Design of the aluminum alloy twist gear wheel with three tooth used in roots rotors blower based on parameterization;

Design of twisted blade for micro axial fans and its investigation of aerodynamic performance;

By the principle of Radial Equilibrium ,an equation was derived to describe the radial distribution of throughflow velocity,by which a design approach was newly proposed for twisted blades of micro axial fans.

A nonuniform distribution is presented for the axial velocity along the spanwise direction on the impeller outlet,by which an approach is proposed to design the twisted blade for micro axial fans considering the nonuniform axial velocity.

The development and application of solid turbine technique and twisted blade technique are analyzedin this paper,And then the prospect of solid turbine with ring and twisted blades is also discusse

The twisted blade as an important component of the centrifugal pump,the manufacture process and the precision are importamt factors in quality of centrifugal pump.

Authors of this paper used UG technology to establish distorted blade 3 dimension models.

The double-suction centrifugal pumps with distorted blade have complicated blade shape and multi- flow channels characteristics.

Taking the fourth and the sixth stage blades of a certain aero-engine compressor for example,the blade static frequencies and the kinetic frequencies in some given revolutions are first calculated in consideration of the effects of both temperature corresponding to compressor blade working state and blade twist.
