Laser supported propulsion of a micro-airplane with water-covered ablator is demonstrated. The repetitive use of an overlay structure is experimentally demonstrated with a specially-designed water supply. The various transparent overlays are investigated by the CIP-based hydrodynamic code and experiments using a pendulum and semiconductor load cell. The momentum coupling efficiency of 5000 N-sec/MJ has been achieved by ORION experiments that agree with the simulation code. With the maximum efficiency approximately 105 N.sec/MJ predicted by the simulation, 30 pulses of MJ laser can give sound speed to a 10 tons airplane. The concept can also be used for driving a micro-ship inside the human body and a robot under the accidental circumstance of a nuclear power reactor in which large amounts of neutron sources makes electronic devices useless.
