Research on the Relationships between Blade Angles and External Characteristics of a Centimeter Scale Pneumatic Turbine
A pneumatic motor based on the principle of reaction micro turbine has been developed with a rotor diameter of 24 mm. The turbine motor includes a planet-gear reducer with gear ratio of 6.5, generates a maximum mechanical power of 248W with total efficiency 60%. It has been tested to speeds up to 10,000rpm on shaft end. Based on the developed cm-scale micro reaction turbine motors prototype, the mathematical models about the blade angles and its external characteristic parameters were built and carried out, and then their relationships are researched and obtained when the blade angles change within possible ranges.
