Roy Thornson based system.

Roy Thornson has invented inertial propulsion with two weights rotating on inner static gears. Those weights were mounted on the same gear in dimension and the gear with the weights were rotating on the circumference of the static gears, which were inside. In some analyses there was indicated that Thornson drive is working correctly and there were experiments with this dive based on mounting a propulsion unit on a bout in swimming pool. Analyses and experiments have clearly indicated that propulsions are effective. I've decided to visualise the principle of working of this propulsion and I have made some animations on 3D software. This simple principle of operation is based on applying synchronization of rotating gears in this way that the weight attached to one gear is hidden on bottom side and is extending on the outside on top part of the device. Such a behavior of mechanism is based on proper application of gears and creating the proper distance between main shaft and dimension of the caring rotor; thus, the weight can pass inside two free spaces in this rotor rotating on its own axis of rotation. The weight is mounted on roller or ball bearings also the main shaft is mounted on the bearings. Additionally in the static gear there is a hole making available of passing the thin part of the main shaft inside. The static gear is attached to external rim so it can't rotate. The paired system is also shown at the bottom for making balance of the system. However, system can generate a lot of vibration due to not balanced centrifugal force at the bottom of the device. The side centrifugal forces will be cancelled by self-balancing of the system due to system can be paired.
