A flutter control system of an aircraft wing comprising an actuator mounted on the aircraft wing to control a control surface, flight control command unit for outputting an actuation command signal for actuating the actuator, wing-displacement measurement unit for measuring an actual displacement of a...

12. In some cases, the effects of structural nonlinearities on aircraft flutter analysis can not be neglected. 结构非线性在飞机颤振分析中有时是不可忽视的重要因素。 13. flutter的意思 13. Composite aircraft structure; flutter model; design element; finite element ...
Rigorous comparisons to the Goland wing, wings with and without stores, and a flying wing illustrate the practical applications of the theory during aircraft design. Further, the theory predicts the time to flutter of each wing for a range of representative viscoelastic materials and flow conditions...
To cause to flutter: "fluttering her bristly black lashes as swiftly as butterflies' wings" (Margaret Mitchell). n. 1. The act of fluttering. 2. A condition of nervous excitement or agitation: Everyone was in a flutter over the news that the director was resigning. 3. A commotion; a ...
19.The main difficulty on the study of aeroelasticity lies in the effects of unsteady separation, shock and viscosity to the stallflutter. 振荡叶栅的非定常分 离、粘性效应和跨音激波对失速颤振的影响成为当前气动弹性力学的 主要难点。 20.He is resisting,flutteringhis tiny wings, and still making ...

Likened to domestic pigeons fluttering their wings in response to an agitation (a dovecote being a structure built to house and raise them). The unexpected entrance of an exuberant young woman caused a bit of a flutter in the dovecote at the old Men's Only club. Eloise, are you mad?
The objectives of the paper are to review and investigate flutter prediction methods for realistic wings used in aircraft preliminary design. Specifically, demonstrate the flutter predictions with a recently developed method using Eigenvector Orientations (EVO). Comparisons of flutter predictions between th...
