20080223636 | Method and device for self-contained inertial - A novel method and device for self-contained inertial vehicular propulsion using the combined effort of linear and rotational inertial reluctance contained in flywheels. The flywheels are having parallel axial orientation, opposite rotation and opposite alternate cyclic linear reciprocal motion in the direction of vehicular travel. The cyclic reciprocal linear motion of the flywheels have equal peak velocities with differential magnitude of linear accelerations. The differential magnitude of the linear accelerations of the flywheels is the source of linear kinetic propulsion energy. The linear inertial reluctance of the flywheels is used as the propulsion motivating impact momentum by separation and the rotational inertial reluctance of the flywheels is used as dynamic propulsion backrest. Kinetic energy is supplied to each flywheel with integral motor-generators contained within the flywheels and an attached rotational-to-reciprocating transmission is directing kinetic energy into the device in the direction of vehicular travel. The alternating induction and depletion of motivation kinetic energy into the flywheels is reaction-less and causes the differential magnitude of accelerations due to the concurrent and progressive depletion to zero distribution of the induced kinetic energy using a negative feedback loop. The negative feedback loop is accomplished with the formulation of the rotational-to-reciprocating transmission. | 09-18-2008 |
