Structural instability caused by self exciting aerodynamic forces (flutter) can be used as an effective input source for small scale energy harvesters. The self exciting aerodynamic force exerted on a T-shape cantilever causes periodic vibration, which can be converted into electric power through an electromagnetic transducer. Due to the complexities inherent in the fluid-structure interaction ...

Aspects of the development process of a flight simulation environment within a Simulink Project are presented. In particular, special attention is given to the control surfaces for longitudinal motion for three different trailing-edge control surface configurations, which differ in number and spanwise size of the individual surfaces. The entire modeling and simulation process consists of four m...

Large amplitude flexural vibration characteristics of functionally graded material plates under aerodynamic load are investigated here using the finite element approach. Material properties of the plate are assumed to be graded in the thickness direction according to a simple power-law distribution and the effective material properties are evaluated based on the rule of mixture. The formulation...

Maximum vertical forces produced by flying animals can be difficult to identify unequivocally, but potentially indicate general limits to aerodynamic force and muscle power output. We used two methods (i.e. incremental addition of supplemental mass and asymptotic load lifting) to determine both the intraspecific allometry of and methodological differences in estimates of maximum flight performa...

This paper builds on previous research by the authors which determined the global state-of-the-art of constructing tall buildings by surveying the most active specialist tall building professionals around the globe. That research identified the effect of wind on tower cranes as a highly ranked, common critical issue in tall building construction. The research reported here presents a design for...

This paper focuses on the design of a cascade within a cold stream thrust reverser during the early, conceptual stage of the product development process. A reliable procedure is developed for the exchange of geometric and load data between a two dimensional aerodynamic model and a three dimensional structural model. Aerodynamic and structural simulations are carried out using realistic operatin...

Microjets arranged on the wing surfaces of civil transport aircraft have been shown to great potential in suppressing high-frequency gust loads. This paper presents a study aerodynamic load reduction supercritical airfoil using tilted microjets by solving Reynolds-averaged Navier-Stokes (RANS) equations. The numerical method was first validated against experimental and previous data. Afterward,...
