TL;DR: In this paper, the airfoil of nano rotor was optimized based on the controlled elitist Non-dominated Sorting Genetic Algorithm II (NSGA-II) coupling with the parameterization method of Class function/Shape function Transformation technique (CST) and the multi-objectives function processing method of statistical definition of stability.

TL;DR: In this paper, a multi-heating point coordinate temperature control method for realizing a high-accurate uniform temperature field of a gyroscope was proposed. But the method is characterized in that a PWM (Pulse-Width Modulation) signal drives an MOS (Metal Oxide Semiconductor) power transistor to output control quantity to heating plates in a corresponding control device according to the following steps of heating each heating point with the maximum power until the temperature of any one heating point of a controlled device is heat to be 85 percent of the target temperature sTarget

TL;DR: In this paper, five test benches with highly sensitive mechanisms were successively designed in order to measure the thrust and torque of nano-rotors simultaneously and respond to the change of variables rapidly with sufficient accuracy.

TL;DR: In this article, a five-cooperative low Reynolds number aerodynamic model was proposed for the development of small unmanned aerial vehicles (UAVs) and the urge for building the experimental facilities has emerged for the research on the low Reynolds numbers aerodynamics.

TL;DR: In this paper, an aerodynamic design optimization of a hypersonic rocket sled deflector using the free-form deformation (FFD) technique is presented, where the objective is to optimize the aerodynamic shape of the hype...
