In this study, a moderately flexible rotor is investigated experimentally in water channel. The consists of single blade with simplified rectangular geometry and tested various pitch angles at different rotational speeds. flapwise bending deformation induced torsion the are measured using image processing tools, flow fields extracted Particle Image Velocimetry. behaviour depends strongly on ang...

A variable camber morphing rotor blade with curvilinear fiber composite skin is studied in this paper. The benefits of curvilinear fiber (CVF) composites for morphing skin over the linear fiber are investigated, initially. The skin of a morphing blade is modeled as a plate supported between the D-spar and trailing edge of typical rotor blade dimensions. The CVF composite shows about 60 % increa...

The V-ATPase is a membrane-bound protein complex which pumps protons across the membrane to generate a large proton motive force through the coupling of an ATP-driven 3-stroke rotary motor (V1) to a multistroke proton pump (Vo). This is done with near 100% efficiency, which is achieved in part by flexibility within the central rotor axle and stator connections, allowing the system to flex to mi...

The 10MW high temperature gas-cooled test modular reactor coupled with direct gas-turbine cycle (HTR-10GT) is designed by the Institute of Nuclear Energy Technology (INET) of Tsinghua University in China, in order to experimentally validate the possibility of creating high performance plants with direct closed gas-turbine cycle and the technology for future commercial applications. The vertical...

In order to harness the kinetic energy of marine currents, we propose a novel ocean-current turbine with a horizontal axis. The turbine can be moored to the seabed and function similarly to kites in a water flow. To operate such turbines in a marine current, the resulting rotor torque needs to be canceled. Therefore, the proposed turbine is designed with a float at its top and a counterweight a...

A numerical analysis of deformation the brush seal wire package as part dynamic rotor&stator system gas turbine engines is describes. The estimated definition reaction force based on solving contact problem interaction bristles with each other, rotor and rear plate case, taking into account action distributed flow pressure. Comparison results obtained data well-known experimental studies. A...

Bolted joints are widely used in industrial rotating machines to fasten the adjacent disks together and affect system dynamic properties. Therefore, there is a strong need study their influence on response of such systems. This paper investigated effect eccentric phase difference disk bolted-disk joint rotor dynamics, which takes into account time-varying bending stiffness bolted joint. The mod...

Abstract Aiming at the critical flutter problem of wind turbine blades, which is between classical and stall flutter, a suppression scheme based on radial basis function (RBF) neural network friction compensation backstepping presented. The structure model typical 2D section bending twist spring-mass-damper, rotor variable exciter second-order with disturbance incorporated to control blade. A m...
