项目摘要

Centimeter sized airplane without engine and controlling device can be flown by laser from ground. Power can be supplied by laser ablation based laser irradiation. Many paper-airplanes are thrown to the sky driven by lasers, and the location and absorption rate of carbon dioxide in the air can be measured simultaneously with another laser, where the three dimensional measuring method of carbon dioxide distribution would be established. It can offer supervisory method of the greenhouse gas emission reduction that executes into action from 2008 by the Kyoto protocol.We have already succeeded in one shot laser driving of paper-airplane by 0.5W laser power, first time in the world and also in continuous pulses.This system can make the generated driving force over thousand times larger than former system. This idea was proposed by Yabe in 1976,and recently it receives worldwide attention because using only water must be friendly to environment.1.Three dimensional simulationSince our former technique that uses metal target is in danger of affecting environment by exerting of metal gas, we developed new Water Film Cannon(WFC) target that uses only the water membrane. Furthermore, the plasma generation process based on the laser absorption was added to the three dimensional simulation code that uses the CIP method and then we succeeded in optimizing a design of target structure.2.Examination of pursuit methodExamination of lens and sensor systems was carried out in order to pursue and control the movement of airplane.3.High propulsion efficiency of micro airplaneAiming toward small-sized and high propulsion efficiency of micro airplane, the basic experiments of the WFC target were conducted. Experimental results were reproduced by the numerical simulations to analyze the phenomenon, and the water film thickness can be optimized to get high efficiency of propulsion.

没有发动机和控制装置的厘米大小的飞机可以从地面用激光飞行。功率可由基于激光烧蚀的激光照射来提供。许多纸飞机是在激光的驱动下被抛向天空的，可以与另一台激光同时测量空气中二氧化碳的位置和吸收速率，从而建立起二氧化碳分布的三维测量方法。该系统可为《京都议定书》于2008年开始实施的温室气体减排提供监测手段。我们已成功地用0.5W激光功率对纸机进行了一次激光驱动，这在世界上尚属首次，而且还是连续脉冲。该系统可以使产生的驱动力比原来的系统大1000倍以上。这个想法是由Yabe在1976年提出的，由于只用水必须对环境友好，所以最近受到了全世界的关注。1.三维模拟鉴于我们以前使用金属靶材的技术存在使用金属气体对环境造成影响的危险，我们研制了只使用水膜的新型水膜炮靶材。在此基础上，将基于激光吸收的等离子体产生过程加入到基于CIP方法的三维仿真程序中，成功地进行了目标结构的优化设计。2.跟踪方法的验证为了跟踪和控制飞机的运动，进行了透镜和传感器系统的检查。3.微型飞机的高推进效率针对微型飞机的小型化和高推进效率，进行了WFC目标的基础实验。通过数值模拟再现了实验结果，并对水膜厚度进行了优化，以获得较高的推进效率。
