ANALYTICAL MODELS FOR ROTOR TEST MODULE, STRUT, AND BALANCE FRAME DYNAMICS IN THE 40- BY 80-FT WIND TUNNEL

摘要

A mathematical model is developed for the dynamics of a wind tunnel support system consisting of a balance frame, struts, and an aircraft or test module. Data are given for several rotor test modules in the Ames 40- by 80-Ft Wind Tunnel. A model for ground resonance calculations is also described.
