Acoustic Metamaterials in Aeronautics [PDF]
Applied Sciences (Switzerland), 2018 Metamaterials, man-made composites that are scaled smaller than the wavelength, have demonstrated a huge potential for application in acoustics, allowing the production of sub-wavelength acoustic absorbers, acoustic invisibility, perfect acoustic mirrors

Statistical methods for critical scenarios in aeronautics [PDF]
ESAIM: Proceedings and Surveys, 2015 We present numerical results obtained on the CEMRACS project Predictive SMS proposed by Safety Line. The goal of this work was to elaborate a purely statistical method in order to reconstruct the deceleration profile of a plane during

Additive Manufacturing of Aluminum Alloys for Aeronautic Applications: Advantages and Problems
Metals, 2023 In aeronautics, additive manufacturing (AM) leads to specific benefits, mainly connected to topological optimization for weight reduction, the decrease in “buy-to-fly” ratio, and the operations of maintenance, repair, and overhaul. Al alloys processed by

Design and Optimization of a Large Turboprop Aircraft
Aerospace, 2021 This paper proposes a feasibility study concerning a large turboprop aircraft to be used as a lower environmental impact solution to current regional jets operated on short/medium hauls. An overview of this market scenario highlights that this segment is

Nature, 1922 PLEASE allow me to protest against Mr. A. R. Low's attack in NATURE of January 5, p. 12, on the “slug,” which was not introduced by Prof. Bairstow, but probably by Prof. Fleeming Jenkin about thirty years ago. The slug does not lead to any evasion of Newton's laws any more than the poundal which was introduced by Prof. James Thomson. All such terms are

Comparative Analysis of the Aeronautical Certification Process Against Nonionizing Radiation and the Management Proposal for Ionizing Radiation [PDF]
Journal of Aerospace Technology and Management, 2022 Today, the certification process for onboard electro-electronic systems against nonionizing radiation can be considered mature and independent, having its own set of requirements.
