Estudo e otimização de uma asa sob efeito de hélice na configuração tractor para redução de arrasto
(Universidade Federal de Minas GeraisUFMG, 2017-05-04)
This thesis presents a study of propeller effects on drag of a tractor wing and a wing form optimization proposal of a representative regional turboprop wing. In this study, the propeller is modeled as a disk with infinitesimal ...
New data on the humerotriceps of penguins and its implications in the evolution of the fossa tricipitalis
(Taylor and Francis Ltd., 2017-11)
A paddle-shaped wing, the general morphology of the humerus, and the muscles involved in wing movement are among the most characteristic adaptations to diving in penguins. Particularly, the humeral fossa tricipitalis and ...

Análise numérica das características aerodinâmicas de uma asa de baixo alongamento com propulsão distribuída
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2020-06-15)
Distributed propulsion concept expands the boundaries of aircraft designs, therefore, the study of aerodynamic effects due to propulsion/wing interaction is extremely important for the elaboration of a wing as efficient ...

Osteosclerosis in the extinct cayaoa bruneti (aves, Anseriformes): Insights on behavior and flightlessness
(Asociacion Paleontologica Argentina, 2015-06)
Many studies on avian microanatomy have established a relationship between high bone compactness (i.e., higher degree of osteosclerosis) and diving behavior. Greatest degrees of compactness have been observed in the femora ...
Development of a conceptual design methodology focused on solar aircrafts
(Universidade Federal de Minas GeraisUFMG, 2014-07-30)
This work presents the studies to associated solar aircraft project. Characteristics of existing solar aircraft, their history and developments and associated technical challenges, as well as their limitations and potential ...
Análise das características aerodinâmicas da asa DEPWIM numa configuração ótima com propulsão elétrica distribuída
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2022-05-31)
The present work aims to theoretically study, through a numerical technique, involving
computational fluid dynamics, the influence of electrical propulsion distributed in the flow field
around the sections of the semi-span ...
General-Purpose Object-Oriented Framework for Vorticity-Dominated Flow Simulation
(American Institute of Aeronautics and Astronautics, 2020-06)
This paper describes the development of a computational framework for aerodynamic simulations based on the unsteady vortex lattice method under the object-oriented programming paradigm. The effort aims to fulfill the ...
