    In order to strengthen the energy density of wind flowing through the wind turbine, a system which can highly collect wind energy is presented and the author analysed the optimal conversion rate of wind energy under various working conditions. It also gives the: theoretical and practical maximal value of the nominal utility coefficient of wind ener-gy Theoretical analysis and experiments show that the optimal conver-sion rate of wind energy of the system depends on the stagnant state of nature wind, exit pressure of the system and the adiabatie exponent of air. The nominal utility coefficient of wind energy of the system can exceed that of conventional wind energy conversion system (WECS) by several times or even over ten times. The condusion is that the system will be able to increase the output power of wind turbine of the same size by several times to over ten times.

    In this paper, one new type wind energy conversion system called "Inclined Axis Wind Turbine" is introduced and brief analyses of its characteristics and behaviour are presented. It has a great future, and espetially suits to the specific areas which are not suitable for installing the Horizontal Axis Wind Turbine, such as the water, the beach and the desert. The Momentum-Blade theory is deduced which is widely used to calculate performances of Horizontal Axis Windjurbine. A concept of Thrust Linear-density is led into so that the Momentum-Blade theory can be used in the case that the induced velocity in-homogeneous ly distributes along the actutor, for example, the Inclined Axis Wind Turbine. With the help of analytic Geometry of Three Dimensions, relations among all variables are deduced, an aerodynamic model of the IAWT thus can be established by use of the deduced Momentum-Blade theory. This model can computer performances of the IAWT, design and optimize blades and provide the theoretical foundation to plan the whole turbine. Otherwise, the model can count performances of HAWT in crabbing to limit rotating speed. At last, several relationship curves are presented.
