TL;DR: It is found that: a) predictions of the time domain aeroelastic response and of the flutter speed are accurate for all modifications of the structure; and b) the computational efficiency of the proposed aeroElastic reduced order model is linearly proportional to the number of structural configurations considered.

TL;DR: In this paper, a reduced-order model is proposed to predict gust loads using computational fluid dynamics is prohibitively expensive and unrealistic for parametric searches, and the model is parametric with respect to the gust disturbance.

TL;DR: In this paper, the effects of control input time delay on closed-loop transonic computational aeroelastic analysis were investigated, and a controller for a time-delay system may be designed using the same aeroservo-elastic reduced order model, incurring in no extra costs or complications.

TL;DR: Gust load alleviation using computational fluid dynamics as source of the aerodynamic predictions is carried out in the time domain using an aeroservoelastic reduced-order model.

TL;DR: A reduced-order model based on block Arnoldi algorithm to quickly predict flutter boundary of aeroelastic system is investigated in this paper, where a mass-damper-spring dynamic system is tested, which shows that the low dimension system produced by the Arnoldi method can keep a good dynamic property with the original system in low and high frequencies.
