Saab fait voler une pièce de fuselage d’avion de combat imprimée en 3D

Le constructeur suédois Saab est parvenu, pour la première fois, à faire voler un avion équipé d'une pièce extérieure imprimée en 3D. L'avionneur utilise la technologie de la fabrication additive depuis quatre ans, notamment pour imprimer des pièces internes, précise L'Usine Nouvelle. La pièce, une trappe située sur le flanc arrière du fuselage de l'appareil, un modèle Gripen, a été imprimée sur la base du scan de la pièce originelle. Parfaitement ajustée à l'avion, elle n'a montré « aucun changement structurel visible après le vol d'essai », assure Hakan Stake, responsable du projet, dans un communiqué. Cette démonstration devrait, à terme, « permettre au personnel sur le terrain d'avoir accès à des pièces de rechange ajustées individuellement, d'éviter les réparations d'urgence ou de cannibaliser un appareil déjà endommagé », souligne-t-il. Il estime par ailleurs que cette solution permettra de réduire le nombre de pièces transportées lors du déploiement d'un appareil et de réduire son temps de réparation. De nombreuses étapes de certification du matériau utilisé, un polyamide 2200, couramment utilisé dans la fabrication additive, sont encore nécessaires avant de déployer la technologie sur le terrain.

    U.S. Army Opens 5-Year Search For Stinger Missile Replacement

    Steve Trimble The U.S. Army has started a long-term search for a replacement for the Raytheon FIM-92 Stinger short-range air defense surface-to-air missile system, with a contract award for up to 8,000 missiles planned by fiscal 2026. Any replacement for the Stinger must be compatible with the Initial Mobile-Short-Range Air Defense (IM-SHORAD), which uses the Stinger Vehicle Universal Launcher, according to a market survey released on Nov. 10 by the Army Contracting Command at Redstone Arsenal, Alabama. “The Army is conducting a SHORAD study which will inform efforts to modernize and to address emerging threats, which may increase the demand for MANPADS capable missiles,” said the sources sought notice. The new missile must also be able to defeat fixed-wing ground attack aircraft, rotary wing aircraft and unmanned aircraft systems (UAS) in a size class that ranges between the Boeing Insitu Scan Eagle and the Textron AAI RQ-7, which are examples of Group 2 and Group 3 UAS. The Army is extending the service life of the Stinger Block 1, but the original version of the Stinger with a reprogrammable microprocessor will become obsolete in fiscal 2023, the notice said. The sources sought notice asked interested companies to supply a wide range of information, such as a rough order of magnitude estimate for the cost and schedule of developing and delivering up 8,000 missiles. The Stinger defined the role of a man-portable air defense system quickly after the Army launched development in 1972. Though designed for ground-launch by a human, the missile has also been integrated on fixed-wing aircraft, helicopters and large UAS. The all-up round includes the 1.52 m-long FIM-92 Stinger missile, a launch tube and a fire control and aiming system. The missile itself is guided by an infrared/ultraviolet seeker, and controlled with four small rectangular fins. https://aviationweek.com/special-topics/air-dominance/us-army-opens-5-year-search-stinger-missile-replacement
