Analysis of Aerodynamic and Vibration Characteristics of a Micro Quad-rotor Helicopter with Low Reynolds Number
摘要
Abstract
Aerodynamic and vibration characteristics of a micro quad-rotor helicopter were studied based on finite element method. A three dimensional physical model of the flow field was established. By adding boundary conditions, the flow field was analyzed numerically using the finite volume method and its aerodynamic characteristics were obtained. Then the aerodynamic force was loaded to the helicopter structure to get the stress distribution and find out where the maximum stress occurs. Finally, the first six vibration modes and their vibration characteristics were obtained after the modal analysis of the micro quad-rotor helicopter.关键词
