So Moog Inc. engineered this testbed to more accurately simulate the forces. It has a probe mounted to a cart that rides on a track and an actively controlled suspension system that supports the drogue. Beneath the refueling probe assembly on the cart is a dynamometer that measures forces and moments on the probe's mast during impact. Past beds were based on a simple drop test.</div> <div class="field-image-promo"> <img class="imagefield imagefield-field_image_promo" width="595" height="335" alt="" src="http://machinedesign.com/site-files/machinedesign.com/files/AerialRefueling.jpg?1406555690" /> </div> <div class="field-link-target"> <span>Open In New Window:&nbsp;</span> No </div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/aerial-refueling-just-got-better-navys-new-testbed" target="_blank">read more</a></p> Defense Mon, 28 Jul 2014 13:51:00 +0000 39751 at http://machinedesign.com The Missile Technology Behind the Malaysian Jet Tragedy http://machinedesign.com/defense/missile-technology-behind-malaysian-jet-tragedy <div class="field-deck"> While accusations fly about who's responsible, technologists speculate about the technology used to down a Malaysian passenger jet over the Ukraine. </div> <div class="node-body article-body">There are several surface-to-air Soviet missle technologies capable of reaching the Malaysian passenger jet shot down over the Ukraine.</div> <div class="field-content-focus"> <span>Content Classification:&nbsp;</span> Curated </div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/defense/missile-technology-behind-malaysian-jet-tragedy" target="_blank">read more</a></p> http://machinedesign.com/defense/missile-technology-behind-malaysian-jet-tragedy#comments Defense Fri, 18 Jul 2014 12:36:00 +0000 39331 at http://machinedesign.com The First Eight X Airplanes: From Mach 1 to Almost 7 http://machinedesign.com/technologies/first-eight-x-airplanes-mach-1-almost-7 <div class="node-body gallery-body">Here’s a look at the first 13 years of X airplanes, going from 1946 through 1959.</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/technologies/first-eight-x-airplanes-mach-1-almost-7" target="_blank">read more</a></p> http://machinedesign.com/technologies/first-eight-x-airplanes-mach-1-almost-7#comments Technologies Defense Thu, 05 Jun 2014 21:03:00 +0000 38141 at http://machinedesign.com Video Playlist: AUVSI Unmanned Systems 2014 http://machinedesign.com/defense/video-playlist-auvsi-unmanned-systems-2014 <div class="field-byline"> Curtis Ellzey </div> <div class="node-body gallery-body">Check out all of the videos taken at AUVSI Unmanned Systems 2014, brought to you by Machine Design and Engineering TV.</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/defense/video-playlist-auvsi-unmanned-systems-2014" target="_blank">read more</a></p> http://machinedesign.com/defense/video-playlist-auvsi-unmanned-systems-2014#comments Defense News Wed, 28 May 2014 17:41:00 +0000 37851 at http://machinedesign.com Gallery: Drones and UAVs at the AUVSI show http://machinedesign.com/defense/gallery-drones-and-uavs-auvsi-show <div class="node-body gallery-body">The recently concluded Association for Unmanned Vehicle Systems International show provided many examples of cutting-edge drone technology</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/defense/gallery-drones-and-uavs-auvsi-show" target="_blank">read more</a></p> http://machinedesign.com/defense/gallery-drones-and-uavs-auvsi-show#comments Defense Tue, 20 May 2014 20:52:00 +0000 37541 at http://machinedesign.com An Off-Roading Helicopter Takes Off http://machinedesign.com/automotive/roading-helicopter-takes <div class="node-body article-body">The Black Knight Transformer, an off-road vehicle that can take-off and fly like a helicopter, successfully completed initial flight tests, according to its developer.</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/automotive/roading-helicopter-takes" target="_blank">read more</a></p> http://machinedesign.com/automotive/roading-helicopter-takes#comments Automotive Technologies Defense Thu, 17 Apr 2014 14:10:00 +0000 36571 at http://machinedesign.com How thrusters and controls on NASA’s LADEE work (print title "Making Ladee Last") http://machinedesign.com/defense/how-thrusters-and-controls-nasa-s-ladee-work-print-title-making-ladee-last <div class="node-body article-body">Using a set of three instruments on the LADEE, scientists are measuring the chemical composition of the moon’s atmosphere.
