Coupling Analysis of Turbocharger Compressor Blade Vibration and Blade Profile Optimization
2021 IEEE International Conference on Electrical Engineering and Mechatronics Technology (ICEEMT), 2021The optimization of the turbocharger structure can significantly improve its properties. In order to establish the dynamic coupling formula, the blade was simplified as a thin flexible rectangular plate moving in space, and the Lagrange dynamic equation was used to solve the problem.

Laser profiling of 3D microturbine blades
SPIE Proceedings, 2003We have used KrF excimer laser ablation in the fabrication of a novel MEMS power conversion device based on an axial-flow turbine with an integral axial-flux electromagnetic generator. The device has a sandwich structure, comprising a pair of silicon stators either side of an SU8 polymer rotor.

A Robust Blade Profile Feature Parameter Identifying Method
2021The blade is the key part of aero-engine. The detection of the blade profile feature parameters is an important aspect in blade manufacturing. However, the surface of the blade is free-form surface. It is difficult to extract feature parameters. In this paper, a robust feature identify method is proposed.

Low-profile Ultra-Wideband Blade Monopole Antenna
2018 9th International Symposium on Telecommunications (IST), 2018A low-profile ultra-wideband blade monopole antenna, which enclosed in a radome, at 400-3000 MHz bands is presented. The antenna configuration is a blade with slanted edge which demonstrates the enhanced impedance bandwidth compared with a blade antenna with equal total height but no slanted edge. The simulated and tested Voltage Standing Wave Ratio of

Optimization of Stacking Line and Blade Profile for Design of Axial Flow Fan Blade
Volume 2: Fora, 2008This work presents a numerical optimization procedure for a low-speed axial flow fan blade with weighted average surrogate model. Reynolds-averaged Navier-Stokes equations with SST turbulence model are discretized by finite volume approximations and solved on hexahedral grids for flow analyses.
