WebDynamic similarity: Mass: M: ... The wind tunnel model was realized using a large length scale factor, 1/40, in order to have a quite high Reynolds number and to guarantee the possibility of a detailed reproduction of all the geometrical features. An aeroelastic model must be properly scaled in terms of natural frequencies, stiffness, inertia ... WebL i f t = q S C L. The dynamic pressure q = 1 2 ρ v 2. S is the planform area. C L is the lift coefficient. ρ is the air density. v is the air velocity. What you really want to test for is the lift coefficient - you can use that to calculate the lift force during flight for a given dynamic pressure and planform area.
WebAug 10, 2024 · In addition, the wind tunnel tests are set up with static steady conditions, with ignoring the dynamic response of the model during emergency ascent. Therefore, it is difficult to predict the roll oscillations of a model on the surface, as well as some excessive roll that occurred in the full-scale trials. ... Similar to the adding weight ...
