force of about one (1) G;

wherein the controller is further operable in a ramp-down mode in which the controller instructs the simulator to transition from one or more of the plurality of first-flight conditions to one or more of the plurality of second-flight conditions by decelerating the rotation of the flight simulator at a rate below a generally perceptible threshold for human detection by the trainee while operating a virtual plane within the simulator,

wherein the G-forces substantially match actual G-forces, which would occur in a predetermined aircraft during the same flight conditions during the simulated first-flight conditions and simulated second-flight conditions,

wherein the first-flight conditions includes at least one of: taking off, landing, banking, encountering severe weather, and encountering wake turbulence in the virtual plane,

wherein the second-flight conditions includes at least one of: straight-level flight, wide turns, non-turning ascents, and non-turning descents;

wherein the controller is further operable to:

generate a virtual scene in a cockpit of a virtual plane representing an actual-predetermined aircraft replicated by the simulator;

monitor a position of the virtual plane relative to a predetermined virtual boundary;

transition between the heightened and normal G-force modes based at least in part, on the position of the virtual plane relative to the virtual boundary; and

wherein the controller is further operable to maintain the arm of the simulator in a stationary position based during the second-flight conditions.

3. The system of claim 2 , wherein the controller is further operable to instruct the simulator to move to replicate movement of a physical plane when performing at least one of a pitch, roll, and yaw.
