This paper presents the design of an aquatic robot actuated by one internal rotor. The body has a cylindrical form with base in symmetric airfoil sharp edge. For this object, equations motion are presented Kirchhoff for rigid ideal fluid, which supplemented viscous resistance terms. A prototype rotor is developed. Using prototype, experimental investigations fluid carried out.

The paper proposes a methodology for reliable design and maintenance of wind turbine rotor blades using a condition monitoring approach and a damage tolerance index coupling the material and structure. By improving the understanding of material properties that control damage propagation it will be possible to combine damage tolerant structural design, monitoring systems, inspection techniques a...

We inlrOduee the description of translational, orientational and internal order parameters in liquid crystals. We give a systcmatic approach 10 the identification of the relevant paramctcrs as cxpansion coefficients of the singlct distribution function in a suitable basis seL The construction of approximate distnOutions from a limited set of order paramcters using the maximum cnuopy principle i...

We consider a BEC of rigid rotor molecules confined to quasi-2d through harmonic trapping. The are subjected an external electric field which polarizes the gas, and interact via dipole-dipole interactions. present description ground state low-energy excitations system including analysis mean-field energy, polarization, stability. Under large fields gas becomes fully polarized we reproduce well ...

This paper introduces the characteristics of unbalanced fault and handling method rigid rotor fault, expounds process large fan through two balancing cases, which can be used for reference to analysis power plant rotating auxiliary equipment.
