最近,美国奥本大学的研究人员用一架装有固态自适应旋翼(SSAR,solid-state adaptivemain rotor)系统的无人驾驶直升机进行了首飞试验.据这些研究人员声称,这种自适应旋翼技术如果发展下去,有可能对减轻全尺寸直升机旋翼系统的重量,降低其阻力、设计复杂性、成本和雷达特征值大有好处.这架小型直升机还有可能作为美国国防研究计划局正在研究中的小型和微型旋翼无人机的技术试验台.该机原为飞机业余爱好者制造的一架遥控直升机,后来改装了奥本大学研制的小型 Recently, researchers at Auburn University in the US conducted the first flight tests with an unmanned helicopter equipped with a solid-state adaptive principal rotor (SSAR) system, and according to the researchers, the adaptive rotor If technology continues, it may be of great benefit to reduce the weight, reduce the drag, design complexity, cost and radar eigenvalues ​​of full-scale helicopter rotor systems, and it is also possible that this small helicopter is being studied as part of the Defense Advanced Research Projects Agency Small and micro rotor UAV technology test bed.The aircraft was originally a helicopter built by amateur enthusiasts, later modified Aobun University developed a small
