摘　　要：随着激光推进技术的提出和高能激光技术的发展,以激光作为推进能量的飞行器将会有效解决降低火箭成本和提高火箭有效载荷的问题.设计了一种新型激光推进飞行器--光船;建立了合理的物理模型和流体力学模型;用数值方法研究其喷管形状、位置对冲量耦合系数及推力的作用规律;根据数值计算结果对光船结构进行改进,确定了比较合理的光船结构.With the suggestion of the laser propulsive technology and the development of the high energy laser technology, laser propelled vehicle will solve difficult problems, such as how to decrease the cost of rocket and how to raise zhe padload. A new type craft propelled by laser, lightcraft, is put forward in this paper.The reasonable physical model and fluid mechanics model, and preliminary studies are given to seek for the change law of thrust affected by the lightcraft's structure. Based on the calculation of numerical technique, a reasonable lightcraft's structure is designed. Because of it's low cost and high payloads, this new craft will be widely used in spaceflight field and push on the development of spaceflight technology.
