This paper presents analysis of stress intensity factors at blade mounting locations of steam turbine rotor system. General expressions for the stresses induced in a rotating disc are derived and these equations are applied to steam turbine rotor disc. It... see more

The Articulating of H-Rotor is a development of the turbine from H-Darrieus which has a straight blade tilted with the aim of correcting poor self-starting due to the dominance of lift force. How likely is the influence of straight blade slope on turbine ... see more

Pemusnahan eksergi pada turbin gas terjadi karena adanya gesekan antara fluida kerja dengan sudu – sudu turbin yang menyebabkan terjadinya pembangkitan entropi pada fluida kerja. Untuk sistem turbin gas dengan fluida kerja yang bertekanan dan temperature ... see more

The development of physics based analysis to predict the hover performance of a micro rotor system meant for a hover capable micro air vehicle for studying the role of blade geometric parameters (such as planform, twist etc.) is discussed. The analysis is... see more

The paperis devoted to vertical axis wind turbine combined rotor blade profile optimalselection. It includes the description of wind turbine optimization parameters, the statement ofmulticriteria optimization problem and the description of hybrid optimiza... see more

Computational method to determine the optimal pitch angles of straight blades for Darrieusrotor was produced. It was shown that the controlling of the blades deflection provides to create and increasethe starting torque and also to enlarge the rotor effic... see more

In this paper results of measurements of velocity distribution in the blade passage of radial rotor are presented. Construction of professional test rig with covered rotor passage and thermoanemometr usage made possible fluid flow visualization and detail... see more

The aerodynamic design of rotor blades is challenging, and is crucial for the development of helicopter technology. Previous aerodynamic optimizations that focused only on limited design points find it difficult to balance flight performance across the en... see more

Unique blade force measurements on an open site straight-bladed vertical axis wind turbine have been performed. This paper presents a method for measuring the tangential and normal forces on a 12-kW vertical axis wind turbine prototype with a three-bladed... see more
