Abstract: An impulse launcher is provided with a motor to store rotational kinetic energy in a flywheel. The stored kinetic energy is released using a planetary gear transmission that links the flywheel to a drive shaft. The kinetic energy is released when the planetary gear carrier is decelerated using a brake.
