DYNAMIC CONTROLLING OF PUMP BLADE SHAPE BASED ON HERMITE CURVE FORMULA

Abstract

Abstract: Hermite curve is adopted for constructing the stream - line on pump blade. A new method to control the blade shape dynamically on computer screen is proposed. The blade shape designed by this method is met the needs of blade angle and include angle for any stream-line effectively. This is very useful for CAD system. It make the blade drawing process known as Equal - angle Conversion method that used in manual style widely possible in CAD software. An example for the application of this method has been given.

Key words: CAD, Dynamic controlling, Hermite curve, Pump Blade shape
