    La Slovaquie va acheter quatorze F-16V

    En optant pour le chasseur de Lockheed Martin, la Slovaquie ajoute un 28ème nom à la liste déjà très longue des pays utilisateurs du F-16 La Slovaquie a donc décidé de remplacer ses MiG29, hérités de l'ancienne Tchécoslovaquie, par la dernière itération du F-16, la version block 70, alias F-16V. La vente, approuvée par le département d'état américain, se monterait à un peu moins de deux milliards dollars, avions, équipements de maintenance, réacteur et radars de rechange, entrainement des équipages, missiles air-air, nacelles de désignation laser Sniper et sourire de la crémière américaine. Le F-16V a été choisi de préférence au Saab Gripen « parce qu'il coûtait moins cher et qu'il était disponible plus rapidement » ont indiqué les autorités slovaques. Celles ci ont également reconnu que le choix en faveur du F-16 était inspiré par leur volonté d'approfondir les liens avec l'Otan. Pas un mot en revanche sur la nécessité pour un pays de 5,4 millions d'habitants, enclavé entre l'Ukraine, la Hongrie, l'Autriche, la république tchèque et la Pologne, de se payer une poignée d'avions de combat neufs et hautement sophistiqués. https://www.aerobuzz.fr/breves-defense/la-slovaquie-va-acheter-quatorze-f-16v/

    Army, Uber will partner on silent rotor technology for UAVs

    By: Charlsy Panzino The Army is partnering with Uber to create safer, more lethal unmanned aerial vehicle missions. The new effort between the Army Research Laboratory and the rideshare company, announced on Tuesday, aims to create silent rotor technology. The goal is to reduce the noise caused by traditional UAV rotors. “When UAVs are doing an [intelligence, surveillance and reconnaissance] mission, they're out there collecting or observing to collect intelligence or to do surveillance,” Jaret Riddick, director of ARL's Vehicle Technology Directorate, told Army Times after the announcement. That mission is hampered, however, when the adversary can hear the UAV coming, Riddick said. “They know a certain noise in the distance means a certain type of operation is underway,” he said. “When you can do that with the advantage of not being detected ... it changes how you execute a mission.” Uber Elevate, under which the air taxi side of the company falls, is interested in noise-reduction technology because its vehicles would be operating in dense urban areas. Since Uber is a technology company, ARL will build the UAVs for testing the technology. One kind of technology Uber is looking at to solve the noise problem is the idea of having stacked rotors on a vehicle that spin in the same direction. Traditionally, UAVs have stacked rotors that spin in opposite directions. “When those rotors are spinning in opposite directions, they create a type of turbulence that contributes to noise in the operation,” Riddick said. “By having them spin in the same direction and adjusting their position to one another, research has shown that using this technique can offer advantages in performance while reducing the noise compared with traditional operations.” One of these performance advantages is more lift capability, he said. Last year, Uber announced the Dallas-Forth Worth area as its first location for flight demonstrations in 2020, and Riddick said Uber will collaborate with ARL-South researchers in Austin. Uber and ARL-South will build the infrastructure needed for testing, Riddick said, adding that progress will be checked every six months. “Uber is proud to be partnering with ARL on critical research on flying vehicle innovations that will help create the world's first urban aviation rideshare network,” Eric Allison, head of Uber Elevate, said in a news release. “Our first jointly-funded project will help us develop first of its kind rotor technology that will allow for quieter and more efficient travel. We see this initial project as the first of many and look forward to continued collaboration with the lab on innovations that will make uberAIR a reality.” https://www.armytimes.com/news/your-army/2018/05/08/army-uber-will-partner-on-silent-rotor-technology-for-uavs/

    Boeing makes hard sell for Super Hornet as Canada’s future fighter - Skies Mag

    Boeing is pulling out all the stops to convince Canada that the F/A-18E/F Super Hornet is the right future fighter, over the F-35A and Gripen E.
