Regardless of the orientation of the six masses, each pair of the six interconnected rotating masses may share substantially the same center of gravity and generate a separate yet interactive kinetic energy and angular momentum in each of the three planes, thereby providing resistance to rotational forces from external sources.

Abstract: The present technical solution solves a problem of keeping a given direction by use of an element stabilized in a given plane of inertial space, irrespective of disturbing torques, precessions of gyroscopes, and turns of a movable object in the given plane of inertial space when the current technical solution is used on the movable object. This solution is based on forcing precessions of two one-axis gyrostabilizers in opposite directions. The gyrostabilizers are connected with each other by a connection unit comprising a stabilized element. Since in the present solution low precision gyroscopes can be used, then the proposed solution can be implemented in a small-size version.

Abstract: Disclosed herein are two separate processes that do not require a propellant and do not produce an equal and opposite reaction against any external form of matter in the Local Inertial Reference Frame and do not violate Newton's Laws in the Universal Reference Frame. The first process produces horizontal motion, relies on the earth's gravitational field as an external force, and has been successfully tested. The second process produces vertical motion and relies only on the aether. It has been successfully tested considering the effect of the earth's gravity. Due to the law of conservation of angular momentum, the first process is considered by some to not be possible, but with the proper use of an external field (for example, gravity) and the phenomenon of precession, it is clearly possible. A clear distinction is made between a simple rotor and a gyroscope which is a far more complex device.

Abstract: A multi-axis gimbal has each axis defined by a respective spherical shell driven by a flat, compact motor attached to the driven shell and to a next outer shell (or to an external mounting platform, in the case of the outermost shell). The shells rotate about respective axes. In one configuration, the outermost shell is referred to as the “azimuth” shell because in use it rotates about a vertical axis. The next inner shell is an elevation shell that rotates about a first horizontal axis that is orthogonal to the axis of the camera or other sensor payload. An optional third shell can be used to provide “roll” motion, such as rotating a camera about its axis to obtain a particular rotational orientation with respect to a target.

The system includes a vehicle, such as a spacecraft, a rotational assembly mounted on the vehicle and rotatable about an axis of rotation relative to the vehicle, and one or more momentum devices mounted on the rotational assembly and generating a momentum vector component perpendicular to the axis of rotation.

Abstract: A reaction wheel system is provided that includes at least two rotors. The first rotor is the primary rotor that provides the large output torques to the vehicle. The second rotor is a vernier control rotor. The primary rotor and vernier control rotor each rotate about a common axis. The vernier control rotor has an inertial mass that is less than the inertial mass of the primary rotor, and rotates independently of the primary rotor. Because the vernier control rotor can be rotated independently from the primary rotor, it can be used to significantly improve the performance of the reaction wheel system. Specifically, the vernier control rotor is used to provide relatively small output torques. These relatively small output torques can be used to reduce the disturbances created by motor ripple, provide precise torque output control and/or reduce the disturbances created by static friction.

Abstract: A gyrostabilizer without a physical shaft or axle is constructed. The stabilizer has dual counter-revolving concentric rings filled with weights such as spherical balls that are propelled in orbital fashion by fluid pressure or electromagnet propulsion. The diameter of the concentric ring can vary from a few inches to more than ten (10) feet. Without an axle or shaft the weight of the gyrostabilizer is shifted to the perimeter where most of the momentum is generated at a fraction of the weight of gyrostabilizers that spin on an axle. Also without an axle or shaft the space between the center of revolution and the revolving balls is usable or void. When properly mounted in a vehicle or structure unsteadiness such as tremors, vibrations, sway, pitch, roll, yaw can be dampened.

Abstract: According to the preferred embodiments of the present invention, an apparatus and method for creating directional movement using the natural forces of rotational energy in a gravitational field is disclosed. The present invention is a combination of three interconnected gyroscopic ring-like rotating masses, with each of the three ring-like masses rotating in a separate plane.

At high enough levels of angular momentum, outside cosmic forces, including the gravitational force of the environment, will cause the interconnected rotating masses to seek equilibrium by moving away from the strength of the gravitational force.
