The Influence of Demoiselle Aircraft on Light and General Aviation Design
(Rosemead, CA, 2013-04)
In 1907, aviation pioneer Santos-Dumont had the idea of building a very light airplane. He designed and built the SD19, the
Demoiselle, an aircraft with a 6 meter wing span and a 24 HP engine of his own design. The ...
Reduction of torsional vibrations excited by electromechanical interactions in more electric systems
(IEEE-Inst Electrical Electronics Engineers, 2021)
This paper studies the excitation of torsional vibrations by electromechanical interaction after the connection of electrical loads. Electrical generation and power system in aircraft are becoming of key importance, ...

An approach to aircraft seat comfort using interface pressure mapping
(IOS PRESSAMSTERDAM, 2012)
The objective of the present study is to propose a method to dynamically evaluate discomfort of a passenger seat by measuring the interface pressure between the occupant and the seat during the performance of the most ...
Direct ethanol fuel cell as aircraft APU: a study for onboard waste heat recovery
(2018-02-01)
An advanced concept of jet aircraft (known as “more electric aircraft”) available nowadays requires electrically driven systems. In this scenario, application of low-temperature fuel cells in aircraft is an interesting ...
Sensitivity analysis of stack power uncertainty in a PEMFC-based powertrain for aircraft application
(Pergamon-Elsevier Science Ltd, 2015-08)
Experimental data concerning the reliability of fuel cell systems (FCS) in aviation are still unavailable to technical community, while assessing reliability of a component or a whole system represents a fundamental aspect ...

(2006-07-01)
Weight reduction and improved damage tolerance characteristics were the prime drivers to develop new family of materials for the aerospace/ aeronautical industry. Aiming this objective, a new lightweight Fiber/ Metal ...
Aircraft selection with DEA's triple index: an approach for sustainability
(2014)
The objective of this paper is to present a benefit-cost ranking of 127 civil transport aircraft; this ranking was determined considering a new data envelopment analysis (DEA) approach, called triple index, which combines ...
On Nonlinear Dynamics and an Optimal Control Design to a Longitudinal Flight
(Asme-amer Soc Mechanical Eng, 2008-01-01)
In this work, we analyzed a bifurcational behavior of a longitudinal flight nonlinear dynamics, taking as an example the F-8 aircraft Crusader. We deal with an analysis of high angles of attack in order to stabilize the ...
