![]() At the slow end, Icarus V can fly at 16 mi/h with sinking speeds around 1 m/s (180 ft/min)." It is estimated that the "five" can be flown at 45 mi/h when nosed down and it will still have a better glide ratio than a standard Rogallo flying at its best L/D. "Unlike most ultralights - especially those with single-surface sections - Icarus V can be flown fast without excessive loss of glide ratio, a 'must' for cross-country flying and for penetrating one's way out of tight spots in strong winds near the crests of hills. The resulting drag provides effective glide-path control." This has been addressed by simultaneously deflecting both tip rudders, thus using them as dive brakes. Thanks to the 20° sweep and the 7° geometric twist for washout, the "five" cannot be stalled accidentally, and pitch stability is astounding! With a glide ratio around 10:1, landing in a small area could present something of a problem. Deflecting a rudder causes the craft to yaw, and the combined sweep and dihedral produces strong roll response. "Control is by the same system used in earlier Icari: pitch control is by body weight shift on parallel bars (pilot on swing seat), lateral control is through the individually controlled tip rudders. It disassembles at the centre-line in about 10-15 minutes for transportation in a car-top box. Construction time was about 200 man-hours. It was designed with an ultimate load limit in excess of 6g for a 200-lb. The efficient, computer-analysed, high-lift airfoil (TK 7315) has a foam-sheet leading edge formed over aluminum ribs. Construction is of aluminum tubing, cable (3/32") braced, and covered with fabric. Icarus V is a swept, constant-chord, flying-wing monoplane with a 32-foot span and 5-foot chord. We thought that the readers of 'Ground Skimmer' might be interested in recent developments. ![]() ![]() "Since its debut at the third Montgomery Meet, many inquiries have been received regarding the newest member of the Icarus family. Writing in 'Ground Skimmer' 8/73 (thanks to USHGA) the formality and politeness of RCGroups is a nice change of pace! (for example this post would most likely be quoted there with the sarcastic reply: "cool story bro".Icarus 5 Icarus 5 by Taras Kiceniuk From Taras Kiceniuk, Sr. I admire his creativity and designerism (is that a word? it is now!) but some of his stuff is out there, even for me And as for watching where I walk.as my user name suggest I'm also a NASIOC member.we're anything BUT careful there! haha. Sorry for rambling on and going OT (I am from the midwest ) what were we talking about? oh yeah, Frank G - we had some of his furniture on campus.pretty, but not comfortable. I wasn't even thinking about integrating the feet with the drainage holes until I started modeling it.then it became a painfully obvious direction to take the design. I had no drawing of this, just a paper model: I'm just saying I think better sketching in 3d - for example this freshman year soap dish design - I had a ton of required sketches for ideas but the final design I settled on came from building models of the drawings, seeing why they were ugly/didn't work or were overly complicated, and then fixing the model. I just like artistic functional things, but can't be troubled with stuff like physics or demanding clients, lol. Now I don't do anything creative for a career but try to fill my personal time with it. Of course I noticed I did a lot of "engineering" in highschool, decided to try architecture my first time in college, then took 5 years off to be an artisan bread baker, then went back for product/industrial design.
