  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.

  Here’s what we know about Turkey’s newly launched homemade frigate

  By: Burak Ege Bekdil ANKARA, Turkey — Turkey on Jan. 23 launched its first locally built frigate, the I-class TCG Istanbul, advancing a program that involves the production of four corvettes and four frigates. Under the MILGEM program, Turkey manufactured and delivered four Ada-class corvettes to the Navy. The Istanbul is the first of the four I-class frigates. The Istanbul was built under a 2019 contract awarded by the government procurement agency SSB to STM, a government-controlled defense company. The warship will be used in advanced air defense, naval warfare and patrolling missions, and it will support underwater warfare missions. It will be delivered to the Navy in 2023. “The MILGEM program dates back to early 2000s. But it is delivering critical platforms just when needed, i.e., when Turkey needs hard power to support its assertive foreign policy in the eastern Mediterranean,” defense analyst Ozgur Eksi said. Turkey and its traditional Aegean rival Greece came close to military conflict several times during 2020 due to their disputes over continental shelf, airspace, territorial waters, demilitarization of Greek islands and islets, air traffic centers, and exclusive economic zones in addition to the broader territorial disputes around Cyprus. The I-class frigates will feature weapons systems including a locally made 16-cell MDAS vertical launching system (a total of 64 surface-to-air missiles yet to be specified); four-by-four SSM launch canisters for the Atmaca weapon; an Aselsan-made 76mm Gokdeniz close-in weapon system; two Aselsan-made 25mm machine guns; and a HIZIR torpedo countermeasures system. The ship class' specifications are: Dimensions: Length: 113.2 meters; Beam: 14.4 meters; Draught: 4.05 meters Displacement: 3,000 tons Speed: Max: 29-plus knots; Economic: 14 knots Range with economic speed: About 5,700 nautical miles Main Propulsion: CODAG, two MTU 20V 4000 M93L diesel engines (driving two shafts) and a LM2500 gas turbine (in CODAG configuration) Power generation: Four diesel generators Platforms: Capacity to carry two S70 Seahawk helicopters (one in the hangar and one on the platform); Two rigid hull inflatable boats Endurance: Minimum 15 days of operational capability without replenishments https://www.defensenews.com/naval/2021/01/25/heres-what-we-know-about-turkeys-newly-launched-homemade-frigate
