Real-time solution of nonlinear potential flow equations for lifting rotors

Chinese Journal of Aeronautics 2017年第3期30卷 871-880页

作者： Jianzhe HUANG david peters Department of Energy and Power Engineering Harbin Engineering University Department of Mechanical Engineering and Materials Science Washington University in St.Louis

Analysis of rotorcraft dynamics requires solution of the rotor induced flow ***,the appropriate model to be used for induced flow is nonlinear potential flow theory（which is the basis of vortex-lattice methods）.These nonlinear potential flow equations sometimes must be solved in real time––such as for real-time flight simulation,when observers are needed for controllers,or in preliminary design *** this paper,the major effects of nonlinearities on induced flow are studied for lifting rotors in low-speed flight and *** approach is to use a nonlinear statespace model of the induced flow based on a Galerkin treatment of the potential flow equations.

Optimum blade loading for a powered rotor in descent

引用

Chinese Journal of Aeronautics 2016年第3期29卷 580-584页

作者： Ramin Modarres david A.peters Department of Mechanical Engineering & Materials Science Washington University in St.Louis

The optimum loading for rotors has previously been found for hover, climb and wind turbine conditions; but, up to now, no one has determined the optimum rotor loading in descent. This could be an important design consideration for rotary-wing parachutes and low-speed des- cents. In this paper, the optimal loading for a powered rotor in descent is found from momentum theory based on a variational principle. This loading is compared with the optimal loading for a rotor in hover or climb and with the Betz rotor loading （which is optimum for a lightly-loaded rotor）. Wake contraction for each of the various loadings is also presented.

众所周知,非传染性疾病(NCDs)是人类健康和发展所面临的最大挑战之一,全球出台了很多有关防控的政治承诺、这其中最知名的当属《联合国可持续发展目标》(SDGs),明确提出了“到2030年将NCDs导致的过早死亡减少三分之一”的奋斗目标2。但从当前的全球降低速率来看,理想和现实之间还有很大差距3。而更令人揪心的“国际共识”是,世界卫生组织(WHO)推广的“最划算措施”等循证干预并未落实到位,有相当大比例的NCDs导致的过早死亡案例原本可以避免3-5。

底特律的未来街道将会为行驶于其上的车辆充电未来的电动车充电。有可能藏在底特律一条街道的沥青之下。这是美国首度将电动车充电技术内嵌于公共道路中。这条电动车充电道路建于底特律市中心外一段四分之一英里(约402.34米)长的街道中,是对一项被称为磁共振感应的新兴技术进行测试。它是利用内嵌于街道里的铜线圈将电力从电网传送给路面上方经过的电动车。车载接收器会吸收那些电力——通常只有少量而为电池持续充电。
