Old Koreelah Posted April 18, 2019 Posted April 18, 2019 Any ideas on this one guys? [ATTACH]39137[/ATTACH] Dunno what it's called, but I'd like one.
Red Posted April 16, 2020 Posted April 16, 2020 Nobody in here for a while so I'll just give that last thing an ID via Google: Sigma 5 Nice looking thing, but I remain hugely sceptical about so called flying cars. Have a go at this:

Flightrite Posted February 7, 2022 Posted February 7, 2022 (edited) CH47D Chinook👍 Edited February 7, 2022 by Flightrite
onetrack Posted February 7, 2022 Posted February 7, 2022 Red, Flightrite is correct, it's a CH-47D. The CH-46 is a lighter version, powered by GE T58 turboshaft engines, the CH47 is a heavier lift version powered by the Lycoming T55 turboshaft engine.
red750 Posted February 7, 2022 Posted February 7, 2022 You're right, acted too quickly. I am amazed I hav not profiled te Chinook. Now have the photos, will do so tonight. The black obscuring the bouyancy hull fooled me. Have to get my glasse checked. 1

Old Koreelah Posted February 11, 2022 Posted February 11, 2022 I found that image yonks ago in an article about the Graf Zeppelin, which was to be the Nazi’s first Aircraft carrier. The Stuka was modified to allow it to operate off this short field and I’m assuming the unusual features are massive stall fences, with windows for visibility. Love to know more about it. 1
facthunter Posted February 11, 2022 Posted February 11, 2022 Gone to a lot of trouble with Fairings there. Nev 1
onetrack Posted February 11, 2022 Posted February 11, 2022 Nev, it was a design doomed to failure largely due to the manufacturer being forced to use the highly unreliable Continental inverted V12 XIV-1430 engines, which ran at a higher-than-normal operating temperature to try and increase the power output. The Continental inverted V12 was prone to fires as a result, and an engine fire destroyed the only flying prototype of the XP-67 Moonbat. In addition, the amount of effort put into streamlining and fairings did not produce the level of performance promised - and only equalled the other, "regular design" military aircraft of the era. The aircraft designers also entered into areas of aerodynamic instability with the streamlining, which was likely not fully understood until decades later, and only counteracted by electronic stability controls of our modern electronic era. The Moonbat also suffered badly from Dutch Roll, and it had undesirable handling qualities as it approached stall speed, which led test pilots to decline spin testing, as they suspected the aircraft would develop an unrecoverable spin, if spin testing was tried. So - despite looking like something that would be a world-beater in design, the Moonbat was really only an interesting design exercise that failed to deliver what it promised - even though the looks promised something out of 50 years into the future. https://en.wikipedia.org/wiki/McDonnell_XP-67
facthunter Posted February 12, 2022 Posted February 12, 2022 Short coupling and mass distribution affects Dutch roll or later with sweepback at higher altitudes. Yaw dampers fix all that. Some of these futuristic designs ended up with crook load carrying ability. Few planes can carry a payload exceeding their Empty weight. Some of our U/L's do quite well in this respect. Nev 1
Flightrite Posted March 20, 2022 Posted March 20, 2022 (edited) I was over in sheep shaggers country recently and spotted the old Convair, still operational for Chatham’s but the gas man said they are retiring them, going jet! Edited March 20, 2022 by Flightrite
cscotthendry Posted March 22, 2022 Posted March 22, 2022 (edited) Saw this today… Something special about this plane! Edited March 22, 2022 by cscotthendry

spacesailor Posted March 23, 2022 Posted March 23, 2022 It,s a Glider !. With weird covering material. spacesailor 1
onetrack Posted March 23, 2022 Posted March 23, 2022 It's a shame no RB-1 Conestoga's appear to have survived. Being made entirely out of spot-welded stainless steel, corrosion would have been non-existent, and I'd imagine the structural lifespan would have been huge. 1 1
cscotthendry Posted March 23, 2022 Posted March 23, 2022 Yes indeed it is a Conestoga, made by Budd. And yes it was made of spot welded stainless steel. Only 17 ever flew. Here's a closer look at the very interesting spot welding. 1
Flightrite Posted March 23, 2022 Posted March 23, 2022 There sure has been some ugly A/C over the years!😂
