Oliver Garrow, co-founder and Chief Technology Officer for Elytron, reports that Elytron is evaluating the feasibility of using existing airframes to build initial prototypes for the 10-seat aircraft as a means of accelerating development, and extending its design concept to include unmanned platforms (drones).<\/p>\n<div id=\"attachment_9745\" style=\"width: 538px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2015\/03\/garrow-10S.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-9745\" class=\"size-large wp-image-9745\" alt=\"10S, the largest model so far in conceptual design, would cruise at 414 mph\" src=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2015\/03\/garrow-10S-528x257.jpg\" width=\"528\" height=\"257\" srcset=\"http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2015\/03\/garrow-10S-528x257.jpg 528w, http:\/\/cafe.foundation\/blog\/wp-content\/uploads\/2015\/03\/garrow-10S-300x146.jpg 300w\" sizes=\"auto, (max-width: 528px) 100vw, 528px\" \/><\/a><p id=\"caption-attachment-9745\" class=\"wp-caption-text\">10S, the largest model so far in conceptual design, would carry 10 at 414 mph<\/p><\/div>\n<p>Elytron was founded in 2013 with Gregory Bruell, programmer and executive, as CEO and Co-Founder along with Oliver\u00a0to provide a faster, safer, and a longer-range alternative to helicopters for the oil and gas, emergency medical services, and air taxi markets. Oliver worked on the design concept over a 10-year R&amp;D period during which he conducted experiments were conducted with 1\/4<sup>th<\/sup> scale convertiplanes models on Moffett Field.\u00a0 Testing included full-size airframe modeling, extended flight, and computational fluid dynamics (CFD) simulations. The popular Verticopter flying-wing design with in-wing propulsion was the most successful of these prototypes but still had aerodynamic limitations. In 2012, Oliver created the new and optimized wing configuration to address all of the earlier design limitations.<\/p>\n<p>As explained by Oliver, \u201cThe Elytron aircraft architecture combines three sets of wings: one pair of rotary wings called \u2018proprotors,\u2019 mounted along a single tilt-wing in a central position, and two joined pairs of fixed wings. The plane has superior glide ratios and low stall speeds because of its low wing-loading design, and also displays excellent Short Take-off and Landing (STOL) capabilities.\u201d<\/p>\n<p>Elytron aircraft are claimed to be capable of achieving airspeeds two to three times those of equivalently powered helicopters. The airframe has also been optimized for low drag at the higher airspeeds due to its unique distribution across 3 sets of wings. Stall performance is claimed to be very safe as it borrows from airframes using a front wing with canard-type stall response. Fixed wing planes are also far more fuel efficient than rotary wing aircraft, reducing operational costs and increasing range. The combination of the speed of a fixed wing plane and the vertical take-off of a helicopter will allow for applications such as air taxi from city-center to city-center.<\/p>\n<p>The Elytron mechanism for controlling the plane during vertical flight has far fewer parts than helicopter swash plates. Elytron\u2019s design has no complex hub but instead distributes the parts across the tilt-wing, making them lighter and easier to inspect and maintain, according to Oliver. All of the tilt-wing actuators have redundant control. In the case of engine failure, the airframe&#8217;s superior glide ratio will eliminate the need for autorotation, which is a requirement in any helicopter.<\/p>\n<p>The anticipated benefits of the unique configuration and its promised performance are essential to the success of the new company. \u00a0Best wishes to Oliver and Greg in this endeavor.<\/p>\n<div id=\"facebook_like\"><iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=http%3A%2F%2Fcafe.foundation%2Fblog%2Felytron-shows-poc-demonstrator-heli-expo-2015%2F&amp;layout=standard&amp;show_faces=true&amp;width=500&amp;action=like&amp;font=segoe+ui&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:500px; height:80px;\" allowTransparency=\"true\"><\/iframe><\/div>","protected":false},"excerpt":{"rendered":"<p>\u00a0Since last August at AirVenture 2014, Elytron Aircraft, LLC has made great progress.\u00a0 The aircraft on display at Oshkosh last year was promising, but about half finished.\u00a0 The completed two-seat, proof-of-concept (POC) airframe shown March 3rd through 5th this year at the HAI Heli Expo in Orlando, Florida seems ready to go and remarkably light [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[16,14],"tags":[6016,6015,6019,6018,1468,830,6017,831,6020],"class_list":["post-9742","post","type-post","status-publish","format-standard","category-diesel_powerplants","category-sustainable_ga","tag-elytron-aircraft","tag-gregory-bruell","tag-hai-heli-expo","tag-joined-wing-design","tag-moffett-field","tag-oliver-garrow","tag-pivoting-center-wing","tag-verticopter","tag-vtol-aircraft"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 -
