In previous papers, we reported the successful flight of paper‐airplane‐about 5 cm‐size [1]. Since then, we try to find out a new possibility of the laser propulsion that uses overlay structure especially using water leading to high efficiency [2]. In order to this concept in high altitude, we need to insulate the water layer from vacuum, otherwise water will be evaporated or freeze in vacuum condition. For this purpose, we here propose an “air curtain”. We have done simulation and experiments on this concept. Furthermore, we examined in detail the various features of water exotic target by pendulum and semi‐conductor load cell. The coupling coefficient and specific impulse are discussed both by simulation and experiments.
