Dynamic Scaling of a Wing Structure Model Using Topology Optimization
Autor: Éder Oliveira, Abdolrasoul Sohouli, Frederico Afonso, Roberto Gil Annes da Silva, Afzal Suleman
Publikováno v: Machines, Vol 10, Iss 5, p 374 (2022)
In this paper, a dynamic scaling methodology is introduced to devise reduced scaled models of aircraft with the objectives of minimizing the development cost and exploring the design space. A promising way to accomplish this is using Topology Optimiz

Comparison of In-Flight Measured and Computed Aeroelastic Damping: Modal Identification Procedures and Modeling Approaches
Autor: Roberto da Cunha Follador, Carlos Eduardo de Souza, Adolfo Gomes Marto, Roberto Gil Annes da Silva, Luis Carlos Sandoval Góes
Publikováno v: Journal of Aerospace Technology and Management, Vol 8, Iss 2, Pp 163-177 (2016)
The Operational Modal Analysis technique is a methodology very often applied for the identification of dynamic systems when the input signal is unknown. The applied methodology is based on a technique to estimate the Frequency Response Functions and

Estimation of lift characteristics of a subscale fighter using low-cost experimental methods
Autor: Leonardo Murilo Nepomuceno, Roberto Gil Annes da Silva, Alejandro Sobron, Petter Krus, David Lundström
Publikováno v: Aircraft Engineering and Aerospace Technology. 94:1379-1389
Purpose While computational methods are prevalent in aircraft conceptual design, recent advances in mechatronics and manufacturing are lowering the cost of practical experiments. Focussing on a relatively simple property, the lift curve, this study a

On Comparison Between 0–1 Test for Chaos and Attractor Reconstruction of an Aeroelastic System
Autor: Roberto Gil Annes da Silva, José Manoel Balthazar, Michelle F. Westin
Publikováno v: Journal of Vibration Engineering & Technologies. 9:303-312
This paper aims to investigate the post-flutter nonlinearities due to the wing high aspect ratio. Flutter is an aerodynamic auto-excited phenomenon which occurs due to the coupling of two or more different vibration modes. This coupling results from
