Aerial respiration

Observation of breakdown induced by CO_2 laser with air-breathing mode;

空气呼吸模式CO_2激光等离子体光谱观察

Adopting the numerical method of differential equation to solve the motion equations of micro-aircraft propelled by pulse ground based laser,the flight characteristics of aircraft in air-breathing mode,ablative mode and combining air-breathing mode with ablative mode are discussed.

计算分析发现:空气呼吸模式推进飞行器的最大速度有限;烧蚀模式可以使飞行器产生很高的速度,提高冲量耦合系数和比冲,有利于提高飞行器的最高速度;两种模式相结合的推进方式提高了有效载荷比,但能源利用效率比烧蚀模式要低。
