ABSTRACT:
A non-linear propulsion and energy conversion system, in one embodiment, includes an impulse drive having a frame with inner and outer pairs of driving members movable relative to the frame. Guides in the form of rails are provided for supporting the driving members so that they move along a path confined by the rails when kinetic energy is provided thereto. Solenoid switches are located at each end of the frame and are operable to cause the outer driving members to move linearly along the rails in opposite directions towards each other. At least one of the inner members has a pair of rotatable discs mounted thereon which rotate upon interaction with one of the outer members. The other inner member interacts with the other outer member in a manner so that it transmutes a greater portion of the translational kinetic energy and linear momentum applied thereto by the outer member into linear motion. Thus, the other inner member moves linearly along the path at a greater linear velocity, translational kinetic energy and linear momentum than the one inner member. Brakes are provided in the frame for decelerating and stopping both of the inner members relative to the frame. This process yields a resultant net impulse to the center of mass of the combined system in the direction of movement of the inner member with the greater linear momentum. The resultant net impulse accelerates the combined center of mass of the frame from a state of complete rest to a state of resultant, continuing, uniform motion. A plurality of the above-mentioned drives can be secured to the chassis of a vehicle to allow the vehicle to be accelerated or decelerated as desired. In another embodiment, the system can be used to absorb energy and momentum by converting a portion of the relative linear momentum of an object into angular momentum of at least one disc mounted on an object which is either stationary and integral to a structure, or able to move and then be decelerated and stopped by brakes in the framework of the structure.
