概要

論文の詳細を見る
The sailwing has various special characteristics due to its flexible structure. In order to estimate a variety of airfoil shape modes and steady state stability of the single membrane sailwing as a representative of the lift characteristics of a sailwing, a systematical method of analysis is present in three different trailing edge conditions. Through calculation examples, various modes of airfoil shapes and the steady state stability of each mode of the sailwing for each trailing edge condition are shown. The relationship between these characteristics and parameters of sailwing taking account of elasticities such as initial tension is also demonstrated. These characteristics are related to an abrupt change in airfoil shape and C_L-α curves of the single membrane sailwings.
