Wind turbines reliability is affected by stochastic factors in the turbulent inflow and wind turbine structures. On one hand, the variability in wind dynamics and the inherent stochastic structures result in random loads on wind turbine rotor and tower. On the other hand, the inherent structural uncertainties caused by imperfect control of manufacturing process introduce unpredictable failures ...

Scope of the analysis presented in this work was the improvement in the design of a microturbine for dental applications. The initial choice was an impulse turbine operating in subsonic regime with air as working fluid and a behavior similar to Turgo turbines. The work was performed in several stages: the first step focused on documentation of these turbines, followed by a dimensional study bas...

The use of wind power for energy production, renewable energy is one of the oldest methods for tapping. Socio-economic development and use of renewable energy is an essential component of economic development. Tidal energy, wind energy, etc., such as abundant renewable energy sources and reduce dependence on fossil fuels can help. With increased concern for environment now days led to the resea...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

The U.S. Army Ordnance Center and School and Pacific Northwest Laboratory have developed a system that employs Artificial Neural Network (ANN) technology to perform diagnosis and prognosis of fuel flow problems in the AGT-1500 gas turbine engine of the M1A1 Abrams tank. This paper describes the design and prototype development of the diagnostic system, referred to as "TEDANN" for Turbine Engine...

The problem of robust H∞ dynamic output feedback control design with pole placement constraints is studied for a linear parameter-varying model of a floating wind turbine. A nonlinear model is obtained and linearized using the FAST software developed for wind turbines. The main contributions of this paper are threefold. Firstly, a family of linear models are represented based on an affine param...
