Global Study of the Performance of a Propeller with a Variable Pitch and a Variable Diameter

Article Preview

Abstract:

The paperwork presents a study to determine the performance parameters of a propeller characterized by the variable diameter in combination with the variable pitch, a technical method of improving the efficiency of the propeller for different power modes. This solution allows varying the load of the propeller by varying the propeller blade diameter in connection with the changing pitch blade at a constant speed mode setting. The solution allows varying the propeller area to control the air flow and to obtain the optimum load at different stage blade angles varying the pitch into the optimum position at a constant speed mode to realize the increase of the air flow through the propeller blades at different power modes. The study is performed only in aerodynamic mode and not in the technical constructive mode.
