智能螺旋桨发展现状及其在临近空间飞行器中的应用

提高推进系统的效率对实现浮空器在临近空间长期悬停意义重大,对国外最新的有关螺旋桨（含旋翼）基于自适应结构变形的重大研究计划和原理进行了深入地分析,旨在找出能突破目前临近空间螺旋桨因设计变量少而导致其效率和工况适应性难于大幅度提高的困境的方法.研究表明,这一困境有望通过自适应结构变形的方式得以解决.

Survey on Smart Propeller and Its Applications in Near-space Propeller Vehicle

For the limit of the amount of design variables , It is difficulty to greatly improve the aerodynamic efficiency and the flight height and velocity adaptability of near-space propeller system, So the paper survey and analyze the foreign major research programs and principles on morphing propeller and rotor structures, trying to find a novel and breakthrough approach to increase significantly the efficiency and flight height and velocity adaptability of near-space propeller system. The study shows that the morphing structures have great potentialities.
