Improving the Forward Link of the Future Airport Data Link by Space-Time Coding [PDF]

open access: yes, 2010
In the context of the future communication system for the airport surface operations (AeroMACS), we investigate the 2×1 Alamouti scheme applied to the 802.16e standard for improving the performance of the forward link.

Advanced numerical simulations of turbulent separations in the vicinity of aeronautical vehicle walls

open access: yes, 2022
La communauté scientifique a consacré des efforts importants depuis plusieurs décennies visant à une meilleure compréhension de la turbulence pariétale, principalement sur des configurations d’écoulements canoniques. Toutefois, la simulation numérique de ces derniers est souvent menée à un nombre de Reynolds limité par le coût de calcul des approches ...

Unsteady aerodynamic analysis of space shuttle vehicles. Part 1: Summary report [PDF]

open access: yes
An analysis of the unsteady aerodynamics of space shuttle vehicles was performed. The results show that slender wing theory can be modified to give the potential flow static and dynamic characteristics over a large Mach number range from M = 0 to M 1. A
