SYSTEM AND THE METHOD FOR AERODYNAMIC FORCES ANALYSIS OF HELICOPTER ROTOR

摘要

PURPOSE: A helicopter rotor aerodynamic analysis system and aerodynamic analysis process method are provided to accurately and rapidly analyze the aerodynamic of a rotor by abnormally analyzing the aerodynamic of a rotor based on a panel method. CONSTITUTION: An aerodynamic characteristic analysis unit(23) analyzes a rotor aerodynamic analysis code which a potential based panel method is applied to. A hovering/forwarding flying estimator(25) estimates the aerodynamic characteristic of a rotor blade. A tip vortex analyzer(27) analyzes the tip vortex of the rotor blade. A pre-processor(10) is connected to the effort analysis module and receives the shape of the rotor blade and a boundary condition.
