  À Saclay, la DGA simule l’altitude pour tester les moteurs en conditions extrêmes

  L'Usine Nouvelle consacre un article au Centre d'Essais des Propulseurs du Ministère des Armées, situé sur le plateau de Saclay (Essonne), qui dispose de moyens uniques en Europe pour reproduire au sol les conditions de vols extrêmes subies par les aéronefs. Le centre technique utilise l'eau, venue des étangs voisins de Versailles, qui, amenée aux températures et aux pressions voulues, permet de récréer les flux d'air et les conditions atmosphériques de vol dans de grands caissons capables d'accueillir des moteurs. Les cinq caissons atmosphériques du centre permettent de reproduire des conditions de vol extrêmes, que ce soit en termes d'altitude (jusqu'à 20 000 mètres), de vitesse (jusqu'à Mach 3) et de température (de - 70 à + 250 °C). « Par rapport à un vol réel, nous maîtrisons mieux les tests et nous pouvons plus facilement étudier les paramètres qui nous intéressent », explique Marie-José Martinez, la directrice du site. Au-delà des programmes d'armement, le centre propose également des prestations aux grands motoristes mondiaux, tels que Safran ou Rolls-Royce. L'avion de combat SCAF pourrait aussi en bénéficier.

  Lockheed Martin Invites Innovators and Entrepreneurs to Join the Next Space Age with 'Open Space' Satellite Innovation Project

  Company Releases Satellite Specs; Offers New Opportunities to Aspiring Space Technologists SUNNYVALE, Calif., Feb. 8, 2018 /PRNewswire/ -- For the first time, Lockheed Martin (NYSE:LMT) has publicly released specifications for its satellite platforms with the goal of offering new opportunities for collaboration to companies aspiring to send innovative technologies to space. As part of a new satellite innovation initiative called Lockheed Martin Open Space, and building on expertise from the more than 800 satellites Lockheed Martin has produced, the company is publishing technical details about the payload accommodation information for its flagship LM 2100 satellite platform, its LM 400 small satellite, and two variants of its new LM 50 nanosat series. In an event yesterday in Silicon Valley, Lockheed Martin invited start-ups, researchers and established companies alike to propose technologies that could help solve some of today's most pressing challenges in space. With numerous launches and hosted payload slots on the docket, the company is looking to collaborate with a new generation of companies to find opportunities to put innovations in orbit and beyond. "Our goal with Lockheed Martin Open Space is twofold: first, to help more companies and innovators do amazing things in space, and second, to create new avenues for collaboration so we can move faster to tackle our customers' most pressing challenges," said Rick Ambrose, executive vice president of Lockheed Martin Space. "We're not just offering launch slots, we're ready to help new companies integrate their groundbreaking technologies with powerful satellite platforms. We believe there's significant untapped potential out there waiting to be unleashed." The company is looking for non-proprietary technologies that will help protect, connect and inspire the world. Potential applications include helping first responders address crises faster, studying the environment, creating ultra-high-capacity communications links and adapting low-cost commercial technology to the punishing environments of space. Interested companies or individuals can download the payload accommodation specifications at www.lockheedmartin.com/openspace and submit their concepts online. The submission page will be open from now through May 11. A team of Lockheed Martin experts will review each submission and follow up to discuss opportunities and provide feedback to submitters. "We're ready to explore and collaborate on new opportunities, and we're challenging the best and brightest to join us," said Ambrose. "Space isn't just a place to go. It's a place to do. So let's get new innovators plugged in to tomorrow's space opportunities. Let's collaborate on the country's toughest challenges. Let's do great things in space together." The venerable LM 2100 is the foundation for more than 40 satellites in orbit today, including weather, missile warning and commercial communications satellites. The LM 400 is a reconfigurable bus that can go to LEO and GEO orbits and can be delivered as quickly as 24 months from order. The LM 50 is a small but powerful satellite series that can host a wide array of remote sensing, communications and scientific payloads.
