LEVERAGING TECHNICAL INGENUITY THEY
Prosperity and the level of economic development of a country (as expressed through the annual gross domestic product per capita-GDP/place), I increase the sustainable and accelerated by mobilizing and leveraging international best technical ingenuity they the country’s population (expressed through specific annual number of patents, i.e. the number of international patents for invention obtained relative to the number of inhabitants of the country). The work of updating the data aspects of the situation in this area, with respect to Romania.
Keywords: GDP-place, innovation, necessary measures
Cuvinte cheie: PIB-loc, inovaţie, măsuri necesare
NOTES ON THE MECHANICAL STRESSES OF THE
BLADES OF HORIZONTAL AXIS WIND TURBINES
The paper presents an analysis of mechanical stresses on the blades of a small horizontal axis wind turbine.
Keywords: wind turbines, forces, deformations
Cuvinte cheie: turbine eoliene, forţe, deformări
NOTES ON A STRATEGY OF USING THE WATER FROM
A HYDROPOWER STATION LAKE
The paper discusses a method to predict the use of water in case of a
hydropower station.
Keywords: hydroelectric, water resources, rationality, compensation

NOTES ON THE BEHAVIOUR OF HORIZONTAL
AXIS WIND TURBINES
The paper presents an analysis of the behaviour of horizontal axis wind turbines in particular working regimes.
Keywords: wind turbines, functional analysis
Cuvinte cheie: turbine eoliene, analiză funcţională
NOTES ON THE INFLUENCE OF SPEED FIELD ON
THE GEOMETRY OF HORIZONTAL AXIS WIND TURBINES
Unlike hydraulic turbines, wind turbines operate ”in open apparatus”.
Thus, the field of velocities and pressures has direct influence on the operation
of the turbine. The paper presents an analysis of the influence of the speed
field on the geometry of the blades of horizontal axis wind turbines.
Keywords: wind turbines, geometry, optimization
Cuvinte cheie: turbine eoliene, geometrie, optimizare
