Figure 5.

Gust response of the hinged system for three different wing mass fractions, versus the fixed-wing case, with an NLC in the 30% gust. Line thickness denotes the mass of the hinged wing, from 0.2 M to 0.5 M. Plot lines become dotted at the instant the wing angle crosses 20 degrees (approximate onset of nonlinearity). (a) Normalized centre of pressure l_F/l. Notice that, with increased mass, the wing is slower to exceed the linear threshold; the model therefore captures the initial dynamics even better. (b) Resulting fuselage velocity $\dot{z}$. (c) Rejection terms for the hinged system. The higher the relative wing mass, the greater the inertial rejection at first.
