Title： Ruffle and valve design of flap wing surface
Date: 2019/11/12 (Thu) 3:30 pm - 5:20 pm
Location: Engineering 5 Building B1 International Conference Hall
Summary:
In order to reduce the weight of the flapping wings, membrane-type wings are usually used, but their aerodynamic effects are limited. This presentation introduces two designs that do not increase weight, but effectively increase the aerodynamic force of the film flap: (1) The dragonfly has wrinkle flaps. This wrinkle design provides important light weight but stiffness for flapping wings. (Stiffness) has enough shape; (2) One-way valve type (check valve) flap design optimizes the boundary layer airflow control of the flap, or imitates the feather-like opening and closing freely.
