A vehicle nonlinear dynamics simulation device, such as flight simulator, including a motorized spherical vehicle suspended inside another spherical shell which has smooth inner surface. The spherical vehicle is supported by a plurality of spiky legs of either air-bearing assemblies or omni-directional ball bearing assemblies. The outer spherical shell is supported by three controllable translational motion platforms. Simulating equipment for a pilot cabin is mounted inside the spherical vehicle. The spherical vehicle has driving, restoring, and damping capabilities in roll, pitch, and yaw directions and is capable to rotate 360 in any directions. Therefore it provides a dynamically equivalent model to simulate a vehicle rotational dynamics. The driving and restoring means include Omni wheel assemblies mounted outside of the spherical vehicle and operable to contact the inner surface of the shell to drive the spherical vehicle in roll, pitch, and yaw directions. The driving means include electrical motors. The restoring and damping mechanisms are provided by rotational springs and rotational dampers, respectively. The rotational movements of the spherical vehicle are active and controlled by the driving system and also by the nonlinear dynamics of the spherical vehicle itself, in contrast to the passive movements of the simulation platforms currently used in industries.

A method of operating a targeting system simulation tool (TSST) includes providing a TSST configured to receive an obstacle/effect parameterization, a simulation parameterization, a sensor parameterization, an aircraft parameterization, and an autonomy parameterization. The method further includes receiving by the TSST, at least one of each of an obstacle/effect parameterization and a simulation parameterization. The method further includes receiving by the TSST, either (1) a sensor parameterization or (2) an aircraft parameterization. The method further includes operating the TSST to apply the provided ones of the obstacle/effect parameterization, simulation parameterization, sensor parameterization, and aircraft parameterization to generate a value, value range, or value limit for the unprovided aircraft parameterization or unprovided sensor parameterization.

An input device for providing user input to a computing device includes a seat portion allowing a user to sit on the device. The input device further includes several human interface devices having positional sensors that detect changes in rotation or translation of a movable tactile surface with respect to a fixed tactile surface and provide a signal indicative thereof.

A training system includes a tether configured to removably attach a training device to an overwater aircraft which is configured to at least take off and land over water. The training system also includes the training device which has a negative buoyancy and has an out-of-water weight which prevents sustained flight by the overwater aircraft when the training device is at least partially out of the water.

Aspects of disclosure provide a system for reducing traction of a vehicle. The system includes a mobile controller, and a remote controller. The mobile controller is configured to control release of a liquid. The mobile controller corresponds to a vehicle and configured to direct the release of the liquid to specified wheels of the vehicle. The remote controller is in wireless communication with the mobile controller. The remote controller is configured to store a liquid release setting for the mobile controller, to receive a selection of the vehicle, and to issue a liquid release command including the liquid release setting to the mobile controller corresponding to the selected vehicle. The mobile controller corresponding to the selected vehicle is configured to initiate a release of the liquid directed to one or more wheels of the selected vehicle to reduce traction of the selected vehicle according to the liquid release setting.
